Claude Talk to Figma MCP

A Model Context Protocol (MCP) plugin that allows Claude Desktop and other AI tools (GitHub Copilot, Cursor, etc.) to interact directly with Figma, enabling powerful AI-assisted design capabilities.

Important: This project is based on cursor-talk-to-figma-mcp by Sonny Lazuardi. It has been adapted to work with Claude Desktop and expanded with additional tools. Original credit belongs to Sonny Lazuardi ❤️

⚡ Installation

1. Prerequisites

• Claude Desktop or Cursor + Figma Desktop + Bun installed

2. Setup

git clone https://github.com/arinspunk/claude-talk-to-figma-mcp.git
cd claude-talk-to-figma-mcp
bun install

• macOS/Linux: bun run build
• Windows: bun run build:win

3. AI client configuration

Option 1: DXT Package (Claude Desktop only)

1. Download: Get the latest claude-talk-to-figma-mcp.dxt from releases
2. Install: Double-click the .dxt file → Claude Desktop installs automatically

Option 2: JSON (Claude Desktop or Cursor)

• Claude Desktop: Run bun run configure-claude (restart Claude Desktop)
• Cursor:
  1. Go to Cursor Settings → Tools & Integrations
  2. Click "New MCP Server" to open mcp.json config ()
  3. Add this configuration:

  {
    "mcpServers": {
      "ClaudeTalkToFigma": {
        "command": "bunx",
        "args": ["claude-talk-to-figma-mcp@latest"]
      }
    }
  }
  

  4. Save the file ()

4. Setup Figma Plugin (Required for all methods)

Import src/claude_mcp_plugin/manifest.json in Figma → Menu → Plugins → Development

4. First Connection

1. Start server: bun socket (verify at http://localhost:3055/status)
2. Connect plugin: Open Claude MCP Plugin in Figma → copy channel ID
3. Test: Ask your AI client: "Talk to Figma, channel {channel-ID}"

✅ Success: Your AI should confirm connection and you can start designing!

🚀 Core Concepts

How It Works

Claude Desktop ↔ MCP Server ↔ WebSocket Server ↔ Figma Plugin

Simple: Claude sends design commands → Figma executes them in real-time
Bidirectional: Get info from Figma, create/modify elements, manage components

Key Capabilities

• Document Interaction: Analyze designs, get selections, export assets
• Element Creation: Shapes, text, frames with full styling control
• Smart Modifications: Colors, effects, auto-layout, responsive design
• Text Mastery: Advanced typography, font loading, text scanning
• Component Integration: Local and team library components

🛠️ Usage Patterns

Getting Started with AI Design

1. Make Claude a UX expert: 🎨
2. Connect to your project: "Talk to Figma, channel {channel-ID}"
3. Start designing: "Create a mobile app login screen with modern styling"

Effective Prompting Examples

✅ Good: "Create a dashboard with a sidebar navigation, header with user profile, and main content area with card-based metrics"

✅ Good: "Redesign this button component with hover states and better contrast ratios"

❌ Avoid: "Make it look nice" (too vague)

Building DXT Package (Developers)

To create your own DXT package:

npm run build:dxt    # Builds TypeScript and packages DXT

This creates claude-talk-to-figma-mcp.dxt ready for distribution.

🧪 Testing & Quality Assurance

Automated Testing

bun run test            # Run all tests

bun run test:coverage   # Coverage report

Integration Testing

bun run test:integration  # Guided end-to-end testing

Manual Verification Checklist

• WebSocket server starts on port 3055
• Figma plugin connects and generates channel ID
• AI tool recognizes "ClaudeTalkToFigma" MCP (Claude Desktop, Cursor, etc.)
• Basic commands execute (create rectangle, change color)
• Error handling works (invalid commands, timeouts)
• Channel communication works between AI tool and Figma

🐛 Troubleshooting & Support

Connection Issues

• "Can't connect to WebSocket": Ensure bun socket is running
• "Plugin not found": Verify plugin import in Figma Development settings
• "MCP not available":
  • Claude Desktop: Run bun run configure-claude and restart Claude
  • Cursor IDE: Check MCP configuration in mcp.json file
  • Other AI tools: Verify MCP integration settings

Execution Problems

• "Command failed": Check Figma development console for errors
• "Font not found": Use load_font_async to verify font availability
• "Permission denied": Ensure you have edit access to the Figma document
• "Timeout errors": Complex operations may need retry

Performance Issues

• Slow responses: Large documents may require more processing time
• Memory usage: Close unused Figma tabs, restart if necessary
• WebSocket disconnects: Server auto-reconnects, restart if persistent

Common Solutions

1. Restart sequence: Stop server → Close AI tool → Restart both
2. Clean reinstall: Delete node_modules → bun install → bun run build
3. Check logs: Server terminal shows detailed error messages
4. Update fonts: Some team fonts require manual loading in Figma
5. Configuration check: Verify MCP setup in your AI tool's settings
6. Port conflicts: Ensure port 3055 is not used by other applications

Design Principles:

• MCP Server: Business logic, validation, default values
• WebSocket Server: Message routing and protocol translation
• Figma Plugin: Pure command executor in Figma context

Benefits:

• Clear separation of concerns
• Easy testing and maintenance
• Scalable architecture for additional tools
