+### 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.

+- **Integration tests** in `tests/client/` and `tests/server/` - Test real Nextcloud API interactions

-- **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.
 
+> [!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 endpoint for external LLMs. 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. See our [detailed comparison](docs/comparison-context-agent.md) to understand which approach fits your use case.

+# 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
+
+### Context Agent
+
+```python
+# Dynamic loading at runtime
+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
+- `@safe_tool` / `@dangerous_tool` decorators
+- Dynamic tool regeneration with fresh context
+- Tools returned as list from async function
+- Availability checking per module

+
+**Safe Tools** (read-only):
+- `list_calendars`
+- `find_person_in_contacts`
+- `list_talk_conversations`
+- `get_file_content`
+- `get_folder_tree`
+
+**Dangerous Tools** (write operations):

+- `create_public_sharing_link`
+- `send_email`
+
+### 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

+- User asks Claude Code to search notes
+- 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

+
+## 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`
+
+**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

+# 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://127.0.0.1:8000/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://127.0.0.1:8000/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://127.0.0.1:8000/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://127.0.0.1:8000/mcp") as (read1, write1, _):
+        async with ClientSession(read1, write1) as session1:
+            await session1.initialize()
+
+            async with streamablehttp_client("http://127.0.0.1:8001/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://127.0.0.1:8000/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
+============================================= test session starts ==============================================

+
+## 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.

+# 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://127.0.0.1:8001/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
+

+
+    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,

+
+## 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
