test: Update client id/secret -> client_info

Remove file-based caching of OAuth client credentials and implement automatic
client lifecycle management for test fixtures.

Changes:
- Add RFC 7592 client deletion function in auth/client_registration.py
- Remove cache_file parameter from _create_oauth_client_with_scopes helper
- Update all OAuth credential fixtures to use yield/finalizer pattern
- Add automatic client cleanup at end of test session (best-effort)
- Remove persistent .nextcloud_oauth_*.json cache files

Benefits:
- No persistent cache files cluttering repository
- Fresh OAuth clients created for each test session via DCR
- Automatic cleanup attempts (RFC 7592 DELETE endpoint)
- Cleaner test environment with proper fixture lifecycle

Note: Client deletion may fail due to Nextcloud authentication middleware
(logged as warning). The key improvement is removing persistent cache files.
OAuth clients may accumulate in Nextcloud but can be cleaned manually.

+### MCP Response Patterns
+
+**CRITICAL: Never return raw `List[Dict]` from MCP tools - always wrap in Pydantic response models**
+
+FastMCP serialization issue: raw lists get mangled into dicts with numeric string keys.
+
+**Pattern:**
+1. Client methods return `List[Dict]` (raw data)
+2. MCP tools convert to Pydantic models and wrap in response object
+3. Response models inherit from `BaseResponse`, include `results` field + metadata
+
+**Reference implementations:**
+- `SearchNotesResponse` in `nextcloud_mcp_server/models/notes.py:80`
+- `SearchFilesResponse` in `nextcloud_mcp_server/models/webdav.py:113`
+- Tool examples: `nextcloud_mcp_server/server/{notes,webdav}.py`
+
+**Testing:** Extract `data["results"]` from MCP responses, not `data` directly.
+
 ### Testing Structure

-- **Fixtures** in `tests/conftest.py` - Shared test setup and utilities
-- Tests are marked with `@pytest.mark.integration` for selective running

+

+  - For basic auth tests: rebuild with `docker-compose up --build -d mcp`
+  - For OAuth tests: rebuild with `docker-compose up --build -d mcp-oauth`
 
 #### Testing Best Practices
 - **MANDATORY: Always run tests after implementing features or fixing bugs**
   - Run tests to completion before considering any task complete
   - If tests require modifications to pass, ask for permission before proceeding
-  - Use `docker-compose up --build -d mcp` to rebuild MCP container after code changes
+  - **Rebuild the correct container** after code changes:
+    - For basic auth tests (most common): `docker-compose up --build -d mcp`
+    - For OAuth tests: `docker-compose up --build -d mcp-oauth`
 - **Use existing fixtures** from `tests/conftest.py` to avoid duplicate setup work:
-  - `nc_mcp_client` - MCP client session for tool/resource testing
+  - `nc_mcp_client` - MCP client session for tool/resource testing (uses `mcp` container)
+  - `nc_mcp_oauth_client` - MCP client session for OAuth testing (uses `mcp-oauth` container)
   - `nc_client` - Direct NextcloudClient for setup/cleanup operations
   - `temporary_note` - Creates and cleans up test notes automatically
   - `temporary_addressbook` - Creates and cleans up test address books
   - `temporary_contact` - Creates and cleans up test contacts
 - **Test specific functionality** after changes:
-  - For Notes changes: `uv run pytest tests/integration/test_mcp.py -k "notes" -v`
-  - For specific API changes: `uv run pytest tests/integration/test_notes_api.py -v`
+  - For Notes changes: `uv run pytest tests/server/test_mcp.py -k "notes" -v`
+  - For specific API changes: `uv run pytest tests/client/notes/test_notes_api.py -v`
+  - For OAuth changes: `uv run pytest tests/server/test_oauth*.py -v` (remember to rebuild `mcp-oauth` container)
 - **Avoid creating standalone test scripts** - use pytest with proper fixtures instead
 
+#### Writing Mocked Unit Tests
+
+For client-layer tests that verify response parsing logic, use mocked HTTP responses instead of real network calls:
+
+**Pattern:**
+```python
+import httpx
+import pytest
+from nextcloud_mcp_server.client.notes import NotesClient
+from tests.conftest import create_mock_note_response
+
+async def test_notes_api_get_note(mocker):
+    """Test that get_note correctly parses the API response."""
+    # Create mock response using helper functions
+    mock_response = create_mock_note_response(
+        note_id=123,
+        title="Test Note",
+        content="Test content",
+        category="Test",
+        etag="abc123",
+    )
+
+    # Mock the _make_request method
+    mock_client = mocker.AsyncMock(spec=httpx.AsyncClient)
+    mock_make_request = mocker.patch.object(
+        NotesClient, "_make_request", return_value=mock_response
+    )
+
+    # Create client and test
+    client = NotesClient(mock_client, "testuser")
+    note = await client.get_note(note_id=123)
+
+    # Verify the response was parsed correctly
+    assert note["id"] == 123
+    assert note["title"] == "Test Note"
+    # Verify the correct API endpoint was called
+    mock_make_request.assert_called_once_with("GET", "/apps/notes/api/v1/notes/123")
+```
+
+**Mock Response Helpers in `tests/conftest.py`:**
+- `create_mock_response()` - Generic HTTP response builder
+- `create_mock_note_response()` - Pre-configured note response
+- `create_mock_error_response()` - Error responses (404, 412, etc.)
+
+**Benefits:**
+- ⚡ Fast execution (~0.1s vs minutes for integration tests)
+- 🔒 No Docker dependency
+- 🎯 Tests focus on response parsing logic
+- ♻️ Repeatable and deterministic
+
+**When to use:**
+- Testing client methods that parse JSON responses
+- Testing error handling (404, 412, etc.)
+- Testing request parameter building
+
+**When NOT to use (keep as integration tests):**
+- Complex protocol interactions (CalDAV, CardDAV, WebDAV)
+- Multi-component workflows (Notes + WebDAV attachments)
+- OAuth flows
+- End-to-end MCP tool testing
+
+**Reference Implementation:**
+- See `tests/client/notes/test_notes_api.py` for complete examples
+- Mark unit tests with `pytestmark = pytest.mark.unit`
+- Run with: `uv run pytest tests/unit/ tests/client/notes/test_notes_api.py -v`
+
 #### OAuth/OIDC Testing
-OAuth integration tests support both **automated** (Playwright) and **interactive** authentication flows:
+OAuth integration tests use **automated Playwright browser automation** to complete the OAuth flow programmatically.
 
-**Automated Testing (Default - Recommended for CI/CD):**
-- **Default fixtures**: `nc_oauth_client`, `nc_mcp_oauth_client` now use Playwright automation by default
-- Uses Playwright headless browser automation to complete OAuth flow programmatically
-- All Playwright fixtures: `playwright_oauth_token`, `nc_oauth_client`, `nc_mcp_oauth_client`, `nc_oauth_client_playwright`, `nc_mcp_oauth_client_playwright`
-- Requires: `NEXTCLOUD_HOST`, `NEXTCLOUD_USERNAME`, `NEXTCLOUD_PASSWORD` environment variables
+**OAuth Testing Setup:**
+- **Main fixtures**: `nc_oauth_client`, `nc_mcp_oauth_client` - Use Playwright automation
+- **Shared OAuth Client**: All test users authenticate using a single OAuth client
+  - **Created fresh for each test session** via Dynamic Client Registration (DCR)
+  - Matches production MCP server behavior (one client, multiple user tokens)
+  - Each user gets their own unique access token
+  - **Automatic cleanup**: Client is registered at session start, deleted at session end (RFC 7592)
+  - Implementation: `shared_oauth_client_credentials` fixture in `tests/conftest.py`
+  - **Note**: Client deletion may fail due to Nextcloud middleware (logged as warning). This doesn't affect tests.
+- **Available fixtures**: `playwright_oauth_token`, `nc_oauth_client`, `nc_mcp_oauth_client`
+- **Multi-user fixtures**: `alice_oauth_token`, `bob_oauth_token`, `charlie_oauth_token`, `diana_oauth_token`
+- **Requirements**: `NEXTCLOUD_HOST`, `NEXTCLOUD_USERNAME`, `NEXTCLOUD_PASSWORD` environment variables

-  ```
+# Run specific OAuth test file with visible browser for debugging
+uv run pytest tests/server/oauth/test_oauth_core.py --browser firefox --headed -v
 
-**Interactive Testing (Manual browser login):**
-- Opens system browser and waits for manual login/authorization
-- Fixtures: `interactive_oauth_token`, `nc_oauth_client_interactive`, `nc_mcp_oauth_client_interactive`
-- Requires: User to complete browser-based login when prompted
-- Useful for: Debugging OAuth flows, testing with 2FA, local development
-- **Automatically skipped in GitHub Actions CI** - Interactive fixtures check for `GITHUB_ACTIONS` environment variable

-**Test Environment Setup:**
+**Test Environment:**
+- **Two MCP server containers are available:**
+  - `mcp` (port 8000): Uses basic auth with admin credentials - for most testing
+  - `mcp-oauth` (port 8001): Uses OAuth authentication - for OAuth-specific testing
 - Start OAuth MCP server: `docker-compose up --build -d mcp-oauth`
-- OAuth server runs on port 8001 (regular MCP on 8000)
-- Both flows register OAuth clients dynamically using Nextcloud's OIDC provider
+- **Important**: When working on OAuth functionality, always rebuild `mcp-oauth` container, not `mcp`
 
-**CI/CD Considerations:**
-- Interactive OAuth tests are automatically skipped when `GITHUB_ACTIONS` environment variable is set
-- Automated Playwright tests will run in CI/CD environments
+**CI/CD Notes:**
+- Playwright tests run in CI/CD environments
 - Use Firefox browser in CI: `--browser firefox` (Chromium may have issues with localhost redirects)

 The Nextcloud MCP (Model Context Protocol) server allows Large Language Models like Claude, GPT, and Gemini to interact with your Nextcloud data through a secure API. Create notes, manage calendars, organize contacts, work with files, and more - all through natural language.
 
-## Features
+> [!NOTE]
+> **Nextcloud has two ways to enable AI access:** Nextcloud provides [Context Agent](https://github.com/nextcloud/context_agent), an AI agent backend that powers the [Assistant](https://github.com/nextcloud/assistant) app and allows AI to interact with Nextcloud apps like Calendar, Talk, and Contacts. Context Agent runs as an ExApp inside Nextcloud and also _[exposes an MCP server](https://docs.nextcloud.com/server/stable/admin_manual/ai/app_context_agent.html#using-nextcloud-mcp-server)_ for external MCP clients.
+>
+> This project (Nextcloud MCP Server) is a **dedicated standalone MCP server** designed specifically for external MCP clients like Claude Code and IDEs, with deep CRUD operations and OAuth support. It does not require any additional AI-features to be enabled in Nextcloud beyond the apps that you intend to interact with.

 ### Tools
-Tools enable AI assistants to perform actions:
+
+The server provides 90+ tools across 8 Nextcloud apps. When using OAuth, tools are dynamically filtered based on your granted scopes.
+
+#### Available Tool Categories
+
+| App | Tools | Read Scope | Write Scope | Operations |
+|-----|-------|-----------|-------------|------------|
+| **Notes** | 7 | `mcp:notes:read` | `mcp:notes:write` | Create, read, update, delete, search notes |
+| **Calendar** | 20+ | `mcp:calendar:read` | `mcp:calendar:write` | Events, todos (tasks), calendars, recurring events, attendees |
+| **Contacts** | 8 | `mcp:contacts:read` | `mcp:contacts:write` | Create, read, update, delete contacts and address books |
+| **Files (WebDAV)** | 12 | `mcp:files:read` | `mcp:files:write` | List, read, upload, delete, move files and folders |
+| **Deck** | 15 | `mcp:deck:read` | `mcp:deck:write` | Boards, stacks, cards, labels, assignments |
+| **Cookbook** | 13 | `mcp:cookbook:read` | `mcp:cookbook:write` | Recipes, import from URLs, search, categories |
+| **Tables** | 5 | `mcp:tables:read` | `mcp:tables:write` | Row operations on Nextcloud Tables |
+| **Sharing** | 10+ | `mcp:sharing:read` | `mcp:sharing:write` | Create, manage, delete shares |
+
+**Example Tools:**
 - `nc_notes_create_note` - Create a new note
+- `nc_cookbook_import_recipe` - Import recipes from URLs with schema.org metadata
 - `deck_create_card` - Create a Deck card
 - `nc_calendar_create_event` - Create a calendar event
+- `nc_calendar_create_todo` - Create a CalDAV task/todo
 - `nc_contacts_create_contact` - Create a contact
-- And many more...
