Integration Options

Cursor IDE Setup (Recommended)

The project includes pre-configured settings in .cursor/mcp.json. Simply restart Cursor IDE after installation.

Claude Desktop Configuration

Add to your Claude Desktop config:

{
  "mcpServers": {
    "coinbase-mcp": {
      "command": "node",
      "args": ["/path/to/coinbase-chat-mcp/mcp-server/dist/index.js"]
    }
  }
}

Technical Architecture

The system comprises three main components:

1. MCP Server: Core protocol implementation with 8 cryptocurrency tools
2. API Server: Express.js REST interface
3. Frontend: React application with TailwindCSS
