design-extract vs fastapi_mcp

design-extract: designlang is a unique tool that crawls any website with a headless browser to extract comprehensive computed styles, layout patterns, motion language, component anatomy, and brand voice from the live DOM. It generates over 17 distinct output files, including AI-optimized markdown, Tailwind config, React themes, and Figma variables, enabling precise capture and translation of a site's visual DNA. Users can leverage it for tasks like design system scoring, codebase drift-checking against live sites, and visual comparison of multiple URLs or brands.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.

When to choose:
  • You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
  • You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.
When to skip:
  • You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
  • You need an actively updated repository (last push was November 2025).