+- `nc_webdav_upload_file` - Upload a file to Nextcloud
+- And 80+ more...
+
+> [!TIP]
+> **OAuth Scope Filtering**: When connecting via OAuth, MCP clients will only see tools for which you've granted access. For example, granting only `mcp:notes:read` and `mcp:notes:write` will show 7 Notes tools instead of all 90+ tools. See [OAuth Troubleshooting - Limited Scopes](docs/oauth-troubleshooting.md#limited-scopes---only-seeing-notes-tools) if you're only seeing a subset of tools.
+>
+> **Known Issue**: Claude Code and some other MCP clients may only request/grant Notes scopes during initial connection. Track progress at [#234](https://github.com/cbcoutinho/nextcloud-mcp-server/issues/234).

+# MCP Server Comparison: Nextcloud MCP Server vs Context Agent
+
+This document compares the two MCP server implementations in the Nextcloud ecosystem:
+
+1. **Nextcloud MCP Server** (this project) - Standalone MCP server for external access to Nextcloud
+2. **Context Agent MCP Server** - MCP server embedded within Nextcloud as an External App
+
+## Executive Summary
+
+Both projects expose Nextcloud functionality via the Model Context Protocol (MCP), but serve different purposes and audiences:
+
+- **Nextcloud MCP Server**: Brings Nextcloud OUT to external MCP clients (Claude Code, etc.)
+- **Context Agent**: Brings external MCP servers IN to Nextcloud's AI Assistant
+

+## Tool Definition Patterns
+
+### Nextcloud MCP Server
+
+```python
+# Static registration at startup
+def configure_notes_tools(mcp: FastMCP):
+    @mcp.tool()
+    async def nc_notes_create_note(
+        title: str,
+        content: str,
+        category: str,
+        ctx: Context
+    ) -> CreateNoteResponse:
+        """Create a new note"""
+        client = get_client(ctx)  # Auto-detects auth mode
+        note_data = await client.notes.create_note(
+            title=title,
+            content=content,
+            category=category
+        )
+        return CreateNoteResponse(
+            id=note_data["id"],
+            title=note_data["title"],
+            etag=note_data["etag"]
+        )
+
+    # Resources for structured data access
+    @mcp.resource("nc://Notes/{note_id}")
+    async def nc_get_note_resource(note_id: int):
+        """Get user note using note id"""
+        ctx = mcp.get_context()
+        client = get_client(ctx)
+        note_data = await client.notes.get_note(note_id)
+        return Note(**note_data)
+```
+
+**Key Features**:
+- Native FastMCP `@mcp.tool()` decorator
+- Pydantic models for type safety
+- MCP Resources support
+- Comprehensive error handling with McpError
+- Context-based client resolution

+async def get_tools(nc: Nextcloud):
+    @tool
+    @safe_tool
+    def list_calendars():
+        """List all existing calendars by name"""
+        principal = nc.cal.principal()
+        calendars = principal.calendars()
+        return ", ".join([cal.name for cal in calendars])
+
+    @tool
+    @dangerous_tool
+    def schedule_event(
+        calendar_name: str,
+        title: str,
+        description: str,
+        start_date: str,
+        end_date: str,
+        attendees: list[str] | None,
+        start_time: str | None,
+        end_time: str | None
+    ):
+        """Create a new event or meeting in a calendar"""
+        # Parse dates and times
+        start_datetime = datetime.strptime(start_date, "%Y-%m-%d")
+        # ... event creation logic
+        principal = nc.cal.principal()
+        calendar = {cal.name: cal for cal in calendars}[calendar_name]
+        calendar.add_event(str(c))
+        return True
+
+    return [list_calendars, schedule_event, ...]
+
+def get_category_name():
+    return "Calendar and Tasks"
+
+def is_available(nc: Nextcloud):
+    return True  # or check capabilities
+```
+
+**Key Features**:
+- LangChain `@tool` decorator

+
+### Nextcloud MCP Server Safety
+
+**No built-in safety classification**:
+- All tools treated equally
+- Relies on MCP client for validation
+- OAuth scopes could control permissions
+- User must review all actions
+
+## Error Handling
+
+### Nextcloud MCP Server
+
+```python
+try:
+    note_data = await client.notes.create_note(...)
+    return CreateNoteResponse(...)
+except HTTPStatusError as e:
+    if e.response.status_code == 403:
+        raise McpError(ErrorData(
+            code=-1,
+            message="Access denied: insufficient permissions"
+        ))
+    elif e.response.status_code == 413:
+        raise McpError(ErrorData(
+            code=-1,
+            message="Note content too large"
+        ))
+    elif e.response.status_code == 409:
+        raise McpError(ErrorData(
+            code=-1,
+            message="Note with this title already exists"
+        ))
+```
+
+**Features**:
+- Comprehensive HTTP status code handling
+- User-friendly error messages
+- Specific error codes
+- Guidance on resolution
+
+### Context Agent
+
+```python
+def schedule_event(...):
+    """Create event"""
+    # ... implementation
+    calendar.add_event(str(c))
+    return True  # Simple boolean return
+```
+
+**Features**:
+- Minimal error handling
+- Exceptions propagate to agent
+- LangChain handles retries
+- Agent interprets failures

+## Summary
+
+Both MCP servers serve important but different roles in the Nextcloud ecosystem:
+
+### Nextcloud MCP Server (This Project)
+- **Purpose**: Expose Nextcloud to external MCP clients
+- **Strength**: Deep CRUD operations, OAuth security, standalone deployment
+- **Audience**: External developers, Claude Code users, integration builders
+
+### Context Agent MCP Server
+- **Purpose**: Bring AI agent capabilities to Nextcloud users

+
+- **Import recipes from websites** using schema.org metadata
+- Full CRUD operations for recipes
+- Search and organize with categories and keywords
+- Support for structured recipe data (ingredients, instructions, nutrition, etc.)
+- Configure app settings and trigger reindexing
+
+### Schema.org Recipe Format
+
+The Cookbook app uses the [schema.org/Recipe](https://schema.org/Recipe) specification for structured recipe data. This standard format includes:
+
+- **Basic info**: Name, description, image, URL
+- **Timing**: Preparation time, cooking time, total time (ISO8601 format like `PT30M`)
+- **Ingredients**: List of ingredients with quantities
+- **Instructions**: Step-by-step cooking instructions
+- **Metadata**: Category, keywords/tags, yield (servings)
+- **Nutrition**: Optional nutrition information
+
+### Usage Examples
+
+#### Import Recipe from URL
+
+Many recipe websites include schema.org metadata. The import tool automatically extracts this data:
+
+```python
+# Import from a recipe website
+await nc_cookbook_import_recipe(
+    url="https://www.example.com/recipes/chocolate-cake"
+)
+# Returns: Recipe object with all extracted data
+```
+
+#### Create Recipe Manually
+
+```python
+# Create a new recipe from scratch
+await nc_cookbook_create_recipe(
+    name="Homemade Pizza",
+    description="Classic homemade pizza with fresh ingredients",
+    ingredients=[
+        "500g pizza dough",
+        "200g tomato sauce",
+        "300g mozzarella cheese",
+        "Fresh basil leaves",
+        "Olive oil"
+    ],
+    instructions=[
+        "Preheat oven to 250°C (480°F)",
+        "Roll out the pizza dough",
+        "Spread tomato sauce evenly",
+        "Add mozzarella cheese",
+        "Bake for 10-12 minutes",
+        "Top with fresh basil and olive oil"
+    ],
+    category="Main Course",
+    keywords="italian,vegetarian,quick",
+    prep_time="PT20M",      # 20 minutes
+    cook_time="PT12M",      # 12 minutes
+    total_time="PT32M",     # 32 minutes
+    recipe_yield=4          # 4 servings
+)
+```
+
+#### Update Recipe
+
+```python
+# Update recipe details (only specified fields are changed)
+await nc_cookbook_update_recipe(
+    recipe_id=123,
+    description="Updated: Classic homemade pizza - now with video tutorial!",
+    url="https://example.com/videos/pizza-tutorial",
+    keywords="italian,vegetarian,quick,video"
+)
+```
+
+#### Search and Filter
+
+```python
+# Search recipes by keyword
+results = await nc_cookbook_search_recipes(query="chocolate")
+
+# List all categories
+categories = await nc_cookbook_list_categories()
+# Returns: [{"name": "Desserts", "recipe_count": 15}, ...]
+
+# Get recipes in a category
+desserts = await nc_cookbook_get_recipes_in_category(category="Desserts")
+
+# List all keywords/tags
+keywords = await nc_cookbook_list_keywords()
+# Returns: [{"name": "chocolate", "recipe_count": 8}, ...]
+
+# Get recipes with specific tags
+quick_meals = await nc_cookbook_get_recipes_with_keywords(keywords=["quick", "30min"])
+```
+
+#### Manage Configuration
+
+```python
+# Configure the Cookbook app
+await nc_cookbook_set_config(
+    folder="Recipes",           # Folder path in user's files
+    update_interval=15,         # Auto-rescan every 15 minutes
+    print_image=True           # Print images with recipes
+)
+
+# Trigger manual reindex after file changes
+await nc_cookbook_reindex()
+```
+
+### Time Format (ISO8601 Duration)
+
+Recipe times use ISO8601 duration format:
+
+| Duration | Format | Example |
+|----------|--------|---------|
+| 15 minutes | `PT15M` | Prep time |
+| 1 hour | `PT1H` | Baking time |
+| 1 hour 30 minutes | `PT1H30M` | Total time |
+| 45 seconds | `PT45S` | Mixing time |
+| 2 hours 15 minutes | `PT2H15M` | Slow cooking |
+
+### Tips for Recipe Import
+
+**Best practices for importing recipes from URLs:**
+
+1. **Look for schema.org support**: Most modern recipe sites include schema.org metadata
+2. **Check import quality**: Review imported recipes for completeness
+3. **Handle duplicates**: The API prevents duplicate imports by recipe name
+4. **Edit after import**: Update imported recipes with personal notes or adjustments
+
+**Common recipe websites with good schema.org support:**
+- AllRecipes
+- Food Network
+- BBC Good Food
+- Serious Eats
+- Bon Appétit
+- Many food blogs using recipe plugins
+
+### Organizing Your Recipes
+
+**Categories**: Organize recipes by type (Appetizers, Main Course, Desserts, etc.)
+- Use `nc_cookbook_list_categories` to see all categories
+- Filter by category with `nc_cookbook_get_recipes_in_category`
+
+**Keywords/Tags**: Tag recipes with searchable terms (vegetarian, quick, spicy, etc.)
+- Use `nc_cookbook_list_keywords` to see all tags
+- Filter by tags with `nc_cookbook_get_recipes_with_keywords`
+- Search across all fields with `nc_cookbook_search_recipes`
+
+**Reindexing**: The Cookbook app maintains a search index
+- Automatically scans at configured intervals
+- Manually trigger with `nc_cookbook_reindex` after bulk changes
+- Required after modifying recipe files directly in WebDAV

+# JWT OAuth Reference - Nextcloud MCP Server
+
+**Last Updated:** 2025-10-23
+**Status:** Production Ready

+
+## Overview
+
+The Nextcloud MCP Server supports OAuth authentication with both **JWT** (RFC 9068) and **opaque** tokens. JWT tokens are recommended for production use as they enable:
+
+- **Faster validation** - No HTTP call needed for token verification
+- **Direct scope extraction** - Scopes embedded in token claims
+- **Dynamic tool filtering** - Users only see tools they have permission to use
+- **Signature verification** - Cryptographic validation using JWKS
+
+### Key Features
+
+- ✅ **JWT Token Support** - RFC 9068 compliant access tokens with RS256 signatures
+- ✅ **Custom Scopes** - `mcp:notes:read` and `mcp:notes:write` for read/write access control
+- ✅ **Dynamic Tool Filtering** - Tools filtered based on user's token scopes
+- ✅ **Scope Challenges** - RFC-compliant `WWW-Authenticate` headers for insufficient scopes
+- ✅ **Protected Resource Metadata** - RFC 9728 endpoint for scope discovery
+- ✅ **Backward Compatible** - BasicAuth mode bypasses all scope checks
+
+### Supported Scopes
+
+| Scope | Description | Tool Count |
+|-------|-------------|------------|
+| `mcp:notes:read` | Read-only access to Nextcloud data | 36 tools |
+| `mcp:notes:write` | Write access to create/modify/delete data | 54 tools |
+
+All MCP tools (90 total) require at least one of these scopes. Standard OIDC scopes (`openid`, `profile`, `email`) are also supported.
