+### 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
 
-- **Integration tests** in `tests/integration/` - Test real Nextcloud API interactions
+- **Integration tests** in `tests/client/` and `tests/server/` - Test real Nextcloud API interactions
 - **Fixtures** in `tests/conftest.py` - Shared test setup and utilities

-- **Important**: Integration tests run against live Docker containers. After making code changes to the MCP server, rebuild only the MCP container with `docker-compose up --build -d mcp` before running tests
+- **Important**: Integration tests run against live Docker containers. After making code changes:
+  - 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
 
 #### 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
+  - Stored in `.nextcloud_oauth_shared_test_client.json`
+  - Matches production MCP server behavior
+  - Each user gets their own unique access token
+  - Implementation: `shared_oauth_client_credentials` fixture in `tests/conftest.py`
+- **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
 - Uses `pytest-playwright-asyncio` for async Playwright fixtures
-- Playwright configuration: Use pytest CLI args like `--browser firefox --headed` to customize
-- Install browsers: `uv run playwright install firefox` (or `chromium`, `webkit`)
-- Example:
-  ```bash
-  # Run all OAuth tests with automated Playwright flow using Firefox
-  uv run pytest tests/integration/test_oauth*.py --browser firefox -v
+- **Playwright configuration**: Use pytest CLI args like `--browser firefox --headed` to customize
+- **Install browsers**: `uv run playwright install firefox` (or `chromium`, `webkit`)
 
-  # Run specific Playwright tests with visible browser for debugging
-  uv run pytest tests/integration/test_oauth_playwright.py --browser firefox --headed -v
+**Example Commands:**
+```bash
+# Run all OAuth tests with Playwright automation using Firefox
+uv run pytest tests/server/test_oauth*.py --browser firefox -v
 
-  # Run with Chromium (default)
-  uv run pytest tests/integration/test_oauth.py -v
-  ```
+# Run specific tests with visible browser for debugging
+uv run pytest tests/server/test_mcp_oauth.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
-- Example:
-  ```bash
-  # Run OAuth tests with interactive flow (will open browser and wait for manual login)
-  uv run pytest tests/integration/test_oauth_interactive.py -v
-  ```
+# Run with Chromium (default)
+uv run pytest tests/server/test_oauth*.py -v
+```
 
-**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`
+- OAuth client credentials cached in `.nextcloud_oauth_shared_test_client.json`
 
-**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.

+# 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

+- Claude Code calls `nc_notes_search_notes` tool
+- Returns results directly to user
+
+**Workflow 2: Assistant → Context Agent → Internal Tools**
+```
+User → Assistant → Context Agent → Send Email Tool
+```
+- User asks Assistant to send an email
+- Context Agent identifies "send_email" as dangerous
+- Requests user confirmation
+- Sends email via nc-py-api
+
+**Workflow 3: Assistant → Context Agent → External MCP**
+```
+User → Assistant → Context Agent → Nextcloud MCP Server → Notes
+```
+- User asks Assistant about notes
+- Context Agent consumes Nextcloud MCP Server as external MCP
+- Gets notes data via MCP protocol
+- Returns to user via Assistant

+## 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
+- **Strength**: Action-oriented, safe/dangerous tools, MCP aggregation
+- **Audience**: Nextcloud users via Assistant app, AI-driven workflows
+
+**Key Insight**: These are complementary, not competing. Context Agent could even consume Nextcloud MCP Server as one of its external MCP sources, creating a unified ecosystem where:
+- External clients access Nextcloud via Nextcloud MCP Server
+- Internal users leverage Context Agent for AI assistance
+- Context Agent aggregates both internal tools and external MCP servers (including Nextcloud MCP Server)

+## Recipe Management
+
+The server provides complete Nextcloud Cookbook integration, enabling you to manage your recipe collection:
+
+- **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`
+

