**61 tools tested and verified** in deployed environment - **Multi-client concurrent access** proven functional - **Health monitoring** integrated with container orchestration - **Build process optimized** for modular architecture - **Documentation auto-sync** working across all definition files ## Known Issues 1. No pagination support for list operations, which may result in incomplete results for large repositories 2. No caching mechanism for API responses 3. No support for GraphQL API (only REST API v4) 4. Limited test coverage for the new functionality
