Figma MCP Server

A Model Context Protocol (MCP) server that provides integration with Figma's API through Claude and other MCP-compatible clients. Currently supports read-only access to Figma files and projects, with server-side architecture capable of supporting more advanced design token and theme management features (pending Figma API enhancements or plugin development).

Project Status

Current Progress

• ✅ Core Implementation: Successfully built a TypeScript server following the Model Context Protocol (MCP)

• ✅ Claude Desktop Integration: Tested and functional with Claude Desktop

• ✅ Read Operations: Working get-file and list-files tools for Figma file access

• ✅ Server Architecture: Caching system, error handling, and stats monitoring implemented

• ✅ Transport Protocols: Both stdio and SSE transport mechanisms supported

Potential Full Functionality

The server has been designed with code to support these features (currently limited by API restrictions):

• Variable Management: Create, read, update, and delete design tokens (variables)

• Reference Handling: Create and validate relationships between tokens

• Theme Management: Create themes with multiple modes (e.g., light/dark)

• Dependency Analysis: Detect and prevent circular references

• Batch Operations: Perform bulk actions on variables and themes

With Figma plugin development or expanded API access, these features could be fully enabled.

Features

• 🔑 Secure authentication with Figma API

• 📁 File operations (read, list)

• 🎨 Design system management

  • Variable creation and management

  • Theme creation and configuration

  • Reference handling and validation

• 🚀 Performance optimized

  • LRU caching

  • Rate limit handling

  • Connection pooling

• 📊 Comprehensive monitoring

  • Health checks

  • Usage statistics

  • Error tracking

Prerequisites

• Node.js 18.x or higher

• Figma access token with appropriate permissions

• Basic understanding of MCP (Model Context Protocol)

Installation

Configuration

1. Create a .env file based on .env.example:

2. For Claude Desktop integration:

The server can be configured in your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

Important Notes:

• Use ABSOLUTE paths, not relative paths

• On Windows, use double backslashes (\\) in paths

• Restart Claude Desktop after making configuration changes

Usage

Basic Usage

Available Tools

1. get-file

   • Retrieve Figma file details

   { "name": "get-file", "arguments": { "fileKey": "your_file_key" } }

2. list-files

   • List files in a Figma project

   { "name": "list-files", "arguments": { "projectId": "your_project_id" } }

3. create-variables

   • Create design system variables

   { "name": "create-variables", "arguments": { "fileKey": "your_file_key", "variables": [ { "name": "primary-color", "type": "COLOR", "value": "#0066FF" } ] } }

4. create-theme

   • Create and configure themes

   { "name": "create-theme", "arguments": { "fileKey": "your_file_key", "name": "Dark Theme", "modes": [ { "name": "dark", "variables": [ { "variableId": "123", "value": "#000000" } ] } ] } }

Error Handling

The server provides detailed error messages and proper error codes:

• Invalid token: 403 with specific error message

• Rate limiting: 429 with reset time

• Validation errors: 400 with field-specific details

• Server errors: 500 with error tracking

Limitations & Known Issues

API Restrictions

1. Read-Only Operations

   • Limited to read-only operations due to Figma API restrictions

   • Personal access tokens only support read operations, not write

   • Cannot modify variables, components, or styles through REST API with personal tokens

   • Write operations would require Figma plugin development instead

2. Rate Limiting

   • Follows Figma API rate limits

   • Implement exponential backoff for better handling

3. Cache Management

   • Default 5-minute TTL

   • Limited to 500 entries

   • Consider implementing cache invalidation hooks

4. Authentication

   • Only supports personal access tokens

   • No support for team-level permissions or collaborative editing

   • OAuth implementation planned for future

5. Technical Implementation

   • Requires absolute paths in configuration

   • Must compile TypeScript files before execution

   • Requires handling both local and global module resolution

Troubleshooting

See TROUBLESHOOTING.md for a comprehensive troubleshooting guide.

Common Issues

1. JSON Connection Errors

   • Use absolute paths in Claude Desktop configuration

   • Ensure the server is built (npm run build)

   • Verify all environment variables are set

2. Authentication Issues

   • Verify your Figma access token is valid

   • Check the token has required permissions

   • Ensure the token is correctly set in configuration

3. Server Not Starting

   • Check Node.js version (18.x+ required)

   • Verify the build exists (dist/index.js)

   • Check Claude Desktop logs:

     • macOS: ~/Library/Logs/Claude/mcp*.log

     • Windows: %APPDATA%\Claude\logs\mcp*.log
