feat: Implement ADR-004 Hybrid Flow with comprehensive integration tests
Implement the ADR-004 Hybrid Flow OAuth pattern where the MCP server intercepts the OAuth callback to obtain master refresh tokens while maintaining PKCE security for clients. ## Implementation ### OAuth Routes (ADR-004 Hybrid Flow) - Add `/oauth/authorize` endpoint: Intercepts client OAuth initiation - Add `/oauth/callback` endpoint: Receives IdP callback, stores master token - Add `/oauth/token` endpoint: Exchanges MCP code for client access token - Implement PKCE code challenge/verifier validation - Store OAuth sessions with state/challenge correlation ### MCP Server Integration - Update `setup_oauth_config()` to return client_id and client_secret - Initialize OAuth context in Starlette lifespan for login routes - Add OAuth session storage to RefreshTokenStorage - Configure authlib dependency for OAuth flow management ### Integration Tests - Create `test_adr004_hybrid_flow.py` with Playwright automation - Add `adr004_hybrid_flow_mcp_client` session-scoped fixture - Test MCP session establishment with hybrid flow token - Test tool execution using stored refresh tokens (on-behalf-of pattern) - Test persistent access across multiple operations - All tests passing: ✅ 3 passed in 8.82s ### Documentation - Update ADR-004 with comprehensive Testing section - Add integration test commands and coverage details - Document test implementation and verification steps - Create TESTING_INSTRUCTIONS.md for manual and automated testing - Include manual test scripts for reference/debugging ## What This Enables ✅ PKCE code challenge/verifier flow ✅ MCP server intercepts OAuth callback and stores master refresh token ✅ Client receives MCP access token (not master token) ✅ MCP session establishment with hybrid flow token ✅ Tool execution using stored refresh tokens (on-behalf-of pattern) ✅ Multiple operations without re-authentication ✅ Proper token isolation (client never sees master token) ## Testing Run ADR-004 integration tests: ```bash uv run pytest tests/server/oauth/test_adr004_hybrid_flow.py --browser firefox -v ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Manual OAuth Flow Testing
|
||||
|
||||
This directory contains manual test scripts for OAuth flows that require browser interaction.
|
||||
|
||||
## ADR-004 OAuth Hybrid Flow Test
|
||||
|
||||
The `test_adr004_oauth_flow.py` script tests the complete OAuth flow described in ADR-004.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
1. **Install Playwright browsers:**
|
||||
```bash
|
||||
uv run playwright install firefox
|
||||
```
|
||||
|
||||
2. **Start MCP server with OAuth enabled:**
|
||||
|
||||
For Nextcloud OIDC:
|
||||
```bash
|
||||
export ENABLE_OFFLINE_ACCESS=true
|
||||
export TOKEN_ENCRYPTION_KEY=$(uv run python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())")
|
||||
docker-compose up --build -d mcp-oauth
|
||||
```
|
||||
|
||||
For Keycloak:
|
||||
```bash
|
||||
export ENABLE_OFFLINE_ACCESS=true
|
||||
export TOKEN_ENCRYPTION_KEY=$(uv run python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())")
|
||||
docker-compose up --build -d mcp-keycloak
|
||||
```
|
||||
|
||||
### Running the Test
|
||||
|
||||
**Test with Nextcloud OIDC:**
|
||||
```bash
|
||||
uv run python tests/manual/test_adr004_oauth_flow.py --provider nextcloud
|
||||
```
|
||||
|
||||
**Test with Keycloak:**
|
||||
```bash
|
||||
uv run python tests/manual/test_adr004_oauth_flow.py --provider keycloak
|
||||
```
|
||||
|
||||
**Headless mode:**
|
||||
```bash
|
||||
uv run python tests/manual/test_adr004_oauth_flow.py --provider nextcloud --headless
|

# ADR-004 OAuth Flow Testing Instructions
|
||||
|
||||
## Automated Integration Test (Recommended)
|
||||
|
||||
The ADR-004 Hybrid Flow is now fully tested via automated integration tests using Playwright:
