About redoc
Redoc is an open source tool for generating API reference documentation from OpenAPI definitions, formerly known as Swagger. It lives in the JavaScript and TypeScript ecosystem, ships under the MIT license, and is published on npm as the redoc package. By default it renders a responsive three panel layout: a left panel holding the search bar and navigation menu, a central panel holding the documentation itself, and a right panel showing request and response examples.

About fastapi_mcp
FastAPI MCP is an MIT licensed Python library from Tadata that exposes the endpoints of an existing FastAPI application as Model Context Protocol (MCP) tools, so MCP clients such as Claude and Cursor can call a team's own API, and it is built for Python backend developers who already run FastAPI services and want agent access without hand writing a separate MCP server.
