OpenAPI specifications => MCP (Model Context Protocol) tools
Automatically transforms OpenAPI endpoints into MCP-compatible tools with built-in HTTP client abstraction, enabling MCP servers to expose REST APIs through the protocol's tool interface. The `Converter` class parses specifications and generates both tool definitions and a callable handler for executing requests, while supporting custom HTTP clients (axios, etc.) and configuration like baseURL and headers. Designed to integrate directly with MCP SDK's stdio transport and server patterns for rapid server development.
About mcp-openapi
ReAPI-com/mcp-openapi
OpenAPI specification MCP server.
Loads and dereferences multiple OpenAPI specifications from a directory, exposing API operations and schemas through MCP tools for LLM-powered IDE integration in Cursor. Implements a catalog-based architecture with search and lookup capabilities across specifications, using custom `x-spec-id` fields to disambiguate overlapping endpoints and schemas between services. Integrates directly into Cursor via `.cursor/mcp.json` configuration and provides tools for dynamic catalog refresh and semantic operation/schema discovery.