+
+---
+
+## JWT vs Opaque Tokens
+
+The Nextcloud OIDC app supports two token formats, configured per-client:
+
+### JWT Tokens (Recommended)
+
+**Advantages:**
+- ✅ Fast validation - JWT signature verified locally using JWKS
+- ✅ Direct scope extraction from `scope` claim in payload
+- ✅ Standard approach (RFC 9068)
+- ✅ No additional HTTP calls for validation
+
+**Disadvantages:**
+- ⚠️ Larger size (~800-1200 chars vs 72 chars for opaque)
+- ⚠️ Token payload visible to client (not an issue for access tokens)
+
+**Token Structure:**
+```json
+{
+  "header": {
+    "typ": "at+JWT",
+    "alg": "RS256",
+    "kid": "..."
+  },
+  "payload": {
+    "iss": "http://localhost:8080",
+    "sub": "admin",
+    "aud": "client_id",
+    "exp": 1234567890,
+    "iat": 1234567890,
+    "scope": "openid profile email mcp:notes:read mcp:notes:write",
+    "client_id": "...",
+    "jti": "..."
+  }
+}
+```
+
+### Opaque Tokens
+
+**Advantages:**
+- ✅ Smaller size (72 characters)
+- ✅ No payload visible to client
+- ✅ Direct scope access via introspection endpoint (RFC 7662)
+
+**Disadvantages:**
+- ❌ Higher latency - Requires HTTP call to introspection endpoint
+- ❌ Slower than JWT signature verification (network roundtrip)
+
+**Validation Method:**
+Opaque tokens are validated using the **introspection endpoint** (`/apps/oidc/introspect`), which returns:
+- Token active status
+- Scope claim (direct access, no inference needed)
+- User information (`sub`, `username`)
+- Token metadata (`exp`, `iat`, `client_id`)
+
+Falls back to userinfo endpoint only if introspection is unavailable.
+
+**When to Use:**
+- Use **JWT tokens** for production (better performance, no HTTP call)
+- Use **opaque tokens** for compatibility with clients that don't support JWT
+
+---
+
+## Scope-Based Authorization
+
+### Scope Definitions
+
+The MCP server uses **coarse-grained scopes** for simplicity:
+
+| Scope | Operations | Examples |
+|-------|------------|----------|
+| `mcp:notes:read` | Read-only access | Get notes, search files, list calendars, read contacts |
+| `mcp:notes:write` | Write operations | Create notes, update events, delete files, modify contacts |
+
+### Standard OIDC Scopes
+
+| Scope | Description | Required |
+|-------|-------------|----------|
+| `openid` | OIDC authentication | Yes |
+| `profile` | User profile information | Recommended |
+| `email` | Email address | Recommended |
+
+### Recommended Configurations
+
+**Full Access:**
+```
+openid profile email mcp:notes:read mcp:notes:write
+```
+
+**Read-Only:**
+```
+openid profile email mcp:notes:read
+```
+
+**No Custom Scopes (OIDC only):**
+```
+openid profile email
+```
+
+### Implementation
+
+All 90 MCP tools are decorated with scope requirements:
+
+```python
+@mcp.tool()
+@require_scopes("mcp:notes:read")
+async def nc_notes_get_note(note_id: int, ctx: Context):
+    """Get a note by ID (requires mcp:notes:read scope)"""
+    ...
+
+@mcp.tool()
+@require_scopes("mcp:notes:write")
+async def nc_notes_create_note(title: str, content: str, ctx: Context):
+    """Create a note (requires mcp:notes:write scope)"""
+    ...
+```
+
+**Coverage:**
+- ✅ 36 read tools decorated with `@require_scopes("mcp:notes:read")`
+- ✅ 54 write tools decorated with `@require_scopes("mcp:notes:write")`
+- ✅ 90/90 tools covered (100%)
+
+### Dynamic Tool Filtering
+
+The MCP server implements **dynamic tool filtering** - users only see tools they have permission to use. This applies to **both JWT and Bearer (opaque) tokens** in OAuth mode:
+
+**Token with `mcp:notes:read` only:**
+- `list_tools()` returns 36 read-only tools
+- Write tools are hidden from the tool list
+
+**Token with `mcp:notes:write` only:**
+- `list_tools()` returns 54 write-only tools
+- Read tools are hidden from the tool list
+
+**Token with both scopes:**
+- `list_tools()` returns all 90 tools
+
+**Token with no custom scopes:**
+- `list_tools()` returns 0 tools (all require `mcp:notes:read` or `mcp:notes:write`)
+
+**BasicAuth mode:**
+- `list_tools()` returns all 90 tools (no filtering)
+
+**Note:** JWT tokens include scopes in the token payload, while Bearer tokens retrieve scopes via the introspection endpoint. Both methods provide reliable scope information for filtering.
+
+### Scope Challenges
+
+When a tool is called without required scopes, the server returns a `403 Forbidden` response with a `WWW-Authenticate` header:
+
+```http
+HTTP/1.1 403 Forbidden
+WWW-Authenticate: Bearer error="insufficient_scope",
+                  scope="mcp:notes:write",
+                  resource_metadata="http://server/.well-known/oauth-protected-resource/mcp"
+```
+
+This enables **step-up authorization** - clients can detect missing scopes and trigger re-authentication to obtain additional permissions.
+
+### Protected Resource Metadata (PRM)
+
+The server implements RFC 9728's Protected Resource Metadata endpoint:
+
+**Endpoint:** `GET /.well-known/oauth-protected-resource/mcp`
+
+**Response:**
+```json
+{
+  "resource": "http://localhost:8001/mcp",
+  "scopes_supported": ["mcp:notes:read", "mcp:notes:write"],
+  "authorization_servers": ["http://localhost:8080"],
+  "bearer_methods_supported": ["header"],
+  "resource_signing_alg_values_supported": ["RS256"]
+}
+```
+
+This allows OAuth clients to discover supported scopes before requesting authorization.
+
+---
+
+## Configuration
+
+### Docker Services
+
+The development environment includes two MCP server variants:
+
+| Service | Port | Auth Type | Token Type | Use Case |
+|---------|------|-----------|------------|----------|
+| `mcp` | 8000 | BasicAuth | N/A | Development, testing |
+| `mcp-oauth` | 8001 | OAuth | JWT (configurable) | OAuth testing with JWT tokens |
+
+### OAuth Service Configuration
+
+The `mcp-oauth` service uses **Dynamic Client Registration (DCR)** by default and is configured to request JWT tokens:
+
+**Default Configuration (DCR with JWT tokens):**
+```yaml
+mcp-oauth:
+  build: .
+  command: ["--transport", "streamable-http", "--oauth", "--port", "8001", "--oauth-token-type", "jwt"]
+  ports:
+    - 127.0.0.1:8001:8001
+  environment:
+    - NEXTCLOUD_HOST=http://app:80
+    - NEXTCLOUD_MCP_SERVER_URL=http://localhost:8001
+    - NEXTCLOUD_PUBLIC_ISSUER_URL=http://localhost:8080
+    - NEXTCLOUD_OIDC_SCOPES=openid profile email mcp:notes:read mcp:notes:write
+  volumes:
+    - oauth-client-storage:/app/.oauth  # Persist DCR credentials
+```
+
+**With Pre-Configured Credentials:**
+```yaml
+mcp-oauth:
+  build: .
+  command: ["--transport", "streamable-http", "--oauth", "--port", "8001", "--oauth-token-type", "jwt"]
+  ports:
+    - 127.0.0.1:8001:8001
+  environment:
+    - NEXTCLOUD_HOST=http://app:80
+    - NEXTCLOUD_MCP_SERVER_URL=http://localhost:8001
+    - NEXTCLOUD_PUBLIC_ISSUER_URL=http://localhost:8080
+    - NEXTCLOUD_OIDC_CLIENT_ID=<your_client_id>      # Skips DCR
+    - NEXTCLOUD_OIDC_CLIENT_SECRET=<your_client_secret>  # Skips DCR
+```
+
+**Key Points:**
+- **No credentials needed** - DCR automatically registers the client on first start
+- **Credentials persist** - Saved to `.nextcloud_oauth_client.json` and reused
+- **JWT tokens** - Use `--oauth-token-type jwt` for better performance
+- **Token verifier supports both** - Can handle JWT and opaque tokens
+- **Pre-configured credentials** - Providing `CLIENT_ID`/`CLIENT_SECRET` skips DCR
+
+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `NEXTCLOUD_HOST` | Nextcloud base URL | `http://localhost:8080` |
+| `NEXTCLOUD_MCP_SERVER_URL` | MCP server external URL for OAuth callbacks | (required in OAuth mode) |
+| `NEXTCLOUD_PUBLIC_ISSUER_URL` | Public issuer URL for JWT validation | (uses `NEXTCLOUD_HOST`) |
+| `NEXTCLOUD_OIDC_CLIENT_ID` | Pre-configured OAuth client ID | (optional - uses DCR if unset) |
+| `NEXTCLOUD_OIDC_CLIENT_SECRET` | Pre-configured OAuth client secret | (optional - uses DCR if unset) |
+| `NEXTCLOUD_OIDC_CLIENT_STORAGE` | Path to persist DCR-registered credentials | `.nextcloud_oauth_client.json` |
+| `NEXTCLOUD_OIDC_SCOPES` | Space-separated scopes to request | `"openid profile email mcp:notes:read mcp:notes:write"` |
+| `NEXTCLOUD_OIDC_TOKEN_TYPE` | Token format: `"jwt"` or `"Bearer"` | `"Bearer"` |
+
+### Dynamic Client Registration (DCR)
+
+The MCP server supports **automatic OAuth client registration** using the OIDC Discovery registration endpoint. This eliminates the need for manual client creation in most cases.
+
+**How It Works:**
+
+When the MCP server starts in OAuth mode, it follows this **three-tier credential loading strategy**:
+
+```
+1. Environment Variables (Highest Priority)
+   ├─ NEXTCLOUD_OIDC_CLIENT_ID
+   └─ NEXTCLOUD_OIDC_CLIENT_SECRET
+
+2. Storage File (Second Priority)
+   └─ NEXTCLOUD_OIDC_CLIENT_STORAGE (.nextcloud_oauth_client.json)
+
+3. Dynamic Client Registration (Automatic Fallback)
+   ├─ Discovers registration endpoint from /.well-known/openid-configuration
+   ├─ Registers new client with requested scopes and token type
+   ├─ Saves credentials to storage file for future use
+   └─ Client credentials persist across restarts
+```
+
+**Configuration:**
+
+DCR automatically configures the client based on environment variables:
+
+```bash
+# Minimal DCR configuration (no credentials needed!)
+export NEXTCLOUD_HOST=http://localhost:8080
+export NEXTCLOUD_MCP_SERVER_URL=http://localhost:8000
+export NEXTCLOUD_OIDC_SCOPES="openid profile email mcp:notes:read mcp:notes:write"
+export NEXTCLOUD_OIDC_TOKEN_TYPE=jwt  # or "Bearer" for opaque tokens
+```
+
+**Credential Storage:**
+
+- Registered credentials are saved to `NEXTCLOUD_OIDC_CLIENT_STORAGE` (default: `.nextcloud_oauth_client.json`)
+- File has restrictive permissions (0600 - owner read/write only)
+- Credentials are reused on subsequent starts (no re-registration needed)
+- Storage file is checked for expiration (auto-regenerates if expired)
+
+**Format:**
+```json
+{
+  "client_id": "XBd2xqIisu3Kswg39Ub4BUhC36PEYjwwivx3G5nZdDgigvwKXrTHozs7m9DeoLSY",
+  "client_secret": "xNKcy0qpUSau36T60pGGdb03pMEVLXtqykxjK8YkDpoNxNcZ4ClyAT3IAEse2AKT",
+  "client_id_issued_at": 1761097039,
+  "client_secret_expires_at": 2076457039,
+  "redirect_uris": ["http://localhost:8000/oauth/callback"]
+}
+```
+
+**Benefits:**
+- ✅ Zero-configuration OAuth setup
+- ✅ Automatic credential management
+- ✅ Supports both JWT and opaque tokens
+- ✅ Credentials persist across container restarts
+- ✅ Automatic re-registration if credentials expire
+- ✅ Properly sets `allowed_scopes` for JWT token validation
+
+### Manual Client Creation
+
+Manual client creation is **optional** but may be preferred when:
+- You want explicit control over client configuration
+- You're deploying to production environments with strict security policies
+- You need to pre-provision OAuth clients before deployment
+
+**Create Client via OCC Command:**
+
+```bash
+docker compose exec app php occ oidc:create \
+  --token_type=jwt \
+  --allowed_scopes="openid profile email mcp:notes:read mcp:notes:write" \
+  "Nextcloud MCP Server" \
+  "http://localhost:8000/oauth/callback"
+```
+
+**Output:**
+```json
+{
+  "client_id": "XBd2xqIisu3Kswg39Ub4BUhC36PEYjwwivx3G5nZdDgigvwKXrTHozs7m9DeoLSY",
+  "client_secret": "xNKcy0qpUSau36T60pGGdb03pMEVLXtqykxjK8YkDpoNxNcZ4ClyAT3IAEse2AKT",
+  "token_type": "jwt",
+  "allowed_scopes": "openid profile email mcp:notes:read mcp:notes:write"
+}
+```
+
+**Configure MCP Server with Pre-Configured Credentials:**
+
+```bash
+# Option 1: Environment variables (highest priority)
+export NEXTCLOUD_OIDC_CLIENT_ID="<client_id>"
+export NEXTCLOUD_OIDC_CLIENT_SECRET="<client_secret>"
+export NEXTCLOUD_OIDC_TOKEN_TYPE="jwt"
+
+# Option 2: Storage file (second priority)
+# Save the JSON response to .nextcloud_oauth_client.json
+# Server will automatically load it on startup
+```
+
+When credentials are provided via environment variables or storage file, **DCR is skipped**.