+
+## 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** - `nc:read` and `nc: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 8959 endpoint for scope discovery
+- ✅ **Backward Compatible** - BasicAuth mode bypasses all scope checks
+
+### Supported Scopes
+
+| Scope | Description | Tool Count |
+|-------|-------------|------------|
+| `nc:read` | Read-only access to Nextcloud data | 36 tools |
+| `nc: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 nc:read nc: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 |
+|-------|------------|----------|
+| `nc:read` | Read-only access | Get notes, search files, list calendars, read contacts |
+| `nc: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 nc:read nc:write
+```
+
+**Read-Only:**
+```
+openid profile email nc:read
+```
+
+**No Custom Scopes (OIDC only):**
+```
+openid profile email
+```
+
+### Implementation
+
+All 90 MCP tools are decorated with scope requirements:
+
+```python
+@mcp.tool()
+@require_scopes("nc:read")
+async def nc_notes_get_note(note_id: int, ctx: Context):
+    """Get a note by ID (requires nc:read scope)"""
+    ...
+
+@mcp.tool()
+@require_scopes("nc:write")
+async def nc_notes_create_note(title: str, content: str, ctx: Context):
+    """Create a note (requires nc:write scope)"""
+    ...
+```
+
+**Coverage:**
+- ✅ 36 read tools decorated with `@require_scopes("nc:read")`
+- ✅ 54 write tools decorated with `@require_scopes("nc: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:
+
+**JWT with `nc:read` only:**
+- `list_tools()` returns 36 read-only tools
+- Write tools are hidden from the tool list
+
+**JWT with `nc:write` only:**
+- `list_tools()` returns 54 write-only tools
+- Read tools are hidden from the tool list
+
+**JWT with both scopes:**
+- `list_tools()` returns all 90 tools
+
+**JWT with no custom scopes:**
+- `list_tools()` returns 0 tools (all require `nc:read` or `nc:write`)
+
+**BasicAuth mode:**
+- `list_tools()` returns all 90 tools (no 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="nc:write",
+                  resource_metadata="http://server/.well-known/oauth-protected-resource"
+```
+
+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 8959's Protected Resource Metadata endpoint:
+
+**Endpoint:** `GET /.well-known/oauth-protected-resource`
+
+**Response:**
+```json
+{
+  "resource": "http://localhost:8002",
+  "scopes_supported": ["nc:read", "nc: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 three MCP server variants:
+
+| Service | Port | Auth Type | Token Type | Use Case |
+|---------|------|-----------|------------|----------|
+| `mcp` | 8000 | BasicAuth | N/A | Development, testing |
+| `mcp-oauth` | 8001 | OAuth | Opaque | Standard OAuth flows |
+| `mcp-oauth-jwt` | 8002 | OAuth | JWT | Production, JWT testing |
+
+### JWT Service Configuration
+
+The `mcp-oauth-jwt` service uses **Dynamic Client Registration (DCR)** by default:
+
+**Default Configuration (DCR):**
+```yaml
+mcp-oauth-jwt:
+  build: .
+  command: ["--transport", "streamable-http", "--oauth", "--port", "8002"]
+  ports:
+    - 127.0.0.1:8002:8002
+  environment:
+    - NEXTCLOUD_HOST=http://app:80
+    - NEXTCLOUD_MCP_SERVER_URL=http://localhost:8002
+    - NEXTCLOUD_PUBLIC_ISSUER_URL=http://localhost:8080
+    - NEXTCLOUD_OIDC_SCOPES=openid profile email nc:read nc:write
+    - NEXTCLOUD_OIDC_TOKEN_TYPE=jwt
+  volumes:
+    - ./oauth-storage:/app/.oauth  # Optional: persist DCR credentials
+```
+
+**With Pre-Configured Credentials:**
+```yaml
+mcp-oauth-jwt:
+  build: .
+  command: ["--transport", "streamable-http", "--oauth", "--port", "8002"]
+  ports:
+    - 127.0.0.1:8002:8002
+  environment:
+    - NEXTCLOUD_HOST=http://app:80
+    - NEXTCLOUD_MCP_SERVER_URL=http://localhost:8002
+    - 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
+    - NEXTCLOUD_OIDC_TOKEN_TYPE=jwt
+```
+
+**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** - Set `TOKEN_TYPE=jwt` for better performance
+- **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 nc:read nc: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 nc:read nc: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 nc:read nc: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 nc:read nc: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:433-488`)
+- Overrides FastMCP's `list_tools()` method
+- Filters based on user's JWT token scopes
+- 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`
+- Advertises `["nc:read", "nc:write"]`
+- RFC 8959 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` |

