Implementation Reference

• src/index.ts:138-152 (handler)

  The handler for the 'send_control_character' tool. It extracts the 'letter' from arguments, simulates Ctrl+C on Windows using taskkill if letter is 'C', and returns a confirmation message.

  case 'send_control_character': {
    const { letter } = request.params.arguments as { letter: string };
    // On Windows, we'll use taskkill to simulate Ctrl+C
    if (letter.toUpperCase() === 'C' && os.platform() === 'win32') {
      exec('taskkill /im node.exe /f');
    }
    return {
      content: [
        {
          type: 'text',
          text: `Sent Ctrl+${letter.toUpperCase()} signal`,
        },
      ],
    };
  }
