Turns existing FastAPI routes and custom Python functions into MCP tools, exposing them over ASGI, SSE, or stdio so desktop and chat AI clients can call them with native dependency-injected auth, progressive tool discovery, and self-correcting error responses. It also serves interactive in-chat HTML/JS widgets and a built-in browser inspector for testing tools without external CLIs.
Automatically converts any OpenAPI specification into an MCP server, exposing all HTTP endpoints as callable tools with support for various authentication methods and request types.
Enables building agent-ready APIs that expose tools as both HTTP and MCP endpoints from a single server definition, with automatic OpenAPI, discovery docs, and interactive API reference.
