+#### Writing Mocked Unit Tests
+
+For client-layer tests that verify response parsing logic, use mocked HTTP responses instead of real network calls:
+
+**Pattern:**
+```python
+import httpx
+import pytest
+from nextcloud_mcp_server.client.notes import NotesClient
+from tests.conftest import create_mock_note_response
+
+async def test_notes_api_get_note(mocker):
+    """Test that get_note correctly parses the API response."""
+    # Create mock response using helper functions
+    mock_response = create_mock_note_response(
+        note_id=123,
+        title="Test Note",
+        content="Test content",
+        category="Test",
+        etag="abc123",
+    )
+
+    # Mock the _make_request method
+    mock_client = mocker.AsyncMock(spec=httpx.AsyncClient)
+    mock_make_request = mocker.patch.object(
+        NotesClient, "_make_request", return_value=mock_response
+    )
+
+    # Create client and test
+    client = NotesClient(mock_client, "testuser")
+    note = await client.get_note(note_id=123)
+
+    # Verify the response was parsed correctly
+    assert note["id"] == 123
+    assert note["title"] == "Test Note"
+    # Verify the correct API endpoint was called
+    mock_make_request.assert_called_once_with("GET", "/apps/notes/api/v1/notes/123")
+```
+
+**Mock Response Helpers in `tests/conftest.py`:**
+- `create_mock_response()` - Generic HTTP response builder
+- `create_mock_note_response()` - Pre-configured note response
+- `create_mock_error_response()` - Error responses (404, 412, etc.)
+
+**Benefits:**
+- ⚡ Fast execution (~0.1s vs minutes for integration tests)
+- 🔒 No Docker dependency
+- 🎯 Tests focus on response parsing logic
+- ♻️ Repeatable and deterministic
+
+**When to use:**
+- Testing client methods that parse JSON responses
+- Testing error handling (404, 412, etc.)
+- Testing request parameter building
+
+**When NOT to use (keep as integration tests):**
+- Complex protocol interactions (CalDAV, CardDAV, WebDAV)
+- Multi-component workflows (Notes + WebDAV attachments)
+- OAuth flows
+- End-to-end MCP tool testing
+
+**Reference Implementation:**
+- See `tests/client/notes/test_notes_api.py` for complete examples
+- Mark unit tests with `pytestmark = pytest.mark.unit`
+- Run with: `uv run pytest tests/unit/ tests/client/notes/test_notes_api.py -v`
+
 #### OAuth/OIDC Testing
 OAuth integration tests use **automated Playwright browser automation** to complete the 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
+  - **Created fresh for each test session** via Dynamic Client Registration (DCR)
+  - Matches production MCP server behavior (one client, multiple user tokens)
   - Each user gets their own unique access token
+  - **Automatic cleanup**: Client is registered at session start, deleted at session end (RFC 7592)
   - Implementation: `shared_oauth_client_credentials` fixture in `tests/conftest.py`
+  - **Note**: Client deletion may fail due to Nextcloud middleware (logged as warning). This doesn't affect tests.
 - **Available fixtures**: `playwright_oauth_token`, `nc_oauth_client`, `nc_mcp_oauth_client`
 - **Multi-user fixtures**: `alice_oauth_token`, `bob_oauth_token`, `charlie_oauth_token`, `diana_oauth_token`
 - **Requirements**: `NEXTCLOUD_HOST`, `NEXTCLOUD_USERNAME`, `NEXTCLOUD_PASSWORD` environment variables

 > - **Impact**: Without the patch, most app-specific APIs (Notes, Calendar, Contacts, Deck, etc.) will fail with 401 errors
-> - **Production use**: Wait for upstream patches to be merged into official releases
+> - **What works without patches**: OAuth flow, PKCE support (with `oidc` v1.10.0+), OCS APIs
+> - **Production use**: Wait for upstream patch to be merged into official releases

