A tool that converts OpenAPI specifications to MCP server
This tool helps developers quickly create Model Context Protocol (MCP) servers from existing OpenAPI specifications. It takes your OpenAPI spec and generates a server that can act as a proxy, translating requests from AI agents and other MCP clients into calls to your original REST API. This is ideal for developers building AI agents or integrating existing APIs into MCP-compatible systems.

Turns any OpenAPI/Swagger API into an MCP server. One MCP tool per endpoint, Streamable HTTP - for AI clients calling your REST API.
This project helps developers integrate their existing REST APIs with AI clients that use the Model Context Protocol (MCP). It takes an OpenAPI/Swagger specification as input and automatically generates a dedicated MCP tool for each API operation. The output is an MCP server that translates AI client requests into standard HTTP calls to your backend API, making your API accessible to AI agents without manual integration.