|
||||
|
||||
```bash
|
||||
# Run all ADR-004 tests
|
||||
uv run pytest tests/server/oauth/test_adr004_hybrid_flow.py --browser firefox -v
|
||||
|
||||
# Run specific test
|
||||
uv run pytest tests/server/oauth/test_adr004_hybrid_flow.py::test_adr004_hybrid_flow_tool_execution --browser firefox -v
|
||||
```
|
||||
|
||||
These tests verify:
|
||||
- ✅ PKCE code challenge/verifier flow
|
||||
- ✅ MCP server intercepts OAuth callback
|
||||
- ✅ Master refresh token storage
|
||||
- ✅ Client receives MCP access token
|
||||
- ✅ MCP session establishment with hybrid flow token
|
||||
- ✅ Tool execution using stored refresh tokens
|
||||
- ✅ Multiple operations without re-authentication
|
||||
|
||||
## Manual Test (Legacy)
|
||||
|
||||
For manual testing or debugging, you can use the standalone test script:
|
||||
|
||||
```bash
|
||||
# Make sure port 8765 is available
|
||||
lsof -ti:8765 | xargs kill -9 2>/dev/null
|
||||
|
||||
# Run the test
|
||||
uv run python tests/manual/test_adr004_manual.py --provider nextcloud
|
||||
```
|
||||
|
||||
## Expected Flow
|
||||
|
||||
### 1. Test Script Starts
|
||||
```
|
||||
======================================================================
|
||||
ADR-004 MANUAL OAUTH FLOW TEST
|
||||
======================================================================
|
||||
Provider: nextcloud
|
||||
MCP Server: http://localhost:8001
|
||||
Nextcloud: http://localhost:8080
|
||||
======================================================================
|
||||
|
||||
✓ Generated PKCE challenge: gxQLsYDJ...
|
||||
✓ Started callback server at http://localhost:8765/callback
|
||||
```
|
||||
|
||||
### 2. Open OAuth URL in Browser
|
||||
The script will print:
|
||||
```
|
||||
======================================================================
|
||||
STEP 1: AUTHORIZE THE MCP SERVER
|
||||
======================================================================
|
||||
|
||||
📋 Open this URL in your browser:
|
||||
|
||||
http://localhost:8001/oauth/authorize?response_type=code&...
|
||||
|
||||
📌 What will happen:
|
||||
1. You'll be redirected to Nextcloud/Keycloak login
|
||||
2. Login with username: admin, password: admin
|
||||
3. You'll see a consent screen asking to authorize the MCP server
|
||||
4. Click 'Authorize' or 'Allow'
|
||||
5. You'll be redirected to localhost:8765/callback
|
||||
6. The authorization code will appear in the terminal
|
||||
```
|
||||
|
||||
### 3. Browser Flow
|
||||
1. **Nextcloud Login** - You see the Nextcloud login page
|
||||
2. **Enter Credentials** - admin/admin
|
||||
3. **Consent Screen** - "Authorize Nextcloud MCP Server (jwt) to access your account?"
|
||||
4. **Click Authorize**
|
||||
5. **Redirect Chain**:
|
||||
- Nextcloud redirects to: `http://localhost:8001/oauth/callback?code=...`
|
||||
- MCP server processes the code
|
||||
- MCP server redirects to: `http://localhost:8765/callback?code=mcp-code-...&state=...`
|
||||
- Browser reaches the test script's callback server
|
||||
- You see: "✓ Authorization Successful - You can close this window"
|
||||
|
||||
### 4. Test Script Continues
|
||||
```
|
||||
✓ Received authorization code!
|
||||
Code: mcp-code-xyz...
|
||||
✓ State parameter verified (CSRF protection)
|
||||
|
||||
======================================================================
|
||||
STEP 2: EXCHANGE CODE FOR ACCESS TOKEN
|
||||
======================================================================
|
||||
|
||||
✓ Successfully received access token
|
||||
Token: eyJhbGciOiJSUzI1Ni...
|
||||
Type: Bearer
|
||||
Expires: 3600s
|
||||
|
||||
======================================================================
|
||||
STEP 3: CALL MCP TOOL WITH ACCESS TOKEN
|
||||
======================================================================
|
||||
|
||||
✓ MCP tool call succeeded!
