Generated Files

mcp-server.js

const { createMCPServer } = require('@supernal/interface/mcp-server');

// Import your tool providers
// const { MyTools } = require('./dist/tools/MyTools');

const server = createMCPServer({
  name: 'my-app-tools',
  version: '1.0.0',
  tools: [
    // Add your tool providers here:
    // new MyTools()
  ]
});

server.start();

console.log('MCP server started');

package.json scripts

{
  "scripts": {
    "mcp": "node mcp-server.js",
    "mcp:debug": "DEBUG=mcp:* node mcp-server.js"
  }
}

Manual Configuration Required

After running this skill, you need to manually configure your IDE:

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "my-app-tools": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-server.js"]
    }
  }
}

Cursor IDE

Edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "my-app-tools": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-server.js"]
    }
  }
}

Enterprise Tip

For automatic IDE configuration, use the enterprise CLI:

npm install @supernalintelligence/interface-enterprise
npx si setup-mcp

This automatically:

• Detects Claude Desktop and Cursor
• Updates config files with correct paths
• Tests the server connection
• Restarts IDEs if needed
