+### 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)

+3. Response models inherit from `BaseResponse`, include `results` field + metadata

+- `SearchFilesResponse` in `nextcloud_mcp_server/models/webdav.py:113`

 #### 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` use Playwright automation
-- Uses Playwright headless browser automation to complete OAuth flow programmatically
+**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:812`
-- All Playwright fixtures: `playwright_oauth_token`, `nc_oauth_client`, `nc_mcp_oauth_client`, `nc_oauth_client_playwright`, `nc_mcp_oauth_client_playwright`
-- Multi-user fixtures: `alice_oauth_token`, `bob_oauth_token`, `charlie_oauth_token`, `diana_oauth_token`
-- Requires: `NEXTCLOUD_HOST`, `NEXTCLOUD_USERNAME`, `NEXTCLOUD_PASSWORD` environment variables
+  - Implementation: `shared_oauth_client_credentials` fixture in `tests/conftest.py`

+- **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/server/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/server/test_mcp_oauth.py --browser firefox --headed -v
+**Example Commands:**
+```bash

+uv run pytest tests/server/test_oauth*.py --browser firefox -v
 
-  # Run with Chromium (default)
-  uv run pytest tests/server/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)

+From: Chris Coutinho <chris@coutinho.io>
+Date: Mon, 13 Oct 2025 23:24:53 +0200
+Subject: [PATCH 1/2] feat: Advertise PKCE support in discovery document
+
+Add code_challenge_methods_supported to OpenID Connect discovery
+document when PKCE is enabled via proof_key_for_code_exchange config.
+
+Rationale:
+According to RFC 8414 Section 2, the code_challenge_methods_supported
+field in OAuth 2.0 Authorization Server Metadata has specific semantics:
+"If omitted, the authorization server does not support PKCE."
+
+This means that clients following RFC 8414 strictly will interpret the
+absence of this field as explicit non-support for PKCE, even if the
+authorization server technically supports it.
+
+Impact:
+- Standards-compliant OAuth clients (e.g., MCP clients) require explicit
+  advertisement of PKCE support before proceeding with authorization
+- The MCP (Model Context Protocol) specification mandates that clients
+  MUST refuse to proceed if code_challenge_methods_supported is absent
+- Other security-focused OAuth implementations may have similar checks
+
+Implementation:
+- Only advertises S256 (SHA-256) challenge method, which is the most
+  secure and widely supported method
+- Conditional on the existing proof_key_for_code_exchange app config
+- Maintains backward compatibility: only added when PKCE is enabled
+
+This change ensures the discovery document accurately reflects server
+capabilities per RFC 8414 semantics, enabling compatibility with
+strict standards-compliant OAuth clients.
+
+References:
+- RFC 8414: OAuth 2.0 Authorization Server Metadata
+- RFC 7636: Proof Key for Code Exchange by OAuth Public Clients
+- MCP Authorization Specification

+# Cookbook App
+
+### Cookbook Tools
+
+| Tool | Description |
+|------|-------------|
+| `nc_cookbook_import_recipe` | Import a recipe from a URL using schema.org metadata |
+| `nc_cookbook_create_recipe` | Create a new recipe with all schema.org fields |
+| `nc_cookbook_get_recipe` | Get a specific recipe by ID |
+| `nc_cookbook_update_recipe` | Update an existing recipe |
+| `nc_cookbook_delete_recipe` | Delete a recipe permanently |
+| `nc_cookbook_list_recipes` | Get all recipes in the database |
+| `nc_cookbook_search_recipes` | Search for recipes by keywords, tags, and categories |
+| `nc_cookbook_list_categories` | Get all known recipe categories |
+| `nc_cookbook_get_recipes_in_category` | Get all recipes in a specific category |
+| `nc_cookbook_list_keywords` | Get all known recipe keywords/tags |
+| `nc_cookbook_get_recipes_with_keywords` | Get all recipes that have specific keywords |
+| `nc_cookbook_set_config` | Set Cookbook app configuration |
+| `nc_cookbook_reindex` | Trigger a rescan of all recipes into the search database |
+
+### Cookbook Resources
+
+| Resource | Description |
+|----------|-------------|
+| `cookbook://version` | Get Cookbook app and API version information |
+| `cookbook://config` | Get Cookbook app configuration |
+| `nc://Cookbook/{recipe_id}` | Get a specific recipe by ID |
+
+## 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",

+
+### 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.

+| 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:

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

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

+# 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
+
+### 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
