Mac Control MCP Server

This is a Model Context Protocol (MCP) server that allows controlling macOS through an AI interface. It provides tools for executing AppleScript, controlling the mouse and keyboard, and retrieving system information.

Features

• Execute arbitrary AppleScript commands
• Control mouse movement and clicks
• Simulate keyboard input
• Open applications
• Retrieve system information
• New: Control your Mac using natural language with LLM integration

Setup

1. Install dependencies:

   npm install
   

2. Run the MCP server:

   npm start
   

3. For LLM integration: Set your LLM API key and run the LLM server:

   export LLM_API_KEY=your-api-key-here
   npm run serve
   

Using the LLM Interface

We've added a web interface that allows you to control your Mac using natural language commands through an LLM. To use it:

1. Run the LLM server:

   npm run serve
   

2. Open your browser and navigate to http://localhost:3000

3. Enter natural language commands like:

   • "Open the Notes application"
   • "Type 'Hello World'"
   • "Click at position x=500, y=300"
   • "Show system information"

For more detailed instructions, see the LLM Integration Guide.

Configuration

The server can be configured through environment variables or through the Smithery configuration panel:

• ENABLE_MOUSE_CONTROL: Enable or disable mouse control functions (default: true)
• ENABLE_KEYBOARD_CONTROL: Enable or disable keyboard input functions (default: true)
• ENABLE_APPLESCRIPT: Enable or disable AppleScript execution (default: true)

Implementation Details

This MCP server follows the standard MCP protocol:

• Uses STDIO for communication (stdin/stdout)
• Expects JSON messages in a specific format
• Returns JSON responses with tool results
• Can be integrated with any LLM or AI system that supports the MCP protocol

Protocol Format

    "id": "unique-id",
    "name": "tool_name",
    "params": {
      "param1": "value1"
    }
  }
}

Output Format

    "id": "unique-id",
    "result": {
      "key": "value"
    }
  }
}

Available Tools

AppleScript Tools

• run_applescript: Execute an arbitrary AppleScript command
• open_application: Open a macOS application
• get_system_info: Get basic system information

Keyboard Control Tools

• type_text: Type text via keyboard
• key_press: Press a keyboard key with optional modifier

Mouse Control Tools

• mouse_move: Move the mouse to a position

Deployment on Smithery

This repository includes the necessary configuration files for deployment on Smithery:

• Dockerfile: Defines the container build
• smithery.yaml: Configuration for the Smithery platform

Security Considerations

Since this MCP server can control your Mac, it should be used with caution:

• Be careful about allowing arbitrary AppleScript execution in production
• Consider using configuration options to disable features you don't need
• Run in a secure environment with appropriate access controls