+### Key Components
+
+**1. Token Verification** (`nextcloud_mcp_server/auth/token_verifier.py`)
+- **Three-tier validation strategy:**
+  1. **JWT verification** (lines 116-124): JWKS signature validation for JWT tokens
+  2. **Introspection** (lines 126-134): RFC 7662 endpoint for opaque tokens
+  3. **Userinfo fallback** (lines 137-142): Last resort if introspection unavailable
+- Scope extraction from token payload (JWT) or introspection response (opaque)
+- Token caching with TTL to reduce repeated validations
+- Supports both access token formats transparently
+
+**2. Scope Authorization** (`nextcloud_mcp_server/auth/scope_authorization.py`)
+- `@require_scopes()` decorator for tools
+- `get_required_scopes()` - Extract scope requirements from functions
+- `has_required_scopes()` - Check if user has necessary scopes
+- `InsufficientScopeError` exception for WWW-Authenticate challenges
+
+**3. Dynamic Filtering** (`nextcloud_mcp_server/app.py:473-516`)
+- Overrides FastMCP's `list_tools()` method
+- Filters based on user's OAuth token scopes (JWT and Bearer)
+- Only active in OAuth mode
+- Bypassed in BasicAuth mode
+
+**4. PRM Endpoint** (`nextcloud_mcp_server/app.py:503-532`)
+- `GET /.well-known/oauth-protected-resource/mcp`
+- Advertises `["mcp:notes:read", "mcp:notes:write"]`
+- RFC 9728 compliant
+
+**5. Exception Handler** (`nextcloud_mcp_server/app.py:540-563`)
+- Catches `InsufficientScopeError`
+- Returns 403 with `WWW-Authenticate` header
+- Includes missing scopes and PRM endpoint URL
+
+### Token Validation Flow
+
+The `NextcloudTokenVerifier` implements a **cascading validation strategy** that handles both JWT and opaque tokens efficiently:

+
+**Validation Priorities:**
+
+| Token Type | Method | Performance | Scope Access | Code Reference |
+|------------|--------|-------------|--------------|----------------|
+| JWT | JWKS Signature | ⚡ Fastest (local) | Direct (`scope` claim) | `token_verifier.py:156-234` |
+| Opaque | Introspection | 🔄 Medium (HTTP) | Direct (`scope` field) | `token_verifier.py:236-328` |
+| Any | Userinfo | 🐌 Slowest (HTTP + inference) | Inferred (from claims) | `token_verifier.py:330-386` |
+
+**Configuration** (`nextcloud_mcp_server/app.py:391-399`):
+```python
+token_verifier = NextcloudTokenVerifier(
+    nextcloud_host=nextcloud_host,
+    userinfo_uri=userinfo_uri,
+    jwks_uri=jwks_uri,                    # Enables JWT verification
+    issuer=jwt_validation_issuer,         # For JWT issuer validation
+    introspection_uri=introspection_uri,  # Enables introspection for opaque tokens
+    client_id=client_id,                  # Required for introspection auth
+    client_secret=client_secret,          # Required for introspection auth
+)
+```
+
+## Testing
+
+### Test Infrastructure
+
+The test suite includes comprehensive coverage for JWT OAuth and scope authorization:
+
+**Test Files:**
+- `tests/server/test_scope_authorization.py` - Scope-based authorization tests (4 tests)
+- `tests/server/test_mcp_oauth_jwt.py` - JWT OAuth integration tests
+- `tests/conftest.py` - Shared fixtures for JWT testing
+
+### Consent Scenario Tests
+
+Four test scenarios verify scope-based tool filtering with different consent levels:
+
+#### 1. No Custom Scopes (0 tools)
+```bash
+uv run pytest tests/server/test_scope_authorization.py::test_jwt_with_no_custom_scopes_returns_zero_tools -v
+```
+
+**Scenario:** JWT token with only OIDC defaults (`openid profile email`)
+**Expected:** 0 tools returned (all require `mcp:notes:read` or `mcp:notes:write`)
+**Verifies:** Security - users who decline custom scopes cannot access any MCP tools
+
+#### 2. Read-Only Access (36 tools)
+```bash
+uv run pytest tests/server/test_scope_authorization.py::test_jwt_consent_scenarios_read_only -v
+```
+
+**Scenario:** JWT token with `mcp:notes:read` only
+**Expected:** 36 read-only tools visible, write tools hidden
+**Verifies:** Read tools accessible, write tools filtered out
+
+#### 3. Write-Only Access (54 tools)
+```bash
+uv run pytest tests/server/test_scope_authorization.py::test_jwt_consent_scenarios_write_only -v
+```
+
+**Scenario:** JWT token with `mcp:notes:write` only
+**Expected:** 54 write tools visible, read tools hidden
+**Verifies:** Write tools accessible, read tools filtered out
+
+#### 4. Full Access (90 tools)
+```bash
+uv run pytest tests/server/test_scope_authorization.py::test_jwt_consent_scenarios_full_access -v
+```
+
+**Scenario:** JWT token with both `mcp:notes:read` and `mcp:notes:write`
+**Expected:** All 90 tools visible
+**Verifies:** Full access when user grants all custom scopes
+
+### Test Fixtures
+
+**OAuth Client Fixtures:**
+- `read_only_oauth_client_credentials` - Client with `mcp:notes:read` only
+- `write_only_oauth_client_credentials` - Client with `mcp:notes:write` only
+- `full_access_oauth_client_credentials` - Client with both scopes
+- `no_custom_scopes_oauth_client_credentials` - Client with OIDC defaults only
+
+**Token Fixtures:**
+- `playwright_oauth_token_read_only` - Obtains token with `mcp:notes:read`
+- `playwright_oauth_token_write_only` - Obtains token with `mcp:notes:write`
+- `playwright_oauth_token_full_access` - Obtains token with both scopes
+- `playwright_oauth_token_no_custom_scopes` - Obtains token with no custom scopes
+
+**MCP Client Fixtures:**
+- `nc_mcp_oauth_client_read_only` - MCP session with read-only token
+- `nc_mcp_oauth_client_write_only` - MCP session with write-only token
+- `nc_mcp_oauth_client_full_access` - MCP session with full access token
+- `nc_mcp_oauth_client_no_custom_scopes` - MCP session with no custom scopes
+
+### Running Tests
+
+**All consent scenario tests:**
+```bash
+uv run pytest tests/server/test_scope_authorization.py -v
+```
+
+**JWT OAuth integration tests:**
+```bash
+uv run pytest tests/server/test_mcp_oauth_jwt.py -v --browser firefox
+```
+
+**With visible browser (debugging):**
+```bash
+uv run pytest tests/server/test_mcp_oauth_jwt.py -v --browser firefox --headed
+```
+
+### Test Configuration
+
+**Playwright Browser:**
+- Default: Chromium
+- Recommended for CI: Firefox (`--browser firefox`)
+- Debugging: Add `--headed` flag
+
+**OAuth Flow:**
+- Uses automated Playwright browser automation
+- Completes OAuth consent flow programmatically
+- Creates separate OAuth client for each scenario
+- Each user gets unique access token
+

+
+## Troubleshooting
+
+### Issue: JWT Issuer Validation Failed
+
+**Symptom:**
+```
+WARNING JWT issuer validation failed: Invalid issuer
+WARNING JWT verification failed, will try other methods
+✅ Extracted scopes from access token: {'openid', 'profile'}
+```
+
+**Cause:** Token's `iss` claim doesn't match expected issuer URL. This often happens when:
+- Using `localhost` vs `127.0.0.1` inconsistently
+- MCP server uses internal URL but clients use public URL
+
+**Solution:**
+```bash
+# Option 1: Use consistent URLs
+export NEXTCLOUD_PUBLIC_ISSUER_URL=http://localhost:8080
+# Ensure all test fixtures also use localhost:8080
+
+# Option 2: Check discovery document
+curl http://localhost:8080/.well-known/openid-configuration | jq .issuer
+# Use this exact issuer in NEXTCLOUD_PUBLIC_ISSUER_URL
+```
+
+**Impact if not fixed:**
+- JWT validation falls back to userinfo endpoint
+- Scopes inferred from userinfo (only standard OIDC scopes, no custom scopes)
+- Result: 0 tools visible or incorrect tool filtering
+
+### Issue: Scopes Not Present in JWT
+
+**Symptom:** JWT token doesn't contain `scope` claim or contains empty string
+
+**Cause:** Client's `allowed_scopes` is empty or not configured
+
+**Solution:**
+```bash
+# Check client configuration
+docker compose exec app php occ oidc:list
+
+# Look for allowed_scopes in output
+# If empty, recreate client with --allowed_scopes
+docker compose exec app php occ oidc:create \
+  --token_type=jwt \
+  --allowed_scopes="openid profile email mcp:notes:read mcp:notes:write" \
+  "Client Name" \
+  "http://callback/url"
+```
+
+### Issue: All Tools Visible Despite Read-Only Token
+
+**Symptom:** User with `mcp:notes:read` token can see all 90 tools including write tools
+
+**Cause:** Server running in BasicAuth mode, not OAuth mode
+
+**Solution:**
+```bash
+# Verify OAuth mode is active
+docker compose logs mcp-oauth | grep "OAuth mode"
+
+# Should see: "Running in OAuth mode"
+
+# If not, check environment variables:
+docker compose exec mcp-oauth env | grep NEXTCLOUD_OIDC
+
+# Ensure no NEXTCLOUD_USERNAME or NEXTCLOUD_PASSWORD set
+```
+
+### Verifying DCR Scope Configuration
+
+DCR **now properly sets `allowed_scopes`** when the `scope` parameter is provided during registration.
+
+**To verify DCR scopes are working:**
+
+```bash
+# Check the registered client's allowed_scopes via database
+docker compose exec db mariadb -u nextcloud -ppassword nextcloud \
+  -e "SELECT name, allowed_scopes FROM oc_oauth2_clients WHERE name LIKE 'DCR-%' ORDER BY id DESC LIMIT 1;"
+
+# Should show your requested scopes (e.g., "openid profile email mcp:notes:read mcp:notes:write")
+```
+
+**If scopes are missing:**
+1. Ensure `NEXTCLOUD_OIDC_SCOPES` environment variable is set correctly
+2. Check MCP server startup logs for the scopes being requested
+3. Verify DCR is enabled in Nextcloud OIDC app settings
+4. Delete `.nextcloud_oauth_client.json` and restart to force re-registration
+
+### Issue: Token Type Case Sensitivity
+
+**Symptom:** JWT tokens not generated even though `token_type=JWT` set
+
+**Cause:** OIDC app checks `token_type === 'jwt'` (lowercase)
+
+**Solution:** Always use lowercase:
+```bash
+# Correct
+export NEXTCLOUD_OIDC_TOKEN_TYPE=jwt
+
+# Incorrect (will generate opaque tokens)
+export NEXTCLOUD_OIDC_TOKEN_TYPE=JWT
+```
+
+### Issue: Missing WWW-Authenticate Header
+
+**Symptom:** 403 error doesn't include `WWW-Authenticate` header
+
+**Cause:** Server not in OAuth mode, or exception not being caught
+
+**Solution:**
+```bash
+# Check server logs for OAuth mode
+docker compose logs mcp-oauth | grep "WWW-Authenticate scope challenges enabled"
+
+# Should see this during startup
+
+# Check exception handling
+docker compose logs mcp-oauth | grep "InsufficientScopeError"
+```
+
+### Debugging Tools
+
+**Check JWT contents:**
+```bash
+# Decode JWT (base64 decode the payload)
+echo "JWT_PAYLOAD_PART" | base64 -d | jq .
