OpenAPI-MCP provides a bridge between Claude and any REST API that publishes an OpenAPI specification. Built by Roger Gujord, this implementation automatically generates MCP tools from OpenAPI endpoints, handling parameter validation, OAuth authentication, and proper JSON-RPC 2.0 response formatting. It features dry-run capabilities for testing requests without making actual API calls, detailed error handling, and dynamic help documentation for each endpoint. The server is particularly valuable for workflows requiring access to third-party APIs directly within Claude conversations, eliminating the need to manually implement individual API integrations.
