From babd60e08b66f9b0e3d0922f9728babb61d6e30e Mon Sep 17 00:00:00 2001 From: Chris Coutinho Date: Mon, 3 Nov 2025 02:18:30 +0100 Subject: [PATCH] feat: Implement ADR-004 Hybrid Flow with comprehensive integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 --- docs/ADR-004-mcp-application-oauth.md | 42 ++ nextcloud_mcp_server/app.py | 55 +- nextcloud_mcp_server/auth/oauth_routes.py | 544 ++++++++++++++++++ .../auth/refresh_token_storage.py | 241 ++++++++ pyproject.toml | 3 +- tests/manual/README.md | 47 ++ tests/manual/TESTING_INSTRUCTIONS.md | 203 +++++++ tests/manual/test_adr004_manual.py | 319 ++++++++++ tests/manual/test_adr004_oauth_flow.py | 375 ++++++++++++ tests/server/oauth/test_adr004_hybrid_flow.py | 360 ++++++++++++ uv.lock | 14 + 11 files changed, 2198 insertions(+), 5 deletions(-) create mode 100644 nextcloud_mcp_server/auth/oauth_routes.py create mode 100644 tests/manual/README.md create mode 100644 tests/manual/TESTING_INSTRUCTIONS.md create mode 100644 tests/manual/test_adr004_manual.py create mode 100644 tests/manual/test_adr004_oauth_flow.py create mode 100644 tests/server/oauth/test_adr004_hybrid_flow.py diff --git a/docs/ADR-004-mcp-application-oauth.md b/docs/ADR-004-mcp-application-oauth.md index 861b2b7..f1ec1c3 100644 --- a/docs/ADR-004-mcp-application-oauth.md +++ b/docs/ADR-004-mcp-application-oauth.md @@ -1243,6 +1243,48 @@ The **Hybrid Flow** solves the critical problem of getting the master refresh to This architecture follows industry best practices for federated systems and positions the MCP server as a secure token broker in an enterprise identity ecosystem. +## Testing + +The ADR-004 Hybrid Flow is fully tested via automated integration tests: + +### Integration Tests + +```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 +``` + +**Test Coverage:** +- `test_adr004_hybrid_flow_connection`: Verifies MCP session establishment with hybrid flow token +- `test_adr004_hybrid_flow_tool_execution`: Tests complete flow including tool execution +- `test_adr004_hybrid_flow_multiple_operations`: Validates persistent access without re-authentication + +**What the tests verify:** +1. ✅ PKCE code challenge/verifier flow +2. ✅ MCP server intercepts OAuth callback and stores master refresh token +3. ✅ Client receives MCP access token (not master token) +4. ✅ MCP session establishment with hybrid flow token +5. ✅ Tool execution using stored refresh tokens (on-behalf-of pattern) +6. ✅ Multiple operations without re-authentication + +### Test Implementation + +The tests use Playwright automation to complete the OAuth flow: +1.
