Figma MCP Bridge

While other amazing Figma MCP servers like Figma-Context-MCP exist, one issues is the API limiting for free users.

The limit for free accounts is 6 requests per month, yes per month.

Figma MCP Bridge is a solution to this problem. It is a plugin + MCP server that streams live Figma document data to AI tools without hitting Figma API rate limits, so its Figma MCP for the rest of us ✊

Demo

Watch a demo of building a UI in Cursor with Figma MCP Bridge

Quick Start

1. Add the MCP server to your favourite AI tool

Add the following to your AI tool's MCP configuration (e.g. Cursor, Windsurf, Claude Desktop):

{
  "figma-bridge": {
    "command": "npx",
    "args": ["-y", "@gethopp/figma-mcp-bridge"]
  }
}

That's it — no binaries to download or install.

2. Add the Figma plugin

Download the plugin from the latest release page, then in Figma go to Plugins > Development > Import plugin from manifest and select the manifest.json file from the plugin/ folder.

3. Start using it 🎉

Open a Figma file, run the plugin, and start prompting your AI tool. The MCP server will automatically connect to the plugin.

Local development

1. Clone this repository locally

git clone [email protected]:gethopp/figma-mcp-bridge.git

2. Build the server

cd server && npm install && npm run build

3. Build the plugin

cd plugin && bun install && bun run build

4. Add the MCP server to your favourite AI tool

For local development, add the following to your AI tool's MCP config:

{
  "figma-bridge": {
    "command": "node",
    "args": ["/path/to/figma-mcp-bridge/server/dist/index.js"]
  }
}

How it works

There are two main components to the Figma MCP Bridge:

1. The Figma Plugin

The Figma plugin is the user interface for the Figma MCP Bridge. You run this inside the Figma file you want to use the MCP server for, and its responsible for getting you all the information you need.

2. The MCP Server

The MCP server is the core of the Figma MCP Bridge. As the Figma plugin connects with the MCP server via a WebSocket connection, the MCP server is responsible for:

• Handling WebSocket connections from the Figma plugin
• Forwarding tool calls to the Figma plugin
• Routing responses back to the Figma plugin
• Handling leader election (as we can have only one WS connection to an MCP server at a time)
