Transforms any OpenAPI-specified API into a fully functional Model Context Protocol server.
Sponsored
Mcpgen converts existing APIs, defined by an OpenAPI 3.x specification, into a Model Context Protocol (MCP) server. It operates as a single Go binary with zero configuration, streamlining the process of making any API accessible via MCP. The tool parses your OpenAPI spec, maps each API endpoint to a uniquely named MCP tool (e.g., `get_v1_users`), and serves these tools over standard I/O or Server-Sent Events (SSE). When an MCP tool is invoked, Mcpgen transparently makes the corresponding HTTP request to the original API and returns the response, effectively bridging the gap between traditional REST APIs and the Model Context Protocol.
