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.
