Figma MCP Server

A TypeScript server implementing the Model Context Protocol (MCP) for the Figma API, enabling standardized context provision for LLMs.

Overview

This server provides MCP-compliant access to Figma resources, allowing LLM applications to seamlessly integrate with Figma files, components, and variables. It implements the full MCP specification while providing specialized handlers for Figma's unique resource types.

Key Features

MCP Resource Handlers
- Figma files access and manipulation
- Variables and components management
- Custom URI scheme (figma:///)
Robust Implementation
- Type-safe implementation using TypeScript
- Request validation using Zod schemas
- Comprehensive error handling
- Token validation and API integration
- Batch operations support

Installation

npm install @modelcontextprotocol/sdk
npm install

Configuration

Set up your Figma access token:

export FIGMA_ACCESS_TOKEN=your_access_token

Configure the server (optional):
```
export MCP_SERVER_PORT=3000
```

Usage

Starting the Server

npm run start

Using as an MCP Server

The server implements the Model Context Protocol, making it compatible with any MCP client. It supports both stdio and SSE transports:

stdio Transport

figma-mcp-server < input.jsonl > output.jsonl

SSE Transport

figma-mcp-server --transport sse --port 3000

Client Integration

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";

// Initialize the client
const transport = new StdioClientTransport({
  command: "path/to/figma-mcp-server",
});

const client = new Client({
  name: "figma-client",
  version: "1.0.0",
}, {
  capabilities: {
    resources: {} // Enable resources capability
  }
});

await client.connect(transport);

// List available Figma resources
const resources = await client.request(
  { method: "resources/list" },
  ListResourcesResultSchema
);

// Read a specific Figma file
const fileContent = await client.request(
  {
    method: "resources/read",
    params: {
      uri: "figma:///file/key"
    }
  },
  ReadResourceResultSchema
);

// Watch for file changes
const watcher = await client.request(
  {
    method: "resources/watch",
    params: {
      uri: "figma:///file/key"
    }
  },
  WatchResourceResultSchema
);

// Handle resource updates
client.on("notification", (notification) => {
  if (notification.method === "resources/changed") {
    console.log("Resource changed:", notification.params);
  }
});

Resource URIs

The server implements a custom figma:/// URI scheme for accessing Figma resources:

Files: figma:///file/{file_key}
Components: figma:///component/{file_key}/{component_id}
Variables: figma:///variable/{file_key}/{variable_id}
Styles: figma:///style/{file_key}/{style_id}
Teams: figma:///team/{team_id}
Projects: figma:///project/{project_id}

Supported Operations

The server implements the following MCP operations:

resources/list: List available Figma resources
resources/read: Read content of Figma resources
resources/watch: Watch for resource changes
resources/search: Search across Figma resources
resources/metadata: Get metadata about resources

Debugging

Enable debug logging by setting the DEBUG environment variable:

DEBUG=figma-mcp:* npm start

Error Handling

The server implements standard MCP error codes:

-32700: Parse error
-32600: Invalid request
-32601: Method not found
-32602: Invalid parameters
-32603: Internal error
100: Resource not found
101: Resource access denied
102: Resource temporarily unavailable
