Figma MCP Builds Exactly What You Ask – Nothing More - The Miners Real-world experiments with Figma to code: 2 different approaches and what actually works, where it falls short.

We tested Figma's MCP for design-to-code. It's literal: ask for HTML, get one file. Ask for React, everything goes in App.jsx. Works well if you're specific, but don't expect best practices. Visual output is accurate, though.
