FastAPI OpenAPI
Enables FastAPI applications to expose their endpoints as an AI-friendly, introspectable server using the Model Context Protocol.
About
This FastAPI library transforms your API documentation into an AI-friendly, introspectable server compatible with the Model Context Protocol (MCP). It allows AI agents, LLMs, and development tools like Cursor and GitHub Copilot to seamlessly discover, understand, and interact with your FastAPI endpoints. By providing detailed, resolved OpenAPI documentation and implementing the latest MCP Streamable HTTP transport, it facilitates next-generation AI workflows for API interaction and development.
