# 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
```bash
npm install figma-mcp-server
```
## Configuration
1. Create a `.env` file based on `.env.example`:
```env
# Figma API Access Token
FIGMA_ACCESS_TOKEN=your_figma_token
# Server Configuration
MCP_SERVER_PORT=3000
# Debug Configuration
DEBUG=figma-mcp:*
```
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`
```json
{
"mcpServers": {
"figma": {
"command": "node",
"args": ["/ABSOLUTE/PATH/TO/figma-mcp-server/dist/index.js"],
"env": {
"FIGMA_ACCESS_TOKEN": "your_token_here"
}
}
}
}
```
**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
```javascript
import { startServer } from 'figma-mcp-server';
const server = await startServer(process.env.FIGMA_ACCESS_TOKEN);
```
### Available Tools
1. **get-file**
- Retrieve Figma file details
```javascript
{
"name": "get-file",
"arguments": {
"fileKey": "your_file_key"
}
}
```
2. **list-files**
- List files in a Figma project
```javascript
{
"name": "list-files",
"arguments": {
"projectId": "your_project_id"
}
}
```
3. **create-variables**
- Create design system variables
```javascript
{
"name": "create-variables",
"arguments": {
"fileKey": "your_file_key",
"variables": [
{
"name": "primary-color",
"type": "COLOR",
"value": "#0066FF"
}
]
}
}
```
4. **create-theme**
- Create and configure themes
```javascript
{
"name": "create-theme",
"arguments": {
"fileKey": "your_file_key",
"name": "Dark Theme",
"modes": [
{
"name": "dark",
"variables": [
{
"variableId": "123",
"value": "#000000"
}
]
}
]
}
}
```
## API Documentation
### Server Methods
- `startServer(figmaToken: string, debug?: boolean, port?: number)`
- Initializes and starts the MCP server
- Returns: Promise<MCPServer>
### Tool Schemas
All tool inputs are validated using Zod schemas:
```typescript
const CreateVariablesSchema = z.object({
fileKey: z.string(),
variables: z.array(z.object({
name: z.string(),
type: z.enum(['COLOR', 'FLOAT', 'STRING']),
value: z.string(),
scope: z.enum(['LOCAL', 'ALL_FRAMES'])
}))
});
```
## 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](examples/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`