+
+## 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 `nc:read` or `nc: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 `nc: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 `nc: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 `nc:read` and `nc: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 `nc:read` only
+- `write_only_oauth_client_credentials` - Client with `nc: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 `nc:read`
+- `playwright_oauth_token_write_only` - Obtains token with `nc: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 nc:read nc:write" \
+  "Client Name" \
+  "http://callback/url"
+```
+
+### Issue: All Tools Visible Despite Read-Only Token
+
+**Symptom:** User with `nc: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-jwt | grep "OAuth mode"
+
+# Should see: "Running in OAuth mode"
+
+# If not, check environment variables:
+docker compose exec mcp-oauth-jwt 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 nc:read nc: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-jwt | grep "WWW-Authenticate scope challenges enabled"
+
+# Should see this during startup
+
+# Check exception handling
+docker compose logs mcp-oauth-jwt | 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-jwt | grep -E "JWT|scope|tool"
+
+# Check for issuer mismatches
+docker compose logs mcp-oauth-jwt | 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-jwt:
+  image: ghcr.io/yourusername/nextcloud-mcp-server:latest
+  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 nc:read nc:write
+    - NEXTCLOUD_OIDC_TOKEN_TYPE=jwt
+  ports:
+    - "8002:8002"
+```
+
+### 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', 'nc:read', 'nc:write'}
+
+# Failures
+WARNING JWT issuer validation failed: Invalid issuer
+WARNING Missing required scopes: nc:write
+```
+
+### Known Limitations
+
+1. **No Fine-Grained Scopes** - Only coarse `nc:read` and `nc: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

-### 2. PKCE Support Advertisement in Discovery
+### 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
 
-**Upstream PR**: [H2CK/oidc#584](https://github.com/H2CK/oidc/pull/584) - Submitted 2025-10-13
-- **Changes**: Adds `code_challenge_methods_supported: ["S256"]` to discovery document when PKCE is enabled
-- **Size**: +5 lines added, 0 deleted
-- **Status**: Open, awaiting review
+**Why It Mattered**:
+- MCP specification requires PKCE with S256 code challenge method
+- RFC 7636 PKCE provides security for public clients (no client secret)

+# 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]:

+                await session.initialize()
+                session_holder["session"] = session
+
+                # Keep session alive until cancelled
+                try:
+                    await anyio.sleep_forever()
+                except anyio.get_cancelled_exc_class():

+
+        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.

+## Decision Matrix
+
+| Solution | Code Clarity | Maintenance | Performance | Safety | Effort |
+|----------|--------------|-------------|-------------|--------|--------|
+| **Solution 1** (Implemented) | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
+| Solution 2 (Task-Isolated) | ⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐ |
+| Solution 3 (Function-Scoped) | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
+| 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
+
+## Testing Results
+
+All tests pass cleanly with the implementation:
+
+```bash
+$ uv run pytest tests/server/test_mcp.py -v

+
+## 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
+
+## Related Resources

+
+## 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-jwt container will trigger the OAuth flow
+docker compose logs -f mcp-oauth-jwt
+```
+
+**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:8002/oauth/callback&scope=openid+profile+email+nc:read+nc: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)
+     - ✓ nc:read (custom scope, shown as-is)
+     - ✓ nc: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

-    Validates access tokens using Nextcloud OIDC userinfo endpoint.

-    1. Calls the userinfo endpoint with the bearer token
-    2. Caches successful responses to avoid repeated API calls
-    3. Extracts username from the 'sub' or 'preferred_username' claim
-    4. Optionally supports JWT validation for performance (future enhancement)

+    2. For opaque tokens: Falls back to userinfo endpoint validation
+    3. Caches successful responses to avoid repeated API calls/verifications

-    or returns HTTP 400/401 if the token is invalid or expired.
+    JWT validation provides:
+    - Faster validation (no HTTP call needed)
+    - Direct scope extraction from token payload
+    - Signature verification using JWKS

+# 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
+
+```
+tests/load/
+├── oauth_pool.py          # OAuth user pool management
+├── oauth_workloads.py     # Multi-user workflow definitions
+├── oauth_metrics.py       # Enhanced metrics collection
+├── 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