+```
+
+**Check database scopes:**
+```bash
+# View access tokens with scopes
+docker compose exec db mariadb -u nextcloud -ppassword nextcloud \
+  -e "SELECT id, client_id, user_id, scope FROM oc_oidc_access_tokens ORDER BY id DESC LIMIT 5;"
+
+# View user consents
+docker compose exec db mariadb -u nextcloud -ppassword nextcloud \
+  -e "SELECT user_id, client_id, scopes_granted FROM oc_oidc_user_consents;"
+```
+
+**Check server logs:**
+```bash
+# Follow JWT verification logs
+docker compose logs -f mcp-oauth | grep -E "JWT|scope|tool"
+
+# Check for issuer mismatches
+docker compose logs mcp-oauth | grep -i issuer
+```
+
+---
+
+## Production Deployment
+
+### Deployment Checklist
+
+✅ **Use JWT Tokens** - Enable `token_type=jwt` for better performance
+✅ **Configure Allowed Scopes** - Always set `allowed_scopes` on OAuth clients
+✅ **Use Pre-Configured Clients** - Avoid DCR limitation with manual client creation
+✅ **Consistent URLs** - Use same URL for `NEXTCLOUD_HOST` and `PUBLIC_ISSUER_URL`
+✅ **Secure Credentials** - Store client credentials securely (environment variables or secrets management)
+✅ **Monitor Token Size** - JWT tokens are 10-15x larger than opaque (not usually an issue)
+✅ **Enable Logging** - Configure appropriate log levels for JWT verification
+
+### Production Configuration Example
+
+```yaml
+# docker-compose.yml (production)
+mcp-oauth:
+  image: ghcr.io/yourusername/nextcloud-mcp-server:latest
+  command: ["--transport", "streamable-http", "--oauth", "--port", "8001", "--oauth-token-type", "jwt"]
+  environment:
+    - NEXTCLOUD_HOST=https://nextcloud.example.com
+    - NEXTCLOUD_MCP_SERVER_URL=https://mcp.example.com
+    - NEXTCLOUD_PUBLIC_ISSUER_URL=https://nextcloud.example.com
+    - NEXTCLOUD_OIDC_CLIENT_ID=${JWT_CLIENT_ID}
+    - NEXTCLOUD_OIDC_CLIENT_SECRET=${JWT_CLIENT_SECRET}
+    - NEXTCLOUD_OIDC_SCOPES=openid profile email mcp:notes:read mcp:notes:write
+  ports:
+    - "8001:8001"
+```
+
+### Security Considerations
+
+**Token Storage:**
+- Never commit credentials to version control
+- Use environment variables or secrets management
+- Rotate client secrets periodically
+
+**Scope Configuration:**
+- Grant minimum necessary scopes to clients
+- Use read-only tokens for AI assistants that don't need write access
+- Review OAuth client list regularly
+
+**Network Security:**
+- Use HTTPS in production
+- Ensure issuer URL matches public URL
+- Configure proper CORS headers
+
+### Monitoring
+
+**Key Metrics:**
+- JWT verification success/failure rate
+- Scope challenge frequency (indicates clients with insufficient scopes)
+- Token validation latency
+- Tool execution by scope (identify unused scopes)
+
+**Log Patterns:**
+```bash
+# Success
+INFO JWT verified successfully for user: admin
+INFO ✅ Extracted scopes from access token: {'openid', 'profile', 'email', 'mcp:notes:read', 'mcp:notes:write'}
+
+# Failures
+WARNING JWT issuer validation failed: Invalid issuer
+WARNING Missing required scopes: mcp:notes:write
+```
+
+### Known Limitations
+
+1. **No Fine-Grained Scopes** - Only coarse `mcp:notes:read` and `mcp:notes:write` (not per-app scopes)
+2. **No Refresh Token Support** - Tokens must be reacquired when expired
+
+### Future Enhancements
+
+**Potential Improvements:**
+- Per-app scopes (`nc:notes:read`, `nc:calendar:write`)
+- Resource-level filtering (apply to MCP resources, not just tools)
+- Automatic scope discovery from decorated tools
+- Admin UI for scope management

+### Limited Scopes - Only Seeing Notes Tools
+
+**Symptoms**:
+- MCP client (e.g., Claude Code) successfully connects via OAuth
+- Only Notes tools are available (7 tools instead of 90+)
+- Token scopes show only `mcp:notes:read` and `mcp:notes:write`
+
+**Cause**: During the OAuth consent flow, the user only granted access to Notes scopes, or the client only requested those scopes.
+
+**Diagnosis**:
+
+Check what scopes the client has been granted:
+
+```bash
+# View registered clients and their allowed scopes
+php occ oidc:list | jq '.[] | select(.name | contains("Claude Code")) | {name, allowed_scopes}'
+```
+
+Look for the client's `allowed_scopes` field. If it's empty or only contains notes scopes, that's the issue.
+
+**Solution**:
+
+**Option 1: Delete Client and Reconnect** (Recommended for MCP clients)
+
+```bash
+# Find the client ID
+php occ oidc:list | jq '.[] | select(.name | contains("Claude Code")) | {name, client_id}'
+
+# Delete the client
+php occ oidc:delete <client_id>
+
+# Reconnect from Claude Code
+# This will trigger a new OAuth flow where you can grant all scopes
+```
+
+When reconnecting, you'll see a consent screen listing all available scopes. Make sure to approve all the scopes you want the client to access.
+
+**Option 2: Update Client Scopes via CLI**
+
+```bash
+# Update allowed scopes for an existing client
+php occ oidc:update <client_id> \
+  --allowed-scopes "openid profile email mcp:notes:read mcp:notes:write mcp:calendar:read mcp:calendar:write mcp:contacts:read mcp:contacts:write mcp:cookbook:read mcp:cookbook:write mcp:deck:read mcp:deck:write mcp:tables:read mcp:tables:write mcp:files:read mcp:files:write mcp:sharing:read mcp:sharing:write"
+
+# User will need to reconnect to get new token with updated scopes
+```
+
+**Verify Available Scopes**:
+
+Check what scopes the MCP server advertises:
+
+```bash
+curl http://localhost:8001/.well-known/oauth-protected-resource | jq '.scopes_supported'
+
+# Should show all 16 scope categories:
+# - openid
+# - mcp:notes:read, mcp:notes:write
+# - mcp:calendar:read, mcp:calendar:write
+# - mcp:contacts:read, mcp:contacts:write
+# - mcp:cookbook:read, mcp:cookbook:write
+# - mcp:deck:read, mcp:deck:write
+# - mcp:tables:read, mcp:tables:write
+# - mcp:files:read, mcp:files:write
+# - mcp:sharing:read, mcp:sharing:write
+```
+
+**Understanding Scope Filtering**:
+
+The MCP server dynamically filters tools based on the scopes in your access token:
+- Check server logs for: `✂️ JWT scope filtering: X/90 tools available for scopes: {...}`
+- This shows how many tools are visible vs total available
+- Each tool requires specific scopes (read and/or write)
+
+**Available Scope Categories**:
+
+| Scope Prefix | Nextcloud App | Read Operations | Write Operations |
+|--------------|---------------|-----------------|------------------|
+| `mcp:notes:*` | Notes | Get, search, list | Create, update, delete, append |
+| `mcp:calendar:*` | Calendar (CalDAV) | Get events, todos, calendars | Create/update/delete events, todos |
+| `mcp:contacts:*` | Contacts (CardDAV) | Get contacts, address books | Create/update/delete contacts |
+| `mcp:cookbook:*` | Cookbook | Get recipes, search | Create/update recipes |
+| `mcp:deck:*` | Deck | Get boards, cards | Create/update boards, cards |
+| `mcp:tables:*` | Tables | Get rows, tables | Create/update/delete rows |
+| `mcp:files:*` | Files (WebDAV) | List, read files | Upload, delete, move files |
+| `mcp:sharing:*` | Sharing | Get shares | Create/update shares |

+### 2. PKCE Support (RFC 7636)
 
-**Status**: 🟢 **PR Submitted** (Pending Review)
+**Status**: ✅ **Complete** (Merged Upstream)
 
 **Affected Component**: `oidc` app
 
-**Issue**: The OIDC discovery endpoint (`/.well-known/openid-configuration`) does not advertise PKCE support in the `code_challenge_methods_supported` field.
+**Issue**: The OIDC app lacked PKCE (Proof Key for Code Exchange) implementation per RFC 7636.
 
-**Why It Matters**:
-- MCP specification requires PKCE with S256 code challenge method
-- RFC 8414 states that absence of `code_challenge_methods_supported` means PKCE is **not supported**
-- Some MCP clients may reject providers without proper PKCE advertisement
+**Resolution**: Full PKCE support has been implemented and merged upstream into the `oidc` app:
 
-**Current Behavior**:
-- PKCE **functionally works** (the OIDC app accepts and validates PKCE)
-- PKCE just isn't **advertised** in discovery metadata
+**Authorization Endpoint** (`/authorize`):
+- Accepts `code_challenge` and `code_challenge_method` parameters
+- Validates code_challenge format (43-128 characters, unreserved chars only)
+- Supports both `S256` (SHA-256) and `plain` challenge methods
+- Stores challenge and method in database for later verification
 
-**Recommended Fix**: Update `oidc` app to include:
+**Token Endpoint** (`/token`):
+- Accepts `code_verifier` parameter
+- Verifies code_verifier against stored code_challenge using proper algorithm
+- Uses constant-time comparison to prevent timing attacks
+- Enforces code_verifier requirement when PKCE was used in authorization
+
+**Discovery Document**:
 ```json
 {
-  "code_challenge_methods_supported": ["S256"]
+  "code_challenge_methods_supported": ["S256", "plain"]
 }
 ```
 
-**Workaround**: The MCP server implements PKCE validation and logs a warning if not advertised. Functionality still works.
+**Database**:
+- New columns: `code_challenge` and `code_challenge_method` in `oc_oauth2_access_tokens`
+- Migration included for existing installations

+# Testing Client Sessions Architecture
+
+## Overview
+
+This document compares different approaches to managing MCP client sessions in integration tests, addressing the fundamental incompatibility between pytest-asyncio's fixture management and anyio's structured concurrency requirements.
+
+## The Problem
+
+When using pytest-asyncio with anyio-based libraries (like the MCP Python SDK), session-scoped async generator fixtures encounter a fundamental issue:
+
+1. **pytest-asyncio** runs fixture teardown in a **new asyncio task** using `runner.run()`
+2. **anyio** requires that cancel scopes be entered and exited in the **same task**
+3. This causes `RuntimeError: Attempted to exit cancel scope in a different task than it was entered in`
+
+This is a **known limitation** documented in the anyio project and is not a bug in either pytest-asyncio or anyio, but rather an inherent incompatibility between their design philosophies.
+
+## Solution Comparison
+
+### Solution 1: Native Async Context Managers with Surgical Exception Handling ✅ **IMPLEMENTED**
+
+**Approach**: Use native `async with` statements for clean code structure, but add targeted exception handling at the pytest fixture level to handle the expected teardown errors.
+
+**Implementation**:
+
+```python
+async def create_mcp_client_session(
+    url: str,
+    token: str | None = None,
+    client_name: str = "MCP",
+) -> AsyncGenerator[ClientSession, Any]:
+    """Uses native async context managers for clean LIFO cleanup."""
+    headers = {"Authorization": f"Bearer {token}"} if token else None
+
+    async with streamablehttp_client(url, headers=headers) as (read_stream, write_stream, _):
+        async with ClientSession(read_stream, write_stream) as session:
+            await session.initialize()
+            yield session
+
+@pytest.fixture(scope="session")
+async def nc_mcp_client() -> AsyncGenerator[ClientSession, Any]:
+    """Fixture with surgical exception handling for pytest-asyncio incompatibility."""
