openapi-mcp-generator and mcp-openapi
These are complements: the generator (A) creates MCP servers from OpenAPI specs, while the server (B) exposes OpenAPI specs as an MCP server—one generates MCP implementations, the other consumes/serves specifications as MCP.
About openapi-mcp-generator
harsha-iiiv/openapi-mcp-generator
A tool that converts OpenAPI specifications to MCP server
Automatically generates Zod-validated TypeScript MCP servers that proxy REST APIs, supporting multiple transports (stdio, SSE, StreamableHTTP) and authentication schemes (API keys, OAuth2, Bearer tokens). The tool produces fully typed, scaffolded Node.js projects with built-in HTML test clients for web-based transports, enabling AI agents to interact with existing APIs through the Model Context Protocol.
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.
