Plumb MCP

Plumb MCP is a local, open-source server that normalizes Figma files and live websites into a shared semantic design graph. It enables agents to extract design specs, generate deterministic React code, and verify pixel-perfect matches via a verification loop. Alternatively, it can generate on-brand Figma pages from prompts using a companion plugin, avoiding REST API rate limits and token caps.
