Figma Dev Mode MCP — build from the actual design

Figma's Dev Mode server (runs locally from the desktop app): the agent reads the selected frame's structure, variables, and components — so UI work starts from the real spec instead of a screenshot description.

A vetted listing, not an install — add the config to your MCP client yourself. CoSquared never writes MCP config.

Why this one

Frontend task framing is only as good as the spec in context — reading the design file directly removes the lossiest translation step.

How to use it

  1. 1Select the exact frame before asking for implementation
  2. 2Ask for the design's variables/tokens, not hardcoded values

Client config

Placeholders only — bring your own values

{
  "mcpServers": {
    "figma": {
      "url": "http://127.0.0.1:3845/mcp"
    }
  }
}

Security notes

Runs locally out of the Figma desktop app and exposes whatever file is open/selected — including unreleased designs. Requires a seat with Dev Mode; nothing leaves your machine except what the agent quotes into its own context.
