MCP Remote macOS Control Server + AI Chat Web App

The first open-source MCP server that enables AI to fully control remote macOS systems, now with a web-based chat interface.

This project provides both:

1. MCP Server - Python-based server for remote macOS control via VNC
2. AI Chat Web App - Modern web interface for chatting with AI to control your Mac

🚀 Quick Start for Web App

Prerequisites

• Docker Desktop installed
• Node.js 18+ installed
• A Mac with Screen Sharing enabled (can be the same machine)

1. Clone and Setup

git clone <repository-url>
cd mcp_macos

# Install root dependencies
npm install

# Install frontend and backend dependencies
npm run install:all

2. Configure Environment

# Copy example environment file
cp backend/.env.example backend/.env

# Edit backend/.env with your settings:
# - MACOS_HOST=localhost (for local control)
# - MACOS_PASSWORD=your_vnc_password
# - OPENAI_API_KEY=your_openai_api_key

3. Enable Screen Sharing (macOS)

1. Open System Preferences > Sharing
2. Enable "Screen Sharing"
3. Set a VNC password when prompted

4. Run the Application

# Start both frontend and backend
npm run dev

# Or start individually:
npm run dev:frontend  # Frontend on http://localhost:3000
npm run dev:backend   # Backend on http://localhost:3001

5. Open and Chat!

1. Open http://localhost:3000 in your browser
2. Wait for connection to establish
3. Try commands like:
   • "Take a screenshot"
   • "Open Safari"
   • "Click on the Dock"
   • "Type hello world"

🎯 Architecture

Browser ←→ Frontend (Next.js) ←→ Backend (Node.js) ←→ MCP Server (Python) ←→ macOS
         WebSocket/HTTP        Socket.IO/REST      Docker/stdio         VNC

🛠️ How It Works

1. Frontend: Modern React app with real-time chat interface
2. Backend: Express.js server with Socket.IO for real-time communication
3. LLM Integration: OpenAI GPT-4 for natural language understanding
4. MCP Client: Communicates with Python MCP server via Docker
5. macOS Control: VNC-based control of local or remote Macs

🎮 Example Interactions

You: "Take a screenshot"
AI: "Here's a screenshot of your Mac desktop:" [shows image]

You: "Click on Safari in the dock"
AI: "I'll click on Safari in the dock for you" [clicks Safari]

You: "Open a new tab and go to apple.com"
AI: "Opening a new tab and navigating to apple.com" [executes commands]

🔒 Security Notes

• Only use with Macs you own or have explicit permission to control
• VNC passwords are transmitted securely
• LLM API keys are stored server-side only
• All actions are logged for debugging

📚 Original MCP Server Documentation

The original Python MCP server functionality remains fully intact. See below for the original documentation about using it directly with Claude Desktop.

We welcome contributions!

Features

• No Extra API Costs: Free screen processing with your existing Claude Pro plan
• Minimal Setup: Just enable Screen Sharing on the target Mac – no additional software needed
• Universal Compatibility: Works with all macOS versions, current and future

Why We Built This

Native macOS Experience Without Compromise

The macOS native ecosystem remains unmatched in user experience today and will continue to be the gold standard for years to come. This is where human capabilities truly thrive, and now your AI can operate in this environment with the same fluency.

Open Architecture By Design

• Universal LLM Compatibility: Work with any MCP Client of your choice
• Model Flexibility: Seamlessly integrate with OpenAI, Anthropic, or any other LLM provider
• Future-Proof Integration: Designed to evolve with the MCP ecosystem

Effortless Deployment

• Zero Setup on Target Machines: No background applications or agents needed on macOS
• Screen Sharing is All You Need: Control any Mac with Screen Sharing enabled
• Eliminate Backend Complexity: Unlike other solutions that require running Python applications or background services

Streamlined Bootstrap Process

• Leverage Claude Desktop's Polished UI: No need for developer-style Python interfaces
• Intuitive User Experience: Interact with your AI-controlled Mac through a familiar, user-friendly interface
• Instant Productivity: Start working immediately without configuration hassles

Architecture

Installation

• Enable Screen Sharing on MacOs If you rent a mac from macstadium.com, you can skip this step
• Connect to your remote MacOs
• Install Docker Desktop for local Mac
• Add this MCP server to Claude Desktop You can configure Claude Desktop to use the Docker image by adding the following to your Claude configuration:

{
  "mcpServers": {
    "remote-macos-use": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "-e",
        "MACOS_USERNAME=your_macos_username",
        "-e",
        "MACOS_PASSWORD=your_macos_password",
        "-e",
        "MACOS_HOST=your_macos_hostname_or_ip",
        "--rm",
        "buryhuang/mcp-remote-macos-use:latest"
      ]
    }
  }
}

WebRTC Support via LiveKit

This server now includes WebRTC support through LiveKit integration, enabling:

• Low-latency real-time screen sharing
• Improved performance and responsiveness
• Better network efficiency compared to traditional VNC
• Automatic quality adaptation based on network conditions

To use WebRTC features, you'll need to:

1. Set up a LiveKit server or use LiveKit Cloud
2. Configure the LiveKit environment variables as shown in the configuration example above

Usage

The server provides Remote MacOs functionality through MCP tools.

Tools Specifications

The server provides the following tools for remote macOS control:

remote_macos_get_screen

Connect to a remote macOS machine and get a screenshot of the remote desktop. Uses environment variables for connection details.

remote_macos_send_keys

Limitations

• Authentication Support:
  • Only Apple Authentication (protocol 30) is supported

Security Note

https://support.apple.com/guide/remote-desktop/encrypt-network-data-apdfe8e386b/mac https://cafbit.com/post/apple_remote_desktop_quirks/

We only support protocol 30, which uses the Diffie-Hellman key agreement protocol with a 512-bit prime. This protocol is used by macOS 11 to macOS 12 when communicating with OS X 10.11 or earlier clients.

Here's the information converted to a markdown table:

macOS version running Remote Desktop	macOS client version	Authentication	Control and Observe	Copy items or install package	All other tasks	Protocol Version
macOS 13	macOS 13	2048-bit RSA host keys	2048-bit RSA host keys	2048-bit RSA host keys to authenticate, then 128-bit AES	2048-bit RSA host keys	36
macOS 13	macOS 10.12	Secure Remote Password (SRP) protocol for local only. Diffie-Hellman (DH) if bound to LDAP or macOS server is version 10.11 or earlier	SRP or DH,128-bit AES	SRP or DH to authenticate, then 128-bit AES	2048-bit RSA host keys	35
macOS 11 to macOS 12	macOS 10.12 to macOS 13	Secure Remote Password (SRP) protocol for local only, Diffie-Hellman if bound to LDAP	SRP or DH 1024-bit, 128-bit AES	2048-bit RSA host keys macOS 13 to macOS 10.13	2048-bit RSA host keys macOS 10.13 or later	33
macOS 11 to macOS 12	OS X 10.11 or earlier	DH 1024-bit	DH 1024-bit, 128-bit AES	Diffie-Hellman Key agreement protocol with a 512-bit prime	Diffie-Hellman Key agreement protocol with a 512-bit prime	30

Always use secure, authenticated connections when accessing remote remote MacOs machines. This tool should only be used with servers you trust and have permission to access.
