GraphQL MCP Server

# GraphQL MCP Server - Project Status ## Current Status: Production Ready The GraphQL MCP Server is now fully functional, production-ready, and implemented in TypeScript with strong typing. It successfully implements the Model Context Protocol (MCP) for seamless integration with Claude Desktop, enabling dynamic access to any GraphQL API. ## Key Milestones Achieved 1. ✅ **TypeScript Implementation**: Completely rewritten in TypeScript with proper type definitions 2. ✅ **Dynamic Schema Introspection**: Server successfully introspects any GraphQL API and generates appropriate tools 3. ✅ **Full MCP Protocol Support**: Implements all required MCP endpoints with proper response formatting 4. ✅ **Smart Query Generation**: Builds optimized GraphQL queries with appropriate field selection 5. ✅ **Complex Input Handling**: Properly processes input objects and variable types 6. ✅ **Error Handling**: Robust error handling and propagation to client 7. ✅ **MCP-Compliant Response Format**: Returns results in the format expected by Claude Desktop ## Recent Updates - **TypeScript Conversion**: Completely rewritten in TypeScript with proper type definitions - **Strong Typing**: Added comprehensive type definitions for all components - **Development Workflow**: Added improved development scripts for better developer experience - **Documentation Update**: Updated documentation to reflect TypeScript conversion ## Type Safety Benefits The TypeScript implementation provides significant benefits over the previous JavaScript version: - **Compile-time Error Detection**: Catches errors during development before they reach users - **Better IDE Support**: Improved code completion and type hints - **Self-documenting Code**: Types serve as documentation for the codebase - **Safer Refactoring**: Types ensure changes don't break existing functionality - **Improved Maintainability**: Easier to understand and modify the codebase ## Known Limitations - **Authentication Methods**: Currently only supports Bearer token authentication - **Field Selection**: Uses a heuristic approach that may not be optimal for all schemas - **GraphQL Directives**: Limited support for GraphQL directives ## Next Steps 1. **Enhanced Authentication**: Support additional authentication methods 2. **Schema Caching Options**: Add configurable caching strategies 3. **Advanced Mutation Features**: Add support for complex mutation input types and recursive fragments 4. **Testing Suite**: Develop comprehensive tests for different GraphQL APIs 5. **API Documentation**: Generate API documentation from TypeScript types ## Deployment Status The server has been successfully tested with: - Claude Desktop (macOS and Windows) - Countries GraphQL API - GitHub GraphQL API - Various other public GraphQL endpoints ## Feedback and Contributions We welcome feedback and contributions to improve the GraphQL MCP Server.
