Figma MCP Server: Universal Data Source Adapter for AI Applications

Overview: What is the Figma MCP Server?

The Figma MCP (Model Context Protocol) Server is a powerful tool designed to seamlessly integrate with various AI applications, such as Claude Desktop, Continue, and Cursor, by providing a standardized interface to analyze and access Figma file structures. By leveraging Model Context Protocol, this server enables AI applications to connect directly to specific data sources, enhancing their capabilities in parsing complex visual designs.

🔧 Core Features & MCP Capabilities

The Figma MCP Server offers robust features that cater to both developers and AI users. It supports the Model Context Protocol, enabling direct communication with AI clients like Claude Desktop, Continue, and Cursor. This protocol ensures a standardized interaction method, reducing integration complexity while maintaining high data fidelity.

API Endpoints & Data Extraction

• Health Check: The server provides a GET /health endpoint to ensure seamless operations and system health monitoring.
• OpenAPI Specification: A GET /openapi.json endpoint is available for integrating with existing development frameworks and tools that support OpenAPI specifications.
• MCP Manifest Download: Users can access the GET /mcp.json endpoint to download a manifest file, which contains detailed information on supported operations and data structures.
• File Analysis: The most critical endpoint is the POST /analyze, which allows users to analyze Figma files using configurable node tree depths.

Client Interaction & Command-Line Interface

The server can be used directly through both REST API calls and a command-line interface, making it flexible for various deployment scenarios. Users can start the server with either:

• A command like figma-mcp-server --cli, which opens an MCP protocol interface.
• An alternative method for those running from source: npm run start -- --cli.

Example Client Interaction

Real-world integration is simplified using a client example script. For instance, to use it, you can invoke the following command:

node client-example.js https://www.figma.com/file/FILE_ID/PROJECT_NAME?node-id=NODE_ID 2

Here, https://www.figma.com/file/FILE_ID/PROJECT_NAME?node-id=NODE_ID represents the Figma project URL and node ID, while 2 is a configurable depth parameter.

⚙️ MCP Architecture & Protocol Implementation

The Figma MCP Server architecture ensures seamless interaction between AI clients using the Model Context Protocol. The server's implementation details include:

Protocol Flow Diagram

Model Context Protocol (MCP) operates in a client-server model, where an AI application acts as the client and communicates with a local or remote server. Below is a visual representation of this protocol flow:

Data Architecture

The server's data architecture is designed to efficiently handle Figma file structures. It includes:

• Node Extraction: The POST /analyze endpoint extracts and processes Figma node hierarchies.
• Configurable Depth: Users can customize the exploration depth of nodes, ensuring detailed analysis or summarization as required.

🚀 Getting Started with Installation

Node.js Installation

To install and configure the server, follow these steps:

1. Global Installation from npm:

   npm install -g figma-mcp-server
   

2. Source Code Installation:

   git clone https://github.com/yourusername/mcp-figma.git
   cd mcp-figma
   npm install
   npm run build
   

3. Configuration: Copy the example environment file and add your Figma API key:

   cp .env.example .env
   

   Then, edit the .env file to include:

   FIGMA_API_KEY=your_figma_api_key_here
   

4. Retrieve a Figma API key from your Figma account settings: https://www.figma.com/developers/api#access-tokens

Usage Examples

As an API Server:

Start the server with:

npm start

This will launch an Express server, typically on port 3000.

Client Example Usage:

node client-example.js https://www.figma.com/file/FILE_ID/PROJECT_NAME?node-id=NODE_ID 2

The final parameter is the optional depth for node tree analysis.

💡 Key Use Cases in AI Workflows

Use Case 1: Design Analysis for AI-Assisted Design Recommendations

AI applications can use this server to extract and analyze Figma designs, providing recommendations based on design principles and best practices. For example, given a file URL and specified depth:

curl -X POST http://localhost:3000/analyze \
  -H "Content-Type: application/json" \
  -d '{"figmaUrl": "https://www.figma.com/file/FILE_ID/PROJECT_NAME?node-id=NODE_ID", "depth": 2}'

Use Case 2: Data Extraction for AI-Driven Content Generation

The Figma MCP Server can be used to extract content-rich designs, which are then fed into natural language processing modules. This enables the creation of detailed and contextually rich content that aligns with the visual design.