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

+# JWT OAuth Reference - Nextcloud MCP Server
+

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

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

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

+
+## Troubleshooting
+
+### Issue: JWT Issuer Validation Failed
+
+**Symptom:**
+```
+WARNING JWT issuer validation failed: Invalid issuer
+WARNING JWT verification failed, will try other methods
+✅ Extracted scopes from access token: {'openid', 'profile'}
+```
+
+**Cause:** Token's `iss` claim doesn't match expected issuer URL. This often happens when:
+- Using `localhost` vs `127.0.0.1` inconsistently
+- MCP server uses internal URL but clients use public URL
+
+**Solution:**
+```bash
+# Option 1: Use consistent URLs
+export NEXTCLOUD_PUBLIC_ISSUER_URL=http://localhost:8080
+# Ensure all test fixtures also use localhost:8080
+
+# Option 2: Check discovery document
+curl http://localhost:8080/.well-known/openid-configuration | jq .issuer
+# Use this exact issuer in NEXTCLOUD_PUBLIC_ISSUER_URL
+```
+
+**Impact if not fixed:**
+- JWT validation falls back to userinfo endpoint
+- Scopes inferred from userinfo (only standard OIDC scopes, no custom scopes)
+- Result: 0 tools visible or incorrect tool filtering
+
+### Issue: Scopes Not Present in JWT
+
+**Symptom:** JWT token doesn't contain `scope` claim or contains empty string
+
+**Cause:** Client's `allowed_scopes` is empty or not configured
+
+**Solution:**
+```bash
+# Check client configuration
+docker compose exec app php occ oidc:list
+
+# Look for allowed_scopes in output
+# If empty, recreate client with --allowed_scopes
+docker compose exec app php occ oidc:create \
+  --token_type=jwt \
+  --allowed_scopes="openid profile email mcp:notes:read mcp:notes:write" \
+  "Client Name" \
+  "http://callback/url"
+```
+
+### Issue: All Tools Visible Despite Read-Only Token
+
+**Symptom:** User with `mcp:notes:read` token can see all 90 tools including write tools
+
+**Cause:** Server running in BasicAuth mode, not OAuth mode
+
+**Solution:**
+```bash
+# Verify OAuth mode is active
+docker compose logs mcp-oauth | grep "OAuth mode"
+
+# Should see: "Running in OAuth mode"
+
+# If not, check environment variables:
+docker compose exec mcp-oauth env | grep NEXTCLOUD_OIDC
+
+# Ensure no NEXTCLOUD_USERNAME or NEXTCLOUD_PASSWORD set
+```
+
+### Verifying DCR Scope Configuration
+
+DCR **now properly sets `allowed_scopes`** when the `scope` parameter is provided during registration.
+
+**To verify DCR scopes are working:**
+
+```bash
+# Check the registered client's allowed_scopes via database
+docker compose exec db mariadb -u nextcloud -ppassword nextcloud \
+  -e "SELECT name, allowed_scopes FROM oc_oauth2_clients WHERE name LIKE 'DCR-%' ORDER BY id DESC LIMIT 1;"
+
+# Should show your requested scopes (e.g., "openid profile email mcp:notes:read mcp:notes:write")
+```
+
+**If scopes are missing:**
+1. Ensure `NEXTCLOUD_OIDC_SCOPES` environment variable is set correctly
+2. Check MCP server startup logs for the scopes being requested
+3. Verify DCR is enabled in Nextcloud OIDC app settings
+4. Delete `.nextcloud_oauth_client.json` and restart to force re-registration
+
+### Issue: Token Type Case Sensitivity
+
+**Symptom:** JWT tokens not generated even though `token_type=JWT` set
+
+**Cause:** OIDC app checks `token_type === 'jwt'` (lowercase)
+
+**Solution:** Always use lowercase:
+```bash
+# Correct
+export NEXTCLOUD_OIDC_TOKEN_TYPE=jwt
+
+# Incorrect (will generate opaque tokens)
+export NEXTCLOUD_OIDC_TOKEN_TYPE=JWT
+```
+
+### Issue: Missing WWW-Authenticate Header
+
+**Symptom:** 403 error doesn't include `WWW-Authenticate` header
+
+**Cause:** Server not in OAuth mode, or exception not being caught
+
+**Solution:**
+```bash
+# Check server logs for OAuth mode
+docker compose logs mcp-oauth | grep "WWW-Authenticate scope challenges enabled"
+
+# Should see this during startup
+
+# Check exception handling
+docker compose logs mcp-oauth | grep "InsufficientScopeError"
+```
+
+### Debugging Tools
+
+**Check JWT contents:**
+```bash
+# Decode JWT (base64 decode the payload)
+echo "JWT_PAYLOAD_PART" | base64 -d | jq .
+```
+
+**Check database scopes:**
+```bash
+# View access tokens with scopes
+docker compose exec db mariadb -u nextcloud -ppassword nextcloud \
+  -e "SELECT id, client_id, user_id, scope FROM oc_oidc_access_tokens ORDER BY id DESC LIMIT 5;"
+
+# View user consents
+docker compose exec db mariadb -u nextcloud -ppassword nextcloud \
+  -e "SELECT user_id, client_id, scopes_granted FROM oc_oidc_user_consents;"
+```
+
+**Check server logs:**
+```bash
+# Follow JWT verification logs
+docker compose logs -f mcp-oauth | grep -E "JWT|scope|tool"
+
+# Check for issuer mismatches
+docker compose logs mcp-oauth | grep -i issuer
+```
+
+---
+
+## Production Deployment
+
+### Deployment Checklist
+
+✅ **Use JWT Tokens** - Enable `token_type=jwt` for better performance
+✅ **Configure Allowed Scopes** - Always set `allowed_scopes` on OAuth clients
+✅ **Use Pre-Configured Clients** - Avoid DCR limitation with manual client creation
+✅ **Consistent URLs** - Use same URL for `NEXTCLOUD_HOST` and `PUBLIC_ISSUER_URL`
+✅ **Secure Credentials** - Store client credentials securely (environment variables or secrets management)
+✅ **Monitor Token Size** - JWT tokens are 10-15x larger than opaque (not usually an issue)
+✅ **Enable Logging** - Configure appropriate log levels for JWT verification
+
+### Production Configuration Example

