verification against CyberArk Identity JWKS endpoint, and UserSessionManager for per-user session lifecycle with SHA-256 keying, TTL expiry, max_sessions limits, and graceful shutdown.

Requiring users to configure it added unnecessary setup friction. This reduces OAuth configuration from 2 required env vars to 1 (`CYBERARK_IDENTITY_TENANT_URL`). The constant is defined in token_verifier.py and used for JWT audience validation. 278 tests passing, zero regression. --- .env.example | 5 +++- CLAUDE.md | 3 +-- README.md | 2 -- docs/API_REFERENCE.md | 1 - docs/ARCHITECTURE.md | 3 +-- docs/CYBERARK_IDENTITY_SETUP.md | 31 ++++------------------- src/mcp_privilege_cloud/mcp_server.py | 9 ++----- src/mcp_privilege_cloud/token_verifier.py | 14 +++++----- tests/test_oauth_integration.py | 6 +---- tests/test_token_verifier.py | 28 ++++++++------------ 10 files changed, 31 insertions(+), 71 deletions(-) diff --git a/.env.example b/.env.example index fef6104..1d06190 100644 --- a/.env.example +++ b/.env.example @@ -1,7 +1,10 @@ # CyberArk Privilege Cloud Configuration # Copy this file to .env and fill in your actual values -# Required: Service account credentials +# OAuth per-user mode (recommended) +CYBERARK_IDENTITY_TENANT_URL=https://your-tenant.id.cyberark.cloud + +# OR legacy service account mode CYBERARK_CLIENT_ID=your-service-account-username CYBERARK_CLIENT_SECRET=your-service-account-password diff --git a/CLAUDE.md b/CLAUDE.md index 84ec85c..6d3f3c3 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -98,7 +98,7 @@ Use context7 resolve-library-id and get-library-docs tools: **Current Status**: ✅ **OAUTH + STREAMABLE HTTP MIGRATION COMPLETE** - All implementation phases complete: Streamable HTTP transport, token auth bridge, token verifier + session manager, full OAuth wiring, and documentation. **Last Updated**: February 25, 2026 -**Recent Achievement**: Full OAuth per-user authentication pipeline: CyberArkTokenVerifier (JWKS), UserSessionManager (per-user sessions), dual-mode FastMCP (OAuth + legacy), per-user session resolution in execute_tool(). 277 passing tests with zero regression. +**Recent Achievement**: Full OAuth per-user authentication pipeline: CyberArkTokenVerifier (JWKS), UserSessionManager (per-user sessions), dual-mode FastMCP (OAuth + legacy), per-user session resolution in execute_tool().

Specifically: + +1. **The built-in `__idaptive_cybr_user_oidc` app** — Cannot modify redirect URIs, so it can't support claude.ai's callback URL. + +2. **Custom OIDC apps** — Can be created, but CyberArk Identity returns `invalid_client` after user authentication regardless of: + - Client ID type set to "Anything" + - App set to "Confidential" with matching `client_id` and `client_secret` + - Redirect URI properly registered + - All standard OAuth parameters present (response_type, code_challenge, scope, etc.) + +3. **The `invalid client creds` error** occurs AFTER user authentication, during the authorization code issuance step. This suggests CyberArk Identity's OIDC implementation has specific requirements for client validation that differ from standard OAuth 2.1. + +### Possible Explanations + +- CyberArk Identity may require a specific client authentication method during the authorization request (not just token exchange) +- The OIDC app may need additional configuration beyond what's visible in the admin UI (e.g., API-level settings, specific OAuth profile, or trust relationships) +- The `client_id` format expected by CyberArk Identity for custom apps may differ from what we're sending +- CyberArk Identity may not fully support the public/PKCE flow that MCP clients expect, or may require additional parameters + +## Files Modified + +| File | Purpose | +|------|---------| +| `src/mcp_privilege_cloud/mcp_server.py` | Added `_fetch_oidc_discovery()`, `_build_oauth_metadata()`, `_build_dcr_response()`, `_register_oauth_routes()` with custom routes for `/.well-known/oauth-authorization-server` and `/register` | +| `src/mcp_privilege_cloud/token_verifier.py` | Made `CYBERARK_OIDC_APP_ID` configurable via env var (default: `mcpprivilegecloud`) | +| `tests/test_oauth_metadata.py` | 16 tests covering OIDC discovery fetching/caching, metadata building, DCR response, route registration | +| `CLAUDE.md` | Updated status and test file listings | + +## Environment Variables (New/Changed) + +| Variable | Purpose | Default | +|----------|---------|---------| +| `CYBERARK_OIDC_APP_ID` | OIDC app ID for URL paths and token audience validation | `mcpprivilegecloud` | +| `CYBERARK_CLIENT_ID` | OAuth client_id returned in DCR response | Falls back to `CYBERARK_OIDC_APP_ID` | +| `CYBERARK_CLIENT_SECRET` | OAuth client_secret returned in DCR (confidential client) | None (public client) | + +## Next Steps to Unblock + +1. **CyberArk Identity investigation** — Determine the exact OIDC app configuration required for custom apps to issue authorization codes.

Tests core functionality across all services -- `generate_test_report()` - Human-readable comprehensive test report - -### Error Handling and Diagnostics - -The testing script provides detailed error categorization: -- **Authentication Issues**: Invalid credentials, token problems -- **Permission Issues**: Insufficient CyberArk permissions -- **Network Issues**: Connectivity, timeout problems -- **Tool Issues**: Invalid parameters, tool execution failures - -### Integration with Existing Tests +For interactive testing of the MCP server against a live CyberArk environment, use the MCP Inspector: ```bash -# Run all testing approaches together -uv run pytest # Unit/integration tests (144 tests) -python test_mcp_cli.py validation_suite # MCP CLI validation -python test_mcp_cli.py generate_report # Comprehensive report -``` - -### LLM Usage Examples - -**Health Check:** -```python -tester = MCPTester() -health = tester.test_server_health() -if health["overall_status"] == "healthy": - print("✅ Server ready for operations") -else: - print("❌ Issues found:", health["issues"]) -``` - -**Tool Discovery:** -```python -capabilities = tester.discover_tool_capabilities() -print(f"Total tools: {capabilities['total_tools']}") -for category, tools in capabilities["tools_by_category"].items(): - print(f"{category}: {len(tools)} tools") -``` +# Run MCP Inspector +npx @modelcontextprotocol/inspector -**Validation Suite:** -```python -validation = tester.run_basic_validation_suite() -print(f"Success rate: {validation['success_rate']:.1f}%") -print(f"Tests passed: {validation['tests_passed']}/{validation['tests_passed'] + validation['tests_failed']}") -``` - -This approach enables LLMs to perform comprehensive, real-time validation of the MCP server functionality with actual CyberArk environments. \ No newline at end of file +# Run all pytest tests (292 tests) +uv run pytest +``` \ No newline at end of file diff --git a/src/mcp_privilege_cloud/exceptions.py b/src/mcp_privilege_cloud/exceptions.py index 21da2cb..dd5a77b 100644 --- a/src/mcp_privilege_cloud/exceptions.py +++ b/src/mcp_privilege_cloud/exceptions.py @@ -40,11 +40,6 @@ def __init__(self, message: str, status_code: Optional[int] = None): self.status_code = status_code -class AuthenticationError(Exception): -
