OpenAPI specifications => MCP (Model Context Protocol) tools
This project helps developers quickly integrate existing OpenAPI specifications into MCP (Model Context Protocol) servers. It takes an OpenAPI specification as input and outputs a list of tools and a tool caller function, which can then be used to define and execute these tools within an MCP server. This is designed for software developers building applications that need to communicate with or expose services via the Model Context Protocol.

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.