+  ports:

+```
+
+### Security Considerations
+
+**Token Storage:**
+- Never commit credentials to version control
+- Use environment variables or secrets management
+- Rotate client secrets periodically
+
+**Scope Configuration:**
+- Grant minimum necessary scopes to clients
+- Use read-only tokens for AI assistants that don't need write access
+- Review OAuth client list regularly
+
+**Network Security:**
+- Use HTTPS in production
+- Ensure issuer URL matches public URL
+- Configure proper CORS headers
+
+### Monitoring
+
+**Key Metrics:**
+- JWT verification success/failure rate
+- Scope challenge frequency (indicates clients with insufficient scopes)
+- Token validation latency
+- Tool execution by scope (identify unused scopes)
+
+**Log Patterns:**
+```bash
+# Success
+INFO JWT verified successfully for user: admin
+INFO ✅ Extracted scopes from access token: {'openid', 'profile', 'email', 'mcp:notes:read', 'mcp:notes:write'}
+
+# Failures
+WARNING JWT issuer validation failed: Invalid issuer
+WARNING Missing required scopes: mcp:notes:write
+```
+
+### Known Limitations
+
+1. **No Fine-Grained Scopes** - Only coarse `mcp:notes:read` and `mcp:notes:write` (not per-app scopes)
+2. **No Refresh Token Support** - Tokens must be reacquired when expired
+
+### Future Enhancements
+
+**Potential Improvements:**
+- Per-app scopes (`nc:notes:read`, `nc:calendar:write`)
+- Resource-level filtering (apply to MCP resources, not just tools)
+- Automatic scope discovery from decorated tools
+- Admin UI for scope management

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

-### 2. PKCE Support 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)
+- RFC 8414 states that absence of `code_challenge_methods_supported` means PKCE is **not supported**
+- Prevents authorization code interception attacks
+
+**Upstream PR**: [H2CK/oidc#584](https://github.com/H2CK/oidc/pull/584) - ✅ **Merged 2025-10-20**