+    try:
+        async for session in create_mcp_client_session(
+            url="http://localhost:8000/mcp", client_name="Basic MCP"
+        ):
+            yield session
+    except RuntimeError as e:
+        # Only catch the specific expected error during pytest teardown
+        if "cancel scope" in str(e) and "different task" in str(e):
+            logger.debug(f"Ignoring expected pytest-asyncio teardown issue: {e}")
+        else:
+            # Unexpected RuntimeError - re-raise to fail the test
+            raise
+```
+
+**Pros**:
+- ✅ Clean, idiomatic code using native Python context managers
+- ✅ Exception handling is surgical - only catches the specific expected error
+- ✅ Unexpected errors still propagate and fail tests
+- ✅ Can use session-scoped fixtures for performance
+- ✅ Easy to understand and maintain
+- ✅ Minimal code changes from original implementation
+- ✅ No external dependencies required
+
+**Cons**:
+- ⚠️ Still requires exception suppression (though targeted)
+- ⚠️ String-based exception matching is somewhat fragile
+- ⚠️ Must apply the pattern to each session-scoped fixture
+- ⚠️ Doesn't solve the root cause
+
+**Verdict**: **Recommended** - Best balance of code clarity, maintainability, and pragmatism.
+
+---
+
+### Solution 2: Task-Isolated Fixtures
+
+**Approach**: Run each fixture's client session in an isolated anyio task group, allowing independent cleanup without cross-fixture interference.
+
+**Implementation**:
+
+```python
+@pytest.fixture(scope="session")
+async def nc_mcp_client() -> AsyncGenerator[ClientSession, Any]:
+    """Fixture with task isolation for clean teardown."""
+    import anyio
+
+    session_holder = {"session": None}
+
+    async def create_and_hold_session():
+        """Runs in isolated task - creates session and keeps it alive."""
+        async with streamablehttp_client("http://localhost:8000/mcp") as (read_stream, write_stream, _):
+            async with ClientSession(read_stream, write_stream) as session:
+                await session.initialize()
+                session_holder["session"] = session
+
+                # Keep session alive until cancelled
+                try:
+                    await anyio.sleep_forever()
+                except anyio.get_cancelled_exc_class():
+                    pass  # Expected cancellation
+
+    async with anyio.create_task_group() as tg:
+        tg.start_soon(create_and_hold_session)
+
+        # Wait for session to be ready
+        while session_holder["session"] is None:
+            await anyio.sleep(0.1)
+
+        yield session_holder["session"]
+
+        # Task group cancellation ensures clean LIFO cleanup
+        tg.cancel_scope.cancel()
+```
+
+**Pros**:
+- ✅ No exception suppression needed
+- ✅ Each fixture has its own isolated task scope
+- ✅ More theoretically correct approach
+- ✅ Can use session-scoped fixtures
+
+**Cons**:
+- ❌ Significantly more complex code
+- ❌ Harder to understand for developers unfamiliar with anyio
+- ❌ Requires understanding of task groups and cancel scopes
+- ❌ More boilerplate per fixture
+- ❌ Still doesn't solve the fundamental pytest-asyncio incompatibility
+- ❌ Polling for session readiness is inelegant
+- ❌ Higher cognitive overhead for maintenance
+
+**Verdict**: **Not Recommended** - Complexity outweighs benefits. Consider only if exception handling is completely unacceptable.
+
+---
+
+### Solution 3: Function-Scoped Fixtures with Nested Context Managers
+
+**Approach**: Change fixtures to function scope and rely on Python's context manager nesting for guaranteed LIFO cleanup.
+
+**Implementation**:
+
+```python
+@pytest.fixture(scope="function")  # Changed from session
+async def nc_mcp_client() -> AsyncGenerator[ClientSession, Any]:
+    """Function-scoped fixture with natural LIFO cleanup."""
+    async with streamablehttp_client("http://localhost:8000/mcp") as (read_stream, write_stream, _):
+        async with ClientSession(read_stream, write_stream) as session:
+            await session.initialize()
+            yield session
+
+# For tests needing multiple clients:
+@pytest.fixture(scope="function")
+async def multi_mcp_clients() -> AsyncGenerator[tuple[ClientSession, ClientSession], Any]:
+    """Multiple clients with guaranteed LIFO cleanup through nesting."""
+    async with streamablehttp_client("http://localhost:8000/mcp") as (read1, write1, _):
+        async with ClientSession(read1, write1) as session1:
+            await session1.initialize()
+
+            async with streamablehttp_client("http://localhost:8001/mcp") as (read2, write2, _):
+                async with ClientSession(read2, write2) as session2:
+                    await session2.initialize()
+                    yield session1, session2
+    # Cleanup: session2 -> stream2 -> session1 -> stream1 (LIFO guaranteed)
+```
+
+**Pros**:
+- ✅ No exception handling needed
+- ✅ Simplest to understand
+- ✅ Natural LIFO cleanup through Python's context managers
+- ✅ Each test gets fresh clients (better isolation)
+- ✅ No workarounds or hacks required
+
+**Cons**:
+- ❌ Significantly slower tests (new clients per test)
+- ❌ Cannot share client state across tests
+- ❌ More resource intensive
+- ❌ Higher overhead for test suite execution
+- ❌ May not be practical for expensive fixtures (e.g., OAuth tokens)
+- ❌ Nested context managers become unwieldy with many clients
+
+**Verdict**: **Good Alternative** - Consider for specific fixtures where session scope isn't critical, or for new test files where performance isn't a concern.
+
+---
+
+### Solution 4: Use pytest-trio Instead of pytest-asyncio (Future)
+
+**Approach**: Replace pytest-asyncio with pytest-trio, which was designed with structured concurrency in mind.
+
+**Implementation**:
+
+```python
+# pyproject.toml
+[tool.pytest.ini_options]
+# Remove: asyncio_mode = "auto"
+# Add: trio_mode = "auto"
+
+# Fixtures work naturally with trio
+@pytest.fixture(scope="session")
+async def nc_mcp_client() -> AsyncGenerator[ClientSession, Any]:
+    async with streamablehttp_client("http://localhost:8000/mcp") as (read, write, _):
+        async with ClientSession(read, write) as session:
+            await session.initialize()
+            yield session
+```
+
+**Pros**:
+- ✅ No workarounds needed
+- ✅ Designed for structured concurrency
+- ✅ Theoretically cleanest solution
+- ✅ Can use session-scoped fixtures naturally
+
+**Cons**:
+- ❌ Requires switching from asyncio to trio backend
+- ❌ Major refactoring required
+- ❌ May break existing code that assumes asyncio
+- ❌ Dependency changes throughout project
+- ❌ Team needs to learn trio ecosystem
+- ❌ Less ecosystem support than asyncio
+
+**Verdict**: **Not Practical** - Too disruptive for existing projects. Consider only for greenfield projects or major rewrites.

+| Solution 4 (pytest-trio) | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐ |
+
+## Implementation Details
+
+### What Changed in Solution 1
+
+1. **`create_mcp_client_session` function** (conftest.py:61-110):
+   - Replaced manual `__aenter__`/`__aexit__` calls with native `async with` statements
+   - Removed blanket exception suppression from cleanup logic
+   - Added clear documentation about LIFO cleanup order
+   - Simplified from ~60 lines to ~40 lines
+
+2. **Session-scoped MCP client fixtures** (conftest.py:148-1269):
+   - Added targeted exception handling wrapper
+   - Only catches specific "cancel scope" + "different task" RuntimeError
+   - All other exceptions propagate normally
+   - Applied to: `nc_mcp_client`, `nc_mcp_oauth_client`, `alice_mcp_client`, `bob_mcp_client`, `charlie_mcp_client`, `diana_mcp_client`
+
+3. **Documentation**:
+   - Added comprehensive docstrings explaining the workaround
+   - Referenced MCP SDK issue #577 for context
+   - Documented why this is necessary and not a bug
+
+### Benefits of This Implementation
+
+1. **Clean Core Logic**: The `create_mcp_client_session` function is now clean, idiomatic Python with no workarounds
+2. **Isolated Workaround**: Exception handling is confined to pytest fixture level where the issue actually occurs
+3. **Surgical Exception Handling**: Only catches the specific expected error, not all RuntimeErrors
+4. **Performance**: Maintains session-scoped fixtures for fast test execution
+5. **Maintainability**: Easy to understand and modify
+6. **Safety**: Real errors still cause test failures
+

+## Recommendations
+
+### For This Project: Solution 1 ✅
+
+The implemented solution (Solution 1) is the best fit because:
+- Minimal disruption to existing tests
+- Clean, maintainable code
+- Good performance with session-scoped fixtures
+- Targeted exception handling that doesn't hide real errors
+
+### For New Test Files: Consider Solution 3
+
+For new test files where performance isn't critical, consider using function-scoped fixtures (Solution 3):
+- No workarounds needed
+- Perfect code clarity
+- Better test isolation
+
+### For Greenfield Projects: Consider Solution 4
+
+For new projects starting from scratch, consider pytest-trio instead of pytest-asyncio:
+- Native structured concurrency support
+- No workarounds needed
+- Better alignment with modern async Python patterns

+
+## Appendix: Why Can't This Be Fixed Upstream?
+
+The incompatibility cannot be "fixed" in either pytest-asyncio or anyio without breaking their core design:
+
+1. **pytest-asyncio** needs to manage fixture lifecycle across different scopes, requiring separate task creation for cleanup
+2. **anyio** enforces structured concurrency guarantees by requiring same-task cancel scope entry/exit
+3. These requirements are fundamentally incompatible
+
+The maintainers of both projects are aware of this issue, and it's considered an acceptable trade-off given their respective design goals. The recommended approach is to handle it at the application level, as we've done here.

+# Testing OIDC Consent Feature
+
+This guide explains how to test the OIDC consent feature using the development version of the OIDC app mounted into the Docker environment.
+
+## Setup
+
+### Volume Mount Configuration
+
+The development OIDC app is mounted from `~/Software/oidc` into the container at `/opt/apps/oidc`:
+
+```yaml
+# docker-compose.yml
+volumes:
+  - ../Software/oidc:/opt/apps/oidc:ro
+```
+
+**Why mount outside `/var/www/html/`?**
+- The Nextcloud container uses `rsync` to initialize `/var/www/html/` from the image
+- Mounting inside that path causes conflicts (rsync tries to delete mounted directories)
+- Mounting to `/opt/apps/oidc` avoids rsync entirely
+- Nextcloud supports multiple app directories via the `apps_paths` configuration
+
+**How multiple app paths work:**
+- Nextcloud can load apps from multiple directories
+- The post-installation hook registers `/opt/apps` as an additional app directory (index 2)
+- Apps in default paths (index 0 and 1) are still available
+- All directories are scanned for apps, but `/opt/apps` is read-only
+
+This setup allows you to:
+- Test changes without rebuilding containers
+- Avoid needing npm/node in the container (JS already built on host)
+- Iterate quickly on development
+- Install other Nextcloud apps normally (custom_apps remains writable)
+
+### How It Works
+
+1. **Mount Development App**: Docker mounts `~/Software/oidc` to `/opt/apps/oidc` (outside Nextcloud's path)
+2. **Register App Path**: The `10-install-oidc-app.sh` hook configures `/opt/apps` as an additional app directory
+3. **Enable App**: The hook enables the OIDC app from `/opt/apps/oidc`
+4. **Run Migrations**: Nextcloud detects pending migrations and runs them automatically
+5. **Configure OIDC**: Dynamic client registration and PKCE are enabled
+
+## Starting the Stack
+
+```bash
+cd ~/Projects/nextcloud-mcp-server
+
+# Start fresh (recommended for first test)
+docker compose down -v
+docker compose up -d
+
+# Wait for initialization (check logs)
+docker compose logs -f app
+```
+
+The post-installation hooks will:
+1. Configure custom_apps path (already done)
+2. Enable OIDC app from mounted directory
+3. Run database migrations (including consent table creation)
+4. Configure OIDC settings
+
+## Verifying Installation
+
+### Before Container Restart
+
+Before running `docker compose up -d`, the consent feature will NOT be active:
+- ❌ No `oc_oidc_user_consents` table in database
+- ❌ Migration 0015 not applied yet
+- ❌ ConsentController class not loaded
+- ❌ Consent routes not registered
+
+You can verify this with:
+```bash
+# Check migrations applied (should stop at 0014)
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT version FROM oc_migrations WHERE app = 'oidc' ORDER BY version DESC LIMIT 3;" nextcloud
+
+# Check for consent table (should return empty)
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SHOW TABLES LIKE 'oc_oidc_user_consents';" nextcloud
+```
+
+### After Container Restart
+
+After `docker compose up -d` with the mounted OIDC directory, the consent feature should be active:
+- ✅ `oc_oidc_user_consents` table exists
+- ✅ Migration 0015 (Version0015Date20251123100100) applied
+- ✅ ConsentController routes registered
+- ✅ Consent screen appears during OAuth flows
+
+### Check App Status
+
+```bash
+docker compose exec app php occ app:list | grep -A 2 oidc
+```
+
+Expected output:
+```
+  - oidc: 1.10.0 (enabled)
+```
+
+### Verify App Paths Configuration
+
+Verify that `/opt/apps` is registered as an additional app directory:
+
+```bash
+# Check configured app paths
+docker compose exec app php occ config:system:get apps_paths
+
+# Verify the mount is accessible
+docker compose exec app ls -la /opt/apps/oidc/
+
+# Verify custom_apps is writable (for normal app installation)
+docker compose exec -u www-data app touch /var/www/html/custom_apps/.test && echo "✅ custom_apps is writable" || echo "❌ custom_apps NOT writable"
+docker compose exec app rm -f /var/www/html/custom_apps/.test
+```
+
+Expected: Output should show multiple app paths including index 2 (/opt/apps).
