The Live Wire Between Design and Code

Slack ping from engineering: "Hey, what's the hex code for primary blue?"

You open Figma. The token says #2563EB . You're 80% sure it was #3B82F6 last month. You check the version history. Someone updated it three weeks ago. You dig through Notion to find the decision doc. Twenty minutes gone.

Figma MCP stops this archaeology. It's the live wire between your design system and the AI tools engineers are already using.

MCP (Model Context Protocol) is a continuous feed. Not a one-time export. Not a screenshot. Not a PDF handoff. It's a stream that tells AI coding agents: "Here's the current button radius. Here's the spacing token that just changed. Here's the component that was published two minutes ago."

Think of it like a universal translator that never stops listening. Your design system speaks Figma. Your AI coding agent speaks Claude or GPT. MCP sits between them, constantly translating live context without anyone needing to export, document, or manually sync anything.

This matters for vibe coding. When an engineer (or an AI agent) generates code from a rough wireframe, MCP ensures it uses your actual design tokens. Not approximate values. Not "close enough blue." The real var(--color-primary-600) and border-radius: 8px from your live system.

The gap between design and code has always been about translation lag. Someone changes a token. Someone else forgets to update the spec. Engineering builds from stale information. MCP makes that gap disappear by streaming the source of truth continuously.

You're not handing off files anymore. You're sharing living context.