+# Testing OIDC Consent Feature
+
+This guide explains how to test the OIDC consent feature using the development version of the OIDC app mounted into the Docker environment.
+
+## Setup
+
+### Volume Mount Configuration
+
+The development OIDC app is mounted from `~/Software/oidc` into the container at `/opt/apps/oidc`:
+
+```yaml
+# docker-compose.yml
+volumes:
+  - ../Software/oidc:/opt/apps/oidc:ro
+```
+
+**Why mount outside `/var/www/html/`?**
+- The Nextcloud container uses `rsync` to initialize `/var/www/html/` from the image
+- Mounting inside that path causes conflicts (rsync tries to delete mounted directories)
+- Mounting to `/opt/apps/oidc` avoids rsync entirely
+- Nextcloud supports multiple app directories via the `apps_paths` configuration
+
+**How multiple app paths work:**
+- Nextcloud can load apps from multiple directories
+- The post-installation hook registers `/opt/apps` as an additional app directory (index 2)
+- Apps in default paths (index 0 and 1) are still available
+- All directories are scanned for apps, but `/opt/apps` is read-only
+
+This setup allows you to:
+- Test changes without rebuilding containers
+- Avoid needing npm/node in the container (JS already built on host)
+- Iterate quickly on development
+- Install other Nextcloud apps normally (custom_apps remains writable)
+
+### How It Works
+
+1. **Mount Development App**: Docker mounts `~/Software/oidc` to `/opt/apps/oidc` (outside Nextcloud's path)
+2. **Register App Path**: The `10-install-oidc-app.sh` hook configures `/opt/apps` as an additional app directory
+3. **Enable App**: The hook enables the OIDC app from `/opt/apps/oidc`
+4. **Run Migrations**: Nextcloud detects pending migrations and runs them automatically
+5. **Configure OIDC**: Dynamic client registration and PKCE are enabled
+
+## Starting the Stack
+
+```bash
+cd ~/Projects/nextcloud-mcp-server
+
+# Start fresh (recommended for first test)
+docker compose down -v
+docker compose up -d
+
+# Wait for initialization (check logs)
+docker compose logs -f app
+```
+
+The post-installation hooks will:
+1. Configure custom_apps path (already done)
+2. Enable OIDC app from mounted directory
+3. Run database migrations (including consent table creation)
+4. Configure OIDC settings
+
+## Verifying Installation
+
+### Before Container Restart
+
+Before running `docker compose up -d`, the consent feature will NOT be active:
+- ❌ No `oc_oidc_user_consents` table in database
+- ❌ Migration 0015 not applied yet
+- ❌ ConsentController class not loaded
+- ❌ Consent routes not registered
+
+You can verify this with:
+```bash
+# Check migrations applied (should stop at 0014)
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT version FROM oc_migrations WHERE app = 'oidc' ORDER BY version DESC LIMIT 3;" nextcloud
+
+# Check for consent table (should return empty)
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SHOW TABLES LIKE 'oc_oidc_user_consents';" nextcloud
+```
+
+### After Container Restart
+
+After `docker compose up -d` with the mounted OIDC directory, the consent feature should be active:
+- ✅ `oc_oidc_user_consents` table exists
+- ✅ Migration 0015 (Version0015Date20251123100100) applied
+- ✅ ConsentController routes registered
+- ✅ Consent screen appears during OAuth flows
+
+### Check App Status
+
+```bash
+docker compose exec app php occ app:list | grep -A 2 oidc
+```
+
+Expected output:
+```
+  - oidc: 1.10.0 (enabled)
+```
+
+### Verify App Paths Configuration
+
+Verify that `/opt/apps` is registered as an additional app directory:
+
+```bash
+# Check configured app paths
+docker compose exec app php occ config:system:get apps_paths
+
+# Verify the mount is accessible
+docker compose exec app ls -la /opt/apps/oidc/
+
+# Verify custom_apps is writable (for normal app installation)
+docker compose exec -u www-data app touch /var/www/html/custom_apps/.test && echo "✅ custom_apps is writable" || echo "❌ custom_apps NOT writable"