+
+### Verify Consent Files
+
+```bash
+# Check controller exists in mounted location
+docker compose exec app ls -la /opt/apps/oidc/lib/Controller/ConsentController.php
+
+# Check Vue component exists
+docker compose exec app ls -la /opt/apps/oidc/src/Consent.vue
+
+# Check built JS exists
+docker compose exec app ls -lh /opt/apps/oidc/js/oidc-consent.js
+```
+
+### Verify Database Migration
+
+**Note**: These checks will only pass after restarting containers with the mounted OIDC app.
+
+```bash
+# Check if consent table exists
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SHOW TABLES LIKE 'oc_oidc_user_consents';"
+
+# Check table structure
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "DESCRIBE oc_oidc_user_consents;"
+
+# Verify migration 0015 was applied
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT app, version FROM oc_migrations WHERE app = 'oidc' AND version LIKE '%0015%';"
+```
+
+Expected table structure:
+- id: int(10) unsigned, auto_increment, primary key
+- user_id: varchar(256), not null
+- client_id: int(10) unsigned, not null
+- scopes_granted: varchar(512), not null
+- created_at: int(10) unsigned, not null
+- updated_at: int(10) unsigned, not null
+- expires_at: int(10) unsigned, nullable
+
+### Verify Routes
+
+```bash
+docker compose exec app php occ router:list | grep consent
+```
+
+Expected output:
+```
+oidc.Consent.show        GET    apps/oidc/consent
+oidc.Consent.grant       POST   apps/oidc/consent/grant
+oidc.Consent.deny        POST   apps/oidc/consent/deny
+```
+
+## Testing the Consent Flow
+
+### 1. Create an OAuth Client
+
+The JWT client is automatically created by the post-installation hooks:
+
+```bash
+# Check if JWT client exists
+docker compose exec app cat /var/www/html/.oauth-jwt/nextcloud_oauth_client.json
+```
+
+### 2. Initiate Authorization Flow
+
+You can test using the MCP OAuth container or manually:
+
+**Option A: Using MCP OAuth container**
+```bash
+# The mcp-oauth container will trigger the OAuth flow
+docker compose logs -f mcp-oauth
+```
+
+**Option B: Manual browser test**
+1. Get client_id from the JWT client JSON
+2. Visit in browser:
+```
+http://localhost:8080/apps/oidc/authorize?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=http://localhost:8001/oauth/callback&scope=openid+profile+email+mcp:notes:read+mcp:notes:write&state=test123
+```
+
+### 3. Expected Behavior
+
+**First Authorization:**
+1. User logs in (if not already authenticated)
+2. **Consent screen appears** with:
+   - Application name: "Nextcloud MCP Server JWT"
+   - List of requested scopes with descriptions:
+     - ✓ Basic authentication (openid) - required, cannot deselect
+     - ✓ Profile information (profile)
+     - ✓ Email address (email)
+     - ✓ mcp:notes:read (custom scope, shown as-is)
+     - ✓ mcp:notes:write (custom scope, shown as-is)
+   - "Allow" and "Deny" buttons
+3. User selects scopes and clicks "Allow"
+4. Authorization proceeds with selected scopes
+5. Consent is stored in database
+
+**Subsequent Authorizations:**
+- Same scopes → No consent screen (uses stored consent)
+- Different scopes → Consent screen appears again
+- If user clicks "Deny" → Returns `error=access_denied` to client
+
+### 4. Verify Consent Stored
+
+After granting consent:
+
+```bash
+# View all stored consents with formatted timestamps
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "
+SELECT
+    user_id,
+    client_id,
+    scopes_granted,
+    FROM_UNIXTIME(created_at) as created,
+    FROM_UNIXTIME(updated_at) as updated,
+    FROM_UNIXTIME(expires_at) as expires
+FROM oc_oidc_user_consents;
+" nextcloud
+
+# Or for a compact view:
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT * FROM oc_oidc_user_consents;" nextcloud
+```
+
+## Troubleshooting
+
+### Consent Screen Not Appearing
+
+**Check browser console** (F12 → Console tab):
+```
+# Look for JS errors like:
+Failed to load resource: js/oidc-consent.js
+```
+
+**Check Nextcloud logs:**
+```bash
+docker compose exec app tail -f /var/www/html/data/nextcloud.log | grep -i consent
+```
+
+**Verify JS file loaded:**
+```bash
+# Check file exists and has correct size (~73KB)
+docker compose exec app ls -lh /opt/apps/oidc/js/oidc-consent.js
+```
+
+**Clear Nextcloud caches:**
+```bash
+docker compose exec app php occ maintenance:repair
+docker compose restart app
+```
+
+### Migration Didn't Run
+
+**Check which migrations have been applied:**
+```bash
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT app, version FROM oc_migrations WHERE app = 'oidc' ORDER BY version;" nextcloud
+```
+
+Expected to see `Version0015Date20251123100100` in the list.
+
+**Manually trigger migrations:**
+```bash
+# Disable and re-enable app (triggers all pending migrations)
+docker compose exec app php occ app:disable oidc
+docker compose exec app php occ app:enable oidc
+
+# Verify migration 0015 was applied
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT version FROM oc_migrations WHERE app = 'oidc' AND version LIKE '%0015%';" nextcloud
+```
+
+### Routes Not Registered
+
+If `router:list` doesn't show consent routes:
+
+```bash
+# The autoloader might not have picked up new classes
+# Restart the container
+docker compose restart app
+
+# Wait for it to be ready
+sleep 10
+
+# Try again
+docker compose exec app php occ router:list | grep consent
+```
+
+If still not working, check if ConsentController is accessible:
+```bash
+docker compose exec app php -r "
+require_once '/var/www/html/lib/base.php';
+\$class = 'OCA\\OIDCIdentityProvider\\Controller\\ConsentController';
+if (class_exists(\$class)) {
+    echo \"Class exists\n\";
+} else {
+    echo \"Class not found\n\";
+}
+"
+```
+
+## Making Changes
+
+### Frontend Changes (Vue.js)
+
+1. Edit source file on host:
+```bash
+cd ~/Software/oidc
+# Edit src/Consent.vue
+```
+
+2. Rebuild JS:
+```bash
+npm run build
+```
+
+3. Refresh browser (container sees changes immediately via volume mount at /opt/apps/oidc)
+
+### Backend Changes (PHP)
+
+1. Edit files on host:
+```bash
+cd ~/Software/oidc
+# Edit lib/Controller/ConsentController.php or other PHP files
+```
+
+2. Changes are immediately visible (PHP is interpreted, no build step)
+
+3. For new classes or major changes, restart container:
+```bash
+docker compose restart app
+```
+
+### Database Schema Changes
+
+If you modify the migration:
+
+```bash
+# Changes won't be picked up if migration already ran
+# Need to recreate the database:
+docker compose down -v  # Removes volumes
+docker compose up -d    # Fresh start with clean DB
+```
+
+## Cleanup
+
+### Reset Everything
+
+```bash
+cd ~/Projects/nextcloud-mcp-server
+docker compose down -v
+```
+
+This removes:
+- All containers
+- Database volume (all data)
+- OAuth client credentials
+
+### Keep Data, Restart App
+
+```bash
+docker compose restart app
+```
+
+This preserves:
+- Database (consents, clients, users)
+- OAuth client credentials
+
+## Development Workflow Summary
+
+1. **Make changes** in `~/Software/oidc`
+2. **Build JS** if you changed Vue files: `npm run build`
+3. **Test immediately** - refresh browser or restart container
+4. **No need** to rebuild Docker images or reinstall app
+5. **Iterate quickly** with instant feedback
+
+## Production Deployment
+
+When ready to deploy:
+
+1. **Create patch file** (already done):
+   ```bash
+   cd ~/Software/oidc
+   git format-patch master --stdout > user-consent-feature.patch
+   ```
+
+2. **Test patch** in clean environment:
+   ```bash
+   # In a production-like environment
+   cd /path/to/production/oidc
+   git apply user-consent-feature.patch
+   npm install
+   npm run build
+   php occ app:disable oidc
+   php occ app:enable oidc
+   ```
+
+3. **Verify migration** runs automatically on app enable
+
+4. **Submit pull request** to upstream repository

+# OAuth Multi-User Load Testing Framework
+
+Comprehensive multi-user benchmarking system for testing OAuth-authenticated Nextcloud MCP server with realistic collaborative workflows.
+
+## Quick Start
+
+```bash
+# 1. Ensure docker-compose is running
+docker-compose up -d
+
+# 2. Run a benchmark with 2 users for 30 seconds
+uv run python -m tests.load.oauth_benchmark --users 2 --duration 30
+
+# 3. Clean up test users (IMPORTANT - always run after benchmark)
+uv run python -m tests.load.cleanup_loadtest_users
+
+# Optional: Verify cleanup
+uv run python -m tests.load.cleanup_loadtest_users --dry-run
+```
+
+## Overview
+
+This framework extends the basic load testing infrastructure to support:
+- **Multiple OAuth-authenticated users** running concurrently
+- **Coordinated workflows** spanning multiple users (sharing, collaboration, permissions)
+- **Per-user metrics** tracking individual user performance
+- **Workflow-specific metrics** measuring cross-user operation latencies
+- **Realistic scenarios** mimicking actual user collaboration patterns
+- **Concurrent user creation** - all users created and authenticated in parallel for fast setup
+
+## Architecture
+
+### Components

+├── oauth_benchmark.py     # Main CLI entry point
+└── README_OAUTH.md        # This file
+```
+
+### Key Classes
+
+**OAuthUserPool** (`oauth_pool.py`)
+- Manages N OAuth-authenticated users
+- Handles token acquisition and storage
+- Creates and manages MCP sessions per user
+- Tracks per-user operation statistics
+
+**UserSessionWrapper** (`oauth_pool.py`)
+- Wraps MCP ClientSession for a specific user
+- Automatic operation tracking
+- Convenient tool/resource access methods
+
+**Workflow** (`oauth_workloads.py`)
+- Base class for multi-user coordinated workflows
+- Step-by-step execution with timing
+- Comprehensive error handling and reporting
+
+**OAuthBenchmarkMetrics** (`oauth_metrics.py`)
+- Per-user operation counts and latencies
+- Workflow completion rates and timings
+- Baseline operation statistics
+- Detailed reporting and JSON export
+
+## Available Workflows
+
+### 1. NoteShareWorkflow
+**Scenario**: Alice creates a note and shares it with Bob, who then reads it.
+
+**Steps**:
+1. User A creates a note
+2. User A shares note with User B (read-only permissions)
+3. User B lists their shared notes (measures propagation delay)
+4. User B reads the shared note
+
+**Metrics**: Creation latency, share propagation time, read latency
+
+### 2. CollaborativeEditWorkflow
+**Scenario**: Multiple users concurrently edit the same note.
+
+**Steps**:
+1. Owner creates a note
+2. All users read the note simultaneously
+3. All users append content concurrently
+4. Owner verifies final state
+
+**Metrics**: Concurrent read latency, concurrent write conflicts, final state consistency
+
+### 3. FileShareAndDownloadWorkflow
+**Scenario**: Alice uploads a file, shares it with Bob, who then downloads it.
