设计系统MCP服务器

Design System UX MCP Server

A Model Context Protocol (MCP) server for Design System UX components and utilities. This server provides resources and tools for working with design system components, enabling AI assistants and other MCP clients to interact with design system functionality.

Features

• 🚀 MCP Server - Full Model Context Protocol implementation
• 📦 Resource Management - Dynamic resource templates for extensible functionality
• 🔌 HTTP Transport - Express-based HTTP server for MCP communication
• 🎨 Design System Integration - Ready for Next.js design system component integration
• 🎨 Figma Integration - Tools to interact with Figma files via REST API
• 📝 TypeScript - Fully typed with TypeScript
• ⚙️ Configurable - Environment-based configuration support

Installation

# Clone the repository
git clone https://github.com/kettilvo/ds-mcp.git
cd ds-mcp

Available Tools

Figma Tools

The server includes four Figma tools for interacting with Figma files:

1. figma_get_file - Retrieve a complete Figma file by file ID
2. figma_get_file_info - Get parsed information about a Figma file
3. figma_get_nodes - Retrieve specific nodes from a Figma file
4. figma_get_images - Get image URLs for exporting design assets

Setup:

1. Get a Figma Personal Access Token from Figma Account Settings
2. Set the FIGMA_ACCESS_TOKEN environment variable:
   复制

   export FIGMA_ACCESS_TOKEN="your-token-here"
   

For detailed documentation, see FIGMA_INTEGRATION.md.

Scripts

Configuration

The server can be configured using environment variables:

• PORT - Server port (default: 3000)

Configuration files are available in the config/ directory for different environments:

• local-common-config-properties - Local development
• qa-common-config-properties - QA environment
• prod-common-config-properties - Production environment

API Endpoint

The MCP server exposes a single HTTP endpoint:

POST /mcp

Handles MCP protocol requests.

Request Body:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "resources/read",
  "params": {
    "uri": "add://5/3"
  }
}

Response:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "contents": [
      {
        "uri": "add://5/3",
        "text": "{\"result\":8}"
      }
    ]
  }
}

Development

Adding New Resources

To add a new resource, use the server.registerResource() method in src/server.ts:

server.registerResource(
  'resource-name',
  new ResourceTemplate('resource://{param}', { list: undefined }),
  {
    title: 'Resource Title',
    description: 'Resource description'
  },
  async (uri, { param }) => ({
    contents: [
      {
        uri: uri.href,
        text: `Resource content for ${param}`
      }
    ]
  })
);
