Plumb (plumb-mcp) — the AI-native design engineering platform

     

⭐ If Plumb saves you tokens — or designs you a page — star it on GitHub so others can find it.

Plumb is an AI-native design engineering platform, shipped as a single MCP server. Point it at a Figma file or a live website and it normalises either one into the same semantic design graph — deduped tokens, flexbox-resolved layout, conservative role labels (nav / hero / card …) — that your coding agent can build from and a verification loop can grade. Point it at a one-line prompt instead and it becomes an AI design director: it researches best-in-class references, extracts a brand, and generates a full, on-brand Figma file on your canvas, then critiques its own render until it clears the bar.

Design → code (Figma or the live web, verified, not vibes)  •  prompt → design (research → brand → generate → critique)  •  one semantic design graph underneath both. MCP-native — works with Claude Code, Cursor, Windsurf, or any agent that speaks Model Context Protocol.

Built for coding agents — Claude Code, Cursor, Windsurf, anything MCP-compatible. Design engineering, agent-native: no dashboard, no separate app to babysit, no human shuttling pixels between Figma and an editor. It reads Figma through a desktop-app plugin (no REST rate limits, works on every plan including Free), reads any live website through headless Chrome, writes new designs back into Figma through the same plugin, and returns compact normalised specs instead of the multi-hundred-thousand-token JSON the Figma API emits.

Why "design engineering platform," not "Figma converter"

Most Figma MCP servers — and most figma-to-code tools generally — are one shape in, one shape out: Figma JSON in, one framework's code out, done. Plumb's architecture is a hub, not a pipe:

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