|
||||
Result: {...}
|
||||
|
||||
======================================================================
|
||||
🎉 ADR-004 OAUTH FLOW TEST - SUCCESS
|
||||
======================================================================
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Browser Gets Stuck at "localhost:8765 refused to connect"
|
||||
|
||||
**Problem**: The callback server on port 8765 isn't accessible.
|
||||
|
||||
**Solutions**:
|
||||
1. Check firewall isn't blocking port 8765
|
||||
2. Verify the test script is still running
|
||||
3. Check another process isn't using port 8765:
|
||||
```bash
|
||||
lsof -ti:8765
|
||||
```
|
||||
|
||||
### Browser Shows "localhost:8765 - ERR_CONNECTION_REFUSED"
|
||||
|
||||
**Problem**: The callback server stopped or never started.
|
||||
|
||||
**Solution**:
|
||||
1. Check the test script output - it should say "✓ Started callback server"
|
||||
2. Restart the test script
|
||||
3. Manually test the callback server:
|
||||
```bash
|
||||
curl http://localhost:8765/callback?code=test&state=test
|
||||
```
|
||||
Should return HTML page with "Authorization Successful"
|
||||
|
||||
### "Session not found or expired" Error
|
||||
|
||||
**Problem**: Took too long between steps (>10 minutes).
|
||||
|
||||
**Solution**: Restart the test - sessions expire after 10 minutes.
|
||||
|
||||
### Client ID is None
|
||||
|
||||
**Problem**: OAuth client credentials not loaded.
|
||||
|
||||
**Solution**: Rebuild the MCP server:
|
||||
```bash
|
||||
docker-compose up --build -d mcp-oauth
|
||||
```
|
||||
|
||||
### Nextcloud Shows "Invalid redirect_uri"
|
||||
|
||||
**Problem**: The redirect URI isn't registered for the OAuth client.
|
||||
|
||||
**Solution**: Check registered URIs:
|
||||
```bash
|
||||
docker compose exec db mariadb -u root -ppassword nextcloud -e \
|
||||
"SELECT c.client_identifier, r.redirect_uri FROM oc_oidc_clients c \
|
||||
LEFT JOIN oc_oidc_redirect_uris r ON c.id = r.client_id \
|
||||
WHERE c.name LIKE '%MCP%';"
|
||||
```
|
||||
|
||||
Should show: `http://localhost:8001/oauth/callback`
|
||||
|
||||
## Manual Test Without Script
|
||||
|
||||
If the automated test doesn't work, you can test manually:
|
||||
|
||||
1. **Start callback server manually**:
|
||||
```bash
|
||||
python3 -m http.server 8765
|
||||
```
|
||||
|
||||
2. **Open OAuth URL in browser** (get from test script output or build manually):
|
||||
```
|
||||
http://localhost:8001/oauth/authorize?response_type=code&client_id=test-mcp-client&redirect_uri=http://localhost:8765/callback&scope=openid+profile+email+offline_access&state=TEST&code_challenge=CHALLENGE&code_challenge_method=S256
|
||||
```
|
||||
|
||||
3. **Complete login** at Nextcloud
|
||||
|
||||
4. **Browser should redirect** to `http://localhost:8765/callback?code=mcp-code-...&state=TEST`
|
||||
|
||||
5. **Copy the code** from the URL and exchange it:
|
||||
```bash
|
||||
curl -X POST http://localhost:8001/oauth/token \
|
||||
-d "grant_type=authorization_code" \
|
||||
-d "code=<MCP_CODE_HERE>" \
|
||||
-d "code_verifier=<VERIFIER_HERE>" \
|
||||
-d "redirect_uri=http://localhost:8765/callback" \
|
||||
-d "client_id=test-mcp-client"
|
||||
```
|
||||
|
||||
## Expected Database State After Success
|
||||
|
||||
```bash
|
||||
# Check refresh token was stored
|
||||
docker compose exec mcp-oauth sh -c \
|
||||
"sqlite3 /app/data/tokens.db 'SELECT user_id, created_at FROM refresh_tokens;'"
|
||||
```
|
||||
|
||||
Should show an entry for the authenticated user.

ADR-004 OAuth Flow Test Script
|

Tests the complete Hybrid Flow implementation:
|

1. User initiates OAuth at MCP server /oauth/authorize
|
||||
2. User consents to MCP server access (IdP)
|
||||
3. User consents to MCP server accessing Nextcloud (IdP/Nextcloud)
|
||||
4. MCP server receives master refresh token
|
||||
5. Client receives MCP access token
|
||||
6. Client calls MCP tool
|
||||
7. MCP server exchanges master refresh token for Nextcloud access token
|
||||
8. MCP server fetches data from Nextcloud on behalf of user
|
||||
|
||||
Usage:
|
||||
# Test with Nextcloud OIDC app
|
||||
uv run python tests/manual/test_adr004_oauth_flow.py --provider nextcloud
|
||||
|
||||
# Test with Keycloak