+docker compose exec app rm -f /var/www/html/custom_apps/.test
+```
+
+Expected: Output should show multiple app paths including index 2 (/opt/apps).
+
+### Verify Consent Files
+
+```bash
+# Check controller exists in mounted location
+docker compose exec app ls -la /opt/apps/oidc/lib/Controller/ConsentController.php
+
+# Check Vue component exists
+docker compose exec app ls -la /opt/apps/oidc/src/Consent.vue
+
+# Check built JS exists
+docker compose exec app ls -lh /opt/apps/oidc/js/oidc-consent.js
+```
+
+### Verify Database Migration
+
+**Note**: These checks will only pass after restarting containers with the mounted OIDC app.
+
+```bash
+# Check if consent table exists
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SHOW TABLES LIKE 'oc_oidc_user_consents';"
+
+# Check table structure
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "DESCRIBE oc_oidc_user_consents;"
+
+# Verify migration 0015 was applied
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT app, version FROM oc_migrations WHERE app = 'oidc' AND version LIKE '%0015%';"
+```
+
+Expected table structure:
+- id: int(10) unsigned, auto_increment, primary key
+- user_id: varchar(256), not null
+- client_id: int(10) unsigned, not null
+- scopes_granted: varchar(512), not null
+- created_at: int(10) unsigned, not null
+- updated_at: int(10) unsigned, not null
+- expires_at: int(10) unsigned, nullable
+
+### Verify Routes
+
+```bash
+docker compose exec app php occ router:list | grep consent
+```
+
+Expected output:
+```
+oidc.Consent.show        GET    apps/oidc/consent
+oidc.Consent.grant       POST   apps/oidc/consent/grant
+oidc.Consent.deny        POST   apps/oidc/consent/deny
+```
+
+## Testing the Consent Flow
+
+### 1. Create an OAuth Client
+
+The JWT client is automatically created by the post-installation hooks:
+
+```bash
+# Check if JWT client exists
+docker compose exec app cat /var/www/html/.oauth-jwt/nextcloud_oauth_client.json
+```
+
+### 2. Initiate Authorization Flow
+
+You can test using the MCP OAuth container or manually:
+
+**Option A: Using MCP OAuth container**
+```bash
+# The mcp-oauth container will trigger the OAuth flow
+docker compose logs -f mcp-oauth
+```
+
+**Option B: Manual browser test**
+1. Get client_id from the JWT client JSON
+2. Visit in browser:
+```
+http://localhost:8080/apps/oidc/authorize?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=http://localhost:8001/oauth/callback&scope=openid+profile+email+mcp:notes:read+mcp:notes:write&state=test123
+```
+
+### 3. Expected Behavior
+
+**First Authorization:**
+1. User logs in (if not already authenticated)
+2. **Consent screen appears** with:
+   - Application name: "Nextcloud MCP Server JWT"
+   - List of requested scopes with descriptions:
+     - ✓ Basic authentication (openid) - required, cannot deselect
+     - ✓ Profile information (profile)
+     - ✓ Email address (email)
+     - ✓ mcp:notes:read (custom scope, shown as-is)
+     - ✓ mcp:notes:write (custom scope, shown as-is)
+   - "Allow" and "Deny" buttons
+3. User selects scopes and clicks "Allow"
+4. Authorization proceeds with selected scopes
+5. Consent is stored in database
+
+**Subsequent Authorizations:**
+- Same scopes → No consent screen (uses stored consent)
+- Different scopes → Consent screen appears again
+- If user clicks "Deny" → Returns `error=access_denied` to client
+
+### 4. Verify Consent Stored
+
+After granting consent:
+
+```bash
+# View all stored consents with formatted timestamps
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "
+SELECT
+    user_id,
+    client_id,
+    scopes_granted,
+    FROM_UNIXTIME(created_at) as created,
+    FROM_UNIXTIME(updated_at) as updated,
+    FROM_UNIXTIME(expires_at) as expires
+FROM oc_oidc_user_consents;
+" nextcloud
+
+# Or for a compact view:
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT * FROM oc_oidc_user_consents;" nextcloud
+```
+
+## Troubleshooting
+
+### Consent Screen Not Appearing