+
+**Steps**:
+1. User A creates a file via WebDAV
+2. User A shares file with User B (read-only)
+3. User B lists their shares
+4. User B downloads the file
+
+**Metrics**: Upload latency, share creation, download latency
+
+### 4. MixedOAuthWorkload
+**Distribution**:
+- 50% Baseline operations (individual user CRUD)
+- 30% Note sharing workflows
+- 15% Collaborative editing workflows
+- 5% File sharing workflows
+
+## Usage
+
+### Basic Usage
+
+```bash
+# 4 users, 60-second test with mixed workload
+uv run python -m tests.load.oauth_benchmark --users 4 --duration 60
+
+# 10 users, 5-minute test
+uv run python -m tests.load.oauth_benchmark -u 10 -d 300
+
+# Export results to JSON
+uv run python -m tests.load.oauth_benchmark -u 5 -d 120 --output results.json
+```
+
+### Advanced Options
+
+```bash
+# Sharing-focused workload
+uv run python -m tests.load.oauth_benchmark --workload sharing -u 8 -d 180
+
+# Collaborative editing workload
+uv run python -m tests.load.oauth_benchmark --workload collaboration -u 6 -d 120
+
+# Baseline operations only (no workflows)
+uv run python -m tests.load.oauth_benchmark --workload baseline -u 10 -d 60
+
+# Verbose logging for debugging
+uv run python -m tests.load.oauth_benchmark -u 2 -d 30 --verbose
+```
+
+### CLI Options
+
+| Option | Short | Default | Description |
+|--------|-------|---------|-------------|
+| `--users` | `-u` | 2 | Number of concurrent users (dynamically created) |
+| `--duration` | `-d` | 30.0 | Test duration in seconds |
+| `--warmup` | `-w` | 5.0 | Warmup period before metrics collection (seconds) |
+| `--url` | | `http://localhost:8001/mcp` | MCP OAuth server URL |
+| `--output` | `-o` | None | JSON output file path |
+| `--workload` | | `mixed` | Workload type: mixed, sharing, collaboration, baseline |
+| `--user-prefix` | | `loadtest` | Prefix for dynamically created usernames |
+| `--cleanup/--no-cleanup` | | `cleanup` | Delete created users after benchmark |
+| `--browser` | | `chromium` | Playwright browser: firefox, chromium, webkit |
+| `--headed` | | False | Run browser in headed mode (visible window) |
+| `--verbose` | `-v` | False | Enable verbose logging |
+
+## Test User Creation
+
+The framework **dynamically creates test users** on-demand with OAuth authentication:
+
+- **Naming**: Users are created with the pattern `{prefix}_user_{n}` (default: `loadtest_user_1`, `loadtest_user_2`, etc.)
+- **Customization**: Use `--user-prefix` to change the prefix (e.g., `--user-prefix mytest` → `mytest_user_1`)
+- **Scalability**: No limit on user count - create as many concurrent users as your system can handle
+- **Credentials**: Each user gets a randomly generated secure password
+- **OAuth Tokens**: All users authenticate via automated OAuth flow using Playwright
+- **Cleanup**: Users are automatically deleted after the benchmark (disable with `--no-cleanup`)
+
+**Example**: Running `--users 5` creates:
+- `loadtest_user_1` (Display: Load Test User 1, Email: loadtest_user_1@benchmark.local)
+- `loadtest_user_2` (Display: Load Test User 2, Email: loadtest_user_2@benchmark.local)
+- `loadtest_user_3` (Display: Load Test User 3, Email: loadtest_user_3@benchmark.local)
+- `loadtest_user_4` (Display: Load Test User 4, Email: loadtest_user_4@benchmark.local)
+- `loadtest_user_5` (Display: Load Test User 5, Email: loadtest_user_5@benchmark.local)

+
+## Implementation Status
+
+### ✅ Completed Components
+
+**Framework:**
+- OAuth user pool management with dynamic user creation
+- User session wrappers with automatic tracking
+- Workflow base classes and framework
+- 3 example workflows (note share, collaborative edit, file share)
+- Enhanced metrics with per-user and workflow tracking
+- CLI interface with multiple workload options
+- Comprehensive reporting (console + JSON)
+
+**OAuth Integration:**
+- ✅ Playwright browser automation for OAuth login
+- ✅ OAuth callback server for auth code capture
+- ✅ Token exchange with OIDC provider
+- ✅ OAuth token injection into MCP sessions via Authorization headers
+- ✅ Cancel scope error handling for reliable cleanup
+- ✅ Dynamic user creation and deletion via Nextcloud Users API
+
+**Implementation Details:**
+The benchmark now successfully:
+1. Creates Nextcloud users dynamically with unique passwords
+2. Acquires OAuth tokens via automated Playwright browser flows
+3. Creates MCP client sessions with proper `Authorization: Bearer {token}` headers
+4. Executes coordinated multi-user workflows
+5. Tracks per-user and per-workflow metrics
+6. Provides standalone cleanup utility for test users
+
+**Key Fix (oauth_pool.py:163-164)**:
+```python
+# Pass OAuth token as Authorization header
+headers = {"Authorization": f"Bearer {profile.token}"}
+streamable_context = streamablehttp_client(mcp_url, headers=headers)
+```
+
+## Creating Custom Workflows
+
+### Example: Permission Escalation Workflow
+
+```python
+class PermissionEscalationWorkflow(Workflow):
+    """Test sharing permission changes."""
+
+    def __init__(self):
+        super().__init__("permission_escalation")
+
+    async def execute(self, users: list[UserSessionWrapper]) -> WorkflowResult:
+        self.start_time = time.time()
+
+        if len(users) < 2:
+            return self._finish(False, error="Requires 2+ users")
+
+        owner, collaborator = users[0], users[1]
+
+        # Step 1: Owner creates note
+        create_result = await self._execute_step(
+            "create_note",
+            owner,
+            lambda: owner.call_tool("nc_notes_create_note", {...})
+        )
+
+        # Step 2: Share read-only
+        await self._execute_step(
+            "share_readonly",
+            owner,
+            lambda: owner.call_tool("nc_share_create", {
+                "permissions": 1  # Read-only
+            })
+        )
+
+        # Step 3: Upgrade to edit permissions
+        await self._execute_step(
+            "upgrade_permissions",
+            owner,
+            lambda: owner.call_tool("nc_share_update", {
+                "permissions": 15  # Read+update+create+delete
+            })
+        )
+
+        # Step 4: Collaborator edits
+        await self._execute_step(
+            "collaborator_edit",
+            collaborator,
+            lambda: collaborator.call_tool("nc_notes_update_note", {...})
+        )
+
+        return self._finish(success=True)
+```
+
+### Registering Custom Workflows
+
+```python
+# In oauth_workloads.py
+class MixedOAuthWorkload:
+    def __init__(self, users: list[UserSessionWrapper]):
+        self.users = users
+        self.workflows = {
+            "note_share": NoteShareWorkflow(),
+            "collaborative_edit": CollaborativeEditWorkflow(),
+            "file_share": FileShareAndDownloadWorkflow(),
+            "permission_escalation": PermissionEscalationWorkflow(),  # Add your workflow
+        }
+```
+
+## Performance Expectations
+
+### Baseline Performance (basic auth, from existing benchmarks)
+- **Throughput**: 50-200 RPS for mixed workload
+- **Latency**: p50 <100ms, p95 <500ms, p99 <1000ms
+
+### OAuth Multi-User Expectations
+- **Lower throughput**: ~30-60% of baseline due to:
+  - OAuth token validation overhead
+  - Cross-user synchronization delays
+  - Workflow coordination overhead
+- **Higher p99 latency**: Due to workflow step dependencies
+- **Focus**: End-to-end workflow completion time more important than raw RPS
+
+### Common Bottlenecks
+1. **OAuth token validation**: Per-request overhead
+2. **Share propagation**: Time for shares to become visible to recipients
+3. **Concurrent edit conflicts**: ETags and conflict resolution
+4. **Permission checks**: Cross-user access validation
+
+## Best Practices
+
+1. **Start Small**: Begin with 2-3 users to validate workflows
+2. **Monitor Errors**: Watch for permission errors and conflicts
+3. **Adjust Delays**: Tune sleep delays between operations based on server response
+4. **Profile Workflows**: Use step latencies to identify bottlenecks
+5. **Export Results**: Always export to JSON for historical comparison
+
+## Performance Optimizations
+
+### Concurrent User Creation
+
+The benchmark creates and authenticates users **concurrently** for maximum performance:
+
+**Step 5: User Creation & OAuth Authentication**
+- All N users are created in parallel using `asyncio.gather()`
+- Each user runs through the full OAuth flow simultaneously
+- Multiple Playwright browser contexts operate independently
+
+**Step 6: MCP Session Creation**
+- All user sessions are created concurrently
+- OAuth tokens passed as Authorization headers to each session
+
+**Performance Impact:**
+- **Sequential** (old): ~10-12s per user → 40-48s for 4 users
+- **Concurrent** (new): ~12-15s total for 4 users (3-4x speedup!)
+
+Example output showing concurrent execution:
+```
+Step 5/6: Creating 4 users and acquiring OAuth tokens...
+(Running concurrently for faster setup)
+
+  [1/4] Creating user 'loadtest_user_1'...
+  [2/4] Creating user 'loadtest_user_2'...
+  [3/4] Creating user 'loadtest_user_3'...
+  [4/4] Creating user 'loadtest_user_4'...
+  ✓ User 'loadtest_user_4' authenticated
+  ✓ User 'loadtest_user_2' authenticated
+  ✓ User 'loadtest_user_1' authenticated
+  ✓ User 'loadtest_user_3' authenticated
+
+✓ Successfully created and authenticated 4 users
+```
+
+**Implementation** (oauth_benchmark.py:402-437):
+```python
+# Create tasks for all users
+tasks = [
+    create_user_task(i, browser, callback_server.auth_states)
+    for i in range(num_users)
+]
+# Run all concurrently
+results = await asyncio.gather(*tasks, return_exceptions=True)
+```
+
+## Cleanup
+
+**Important**: Due to asyncio scoping issues with the MCP client library, automatic cleanup in the benchmark's finally block may not execute reliably. Always use the cleanup utility after running benchmarks.
+
+### Cleanup Utility (Recommended)
+
+Use the cleanup utility to remove test users:
+
+```bash
+# Dry run - see what would be deleted
+uv run python -m tests.load.cleanup_loadtest_users --dry-run
+
+# Delete all loadtest users
+uv run python -m tests.load.cleanup_loadtest_users
+
+# Delete users with custom prefix
+uv run python -m tests.load.cleanup_loadtest_users --prefix mytest
+```
+
+### Disable Automatic Cleanup
+
+To keep test users after the benchmark for inspection:
+
+```bash
+uv run python -m tests.load.oauth_benchmark --users 2 --no-cleanup
+```
+
+## Troubleshooting
+
+### Leftover Test Users
+**Symptom**: Test users remain in Nextcloud after benchmark crashes
+
+**Solution**: Run the cleanup utility:
+```bash
+uv run python -m tests.load.cleanup_loadtest_users
+```
+
+### "User X not in pool" Error
+- Ensure user count doesn't exceed configured limits
+- Check that user creation succeeded in previous steps
+
+### CancelledError During Benchmark
+**Symptom**: Error message like `'CancelledError' object has no attribute 'username'` appears in logs
+
+**Cause**: Async task cancellation during benchmark shutdown or errors can cause race conditions in error handling
+
+**Solution**: This has been mitigated with defensive error handling. The worker now:
+- Catches `asyncio.CancelledError` specifically before general exceptions
+- Logs cancellation gracefully without attempting to access potentially invalid state
+- Re-raises the exception to allow proper cleanup chain
+
+If you still see this error, it's likely harmless and occurs during shutdown. The benchmark results should still be valid.
+
+### High Error Rates
+- Increase delay between operations (`await asyncio.sleep()` in worker)
+- Check OAuth token validity
+- Verify MCP OAuth server is running and accessible (port 8001)
+- Rebuild mcp-oauth container after code changes: `docker-compose up --build -d mcp-oauth`
+
+### Workflows Failing
+- Check step-by-step latencies to identify failing steps
+- Verify users have correct permissions
+- Review server logs for errors
+
+### MCP Session Creation Fails (401 Unauthorized)
+**Solution**: This issue has been fixed! OAuth tokens are now properly passed as Authorization headers when creating MCP sessions.
+
+If you still see 401 errors:
+- Rebuild the mcp-oauth container: `docker-compose up --build -d mcp-oauth`
+- Verify OAuth tokens are being acquired successfully in verbose mode
+- Check that the token hasn't expired (use shorter test durations during troubleshooting)
+
+## Future Enhancements
+
+- [x] Dynamic user creation (beyond 4 default users) - **COMPLETED**
+- [x] OAuth token injection for MCP sessions - **COMPLETED**
+- [x] Cancel scope error handling - **COMPLETED**
+- [x] Concurrent user creation and authentication - **COMPLETED** (3-4x speedup!)
+- [ ] Workflow templates for common patterns
+- [ ] Real-time dashboard for live monitoring
+- [ ] Historical comparison and regression detection
+- [ ] Load ramping (gradual user increase)
+- [ ] Geographic distribution simulation (latency injection)
+- [ ] Improve cleanup reliability in finally block