+**Check browser console** (F12 → Console tab):
+```
+# Look for JS errors like:
+Failed to load resource: js/oidc-consent.js
+```
+
+**Check Nextcloud logs:**
+```bash
+docker compose exec app tail -f /var/www/html/data/nextcloud.log | grep -i consent
+```
+
+**Verify JS file loaded:**
+```bash
+# Check file exists and has correct size (~73KB)
+docker compose exec app ls -lh /opt/apps/oidc/js/oidc-consent.js
+```
+
+**Clear Nextcloud caches:**
+```bash
+docker compose exec app php occ maintenance:repair
+docker compose restart app
+```
+
+### Migration Didn't Run
+
+**Check which migrations have been applied:**
+```bash
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT app, version FROM oc_migrations WHERE app = 'oidc' ORDER BY version;" nextcloud
+```
+
+Expected to see `Version0015Date20251123100100` in the list.
+
+**Manually trigger migrations:**
+```bash
+# Disable and re-enable app (triggers all pending migrations)
+docker compose exec app php occ app:disable oidc
+docker compose exec app php occ app:enable oidc
+
+# Verify migration 0015 was applied
+docker compose exec -T db mariadb -u nextcloud -ppassword nextcloud -e "SELECT version FROM oc_migrations WHERE app = 'oidc' AND version LIKE '%0015%';" nextcloud
+```
+
+### Routes Not Registered
+
+If `router:list` doesn't show consent routes:
+
+```bash
+# The autoloader might not have picked up new classes
+# Restart the container
+docker compose restart app
+
+# Wait for it to be ready
+sleep 10
+
+# Try again
+docker compose exec app php occ router:list | grep consent
+```
+
+If still not working, check if ConsentController is accessible:
+```bash
+docker compose exec app php -r "
+require_once '/var/www/html/lib/base.php';
+\$class = 'OCA\\OIDCIdentityProvider\\Controller\\ConsentController';
+if (class_exists(\$class)) {
+    echo \"Class exists\n\";
+} else {
+    echo \"Class not found\n\";
+}
+"
+```
+
+## Making Changes
+
+### Frontend Changes (Vue.js)
+
+1. Edit source file on host:
+```bash
+cd ~/Software/oidc
+# Edit src/Consent.vue
+```
+
+2. Rebuild JS:
+```bash
+npm run build
+```
+
+3. Refresh browser (container sees changes immediately via volume mount at /opt/apps/oidc)
+
+### Backend Changes (PHP)
+
+1. Edit files on host:
+```bash
+cd ~/Software/oidc
+# Edit lib/Controller/ConsentController.php or other PHP files
+```
+
+2. Changes are immediately visible (PHP is interpreted, no build step)
+
+3. For new classes or major changes, restart container:
+```bash
+docker compose restart app
+```
+
+### Database Schema Changes
+
+If you modify the migration:
+
+```bash
+# Changes won't be picked up if migration already ran
+# Need to recreate the database:
+docker compose down -v  # Removes volumes
+docker compose up -d    # Fresh start with clean DB
+```
+
+## Cleanup
+
+### Reset Everything
+
+```bash
+cd ~/Projects/nextcloud-mcp-server
+docker compose down -v
+```
+
+This removes:
+- All containers
+- Database volume (all data)
+- OAuth client credentials
+
+### Keep Data, Restart App
+
+```bash
+docker compose restart app
+```
+
+This preserves:
+- Database (consents, clients, users)
+- OAuth client credentials
+
+## Development Workflow Summary
+
+1. **Make changes** in `~/Software/oidc`
+2. **Build JS** if you changed Vue files: `npm run build`
+3. **Test immediately** - refresh browser or restart container
+4. **No need** to rebuild Docker images or reinstall app
+5. **Iterate quickly** with instant feedback
+
+## Production Deployment
+
+When ready to deploy:
+
+1. **Create patch file** (already done):
+   ```bash
+   cd ~/Software/oidc
+   git format-patch master --stdout > user-consent-feature.patch
+   ```
+
+2. **Test patch** in clean environment:
+   ```bash
+   # In a production-like environment
+   cd /path/to/production/oidc
+   git apply user-consent-feature.patch
+   npm install
+   npm run build
+   php occ app:disable oidc
+   php occ app:enable oidc
+   ```
+
+3. **Verify migration** runs automatically on app enable
+
+4. **Submit pull request** to upstream repository
