This is where human capabilities truly thrive, and now your AI can operate in this environment with the same fluency. 38 | 39 | ### Open Architecture By Design 40 | * **Universal LLM Compatibility**: Work with any MCP Client of your choice 41 | * **Model Flexibility**: Seamlessly integrate with OpenAI, Anthropic, or any other LLM provider 42 | * **Future-Proof Integration**: Designed to evolve with the MCP ecosystem 43 | 44 | ### Effortless Deployment 45 | * **Zero Setup on Target Machines**: No background applications or agents needed on macOS 46 | * **Screen Sharing is All You Need**: Control any Mac with Screen Sharing enabled 47 | * **Eliminate Backend Complexity**: Unlike other solutions that require running Python applications or background services 48 | 49 | ### Streamlined Bootstrap Process 50 | * **Leverage Claude Desktop's Polished UI**: No need for developer-style Python interfaces 51 | * **Intuitive User Experience**: Interact with your AI-controlled Mac through a familiar, user-friendly interface 52 | * **Instant Productivity**: Start working immediately without configuration hassles 53 | 54 | ## Architecture 55 | remote_macos_use_system_architecture 56 | 57 | 58 | ## Installation 59 | - [Enable Screen Sharing on MacOs](https://support.apple.com/guide/remote-desktop/set-up-a-computer-running-vnc-software-apdbed09830/mac) **If you rent a mac from macstadium.com, you can skip this step** 60 | - [Connect to your remote MacOs](https://support.apple.com/guide/mac-help/share-the-screen-of-another-mac-mh14066/mac) 61 | - [Install Docker Desktop for local Mac](https://docs.docker.com/desktop/setup/install/mac-install/) 62 | - [Add this MCP server to Claude Desktop](https://modelcontextprotocol.io/quickstart/user) 63 | You can configure Claude Desktop to use the Docker image by adding the following to your Claude configuration: 64 | ```json 65 | { 66 | "mcpServers": { 67 | "remote-macos-use": { 68 | "command": "docker", 69 | "args": [ 70 | "run", 71 | "-i", 72 | "-e", 73 | "MACOS_USERNAME=your_macos_username", 74 | "-e", 75 | "MACOS_PASSWORD=your_macos_password", 76 | "-e", 77 | "MACOS_HOST=your_macos_hostname_or_ip", 78 | "--rm", 79 | "buryhuang/mcp-remote-macos-use:latest" 80 | ] 81 | } 82 | } 83 | } 84 | ``` 85 | 86 | ### WebRTC Support via LiveKit 87 | 88 | This server now includes WebRTC support through LiveKit integration, enabling: 89 | - Low-latency real-time screen sharing 90 | - Improved performance and responsiveness 91 | - Better network efficiency compared to traditional VNC 92 | - Automatic quality adaptation based on network conditions 93 | 94 | To use WebRTC features, you'll need to: 95 | 1. Set up a LiveKit server or use LiveKit Cloud 96 | 2. Configure the LiveKit environment variables as shown in the configuration example above 97 | 98 | ## Developer Instruction 99 | ### Clone the repo 100 | ```bash 101 | # Clone the repository 102 | git clone https://github.com/yourusername/mcp-remote-macos-use.git 103 | cd mcp-remote-macos-use 104 | ``` 105 | 106 | ### Building the Docker Image 107 | 108 | ```bash 109 | # Build the Docker image 110 | docker build -t mcp-remote-macos-use . 111 | ``` 112 | 113 | ## Cross-Platform Publishing 114 | 115 | To publish the Docker image for multiple platforms, you can use the `docker buildx` command. Follow these steps: 116 | 117 | 1. **Create a new builder instance** (if you haven't already): 118 | ```bash 119 | docker buildx create --use 120 | ``` 121 | 122 | 2. **Build and push the image for multiple platforms**: 123 | ```bash 124 | docker buildx build --platform linux/amd64,linux/arm64 -t buryhuang/mcp-remote-macos-use:latest --push . 125 | ``` 126 | 127 | 3. **Verify the image is available for the specified platforms**: 128 | ```bash 129 | docker buildx imagetools inspect buryhuang/mcp-remote-macos-use:latest 130 | ``` 131 | 132 | ## Usage 133 | 134 | The server provides Remote MacOs functionality through MCP tools. 135 | 136 | ### Tools Specifications 137 | 138 | The server provides the following tools for remote macOS control: 139 | 140 | #### remote_macos_get_screen 141 | Connect to a remote macOS machine and get a screenshot of the remote desktop. Uses environment variables for connection details. 142 | 143 | #### remote_macos_send_keys 144 | Send keyboard input to a remote macOS machine. Uses environment variables for connection details. 145 | 146 | #### remote_macos_mouse_move 147 | Move the mouse cursor to specified coordinates on a remote macOS machine, with automatic coordinate scaling. Uses environment variables for connection details. 148 | 149 | #### remote_macos_mouse_click 150 | Perform a mouse click at specified coordinates on a remote macOS machine, with automatic coordinate scaling. Uses environment variables for connection details. 151 | 152 | #### remote_macos_mouse_double_click 153 | Perform a mouse double-click at specified coordinates on a remote macOS machine, with automatic coordinate scaling. Uses environment variables for connection details. 154 | 155 | #### remote_macos_mouse_scroll 156 | Perform a mouse scroll at specified coordinates on a remote macOS machine, with automatic coordinate scaling.

This protocol is used by macOS 11 to macOS 12 when communicating with OS X 10.11 or earlier clients. 177 | 178 | Here's the information converted to a markdown table: 179 | 180 | | macOS version running Remote Desktop | macOS client version | Authentication | Control and Observe | Copy items or install package | All other tasks | Protocol Version | 181 | |--------------------------------------|----------------------|----------------|---------------------|-------------------------------|----------------|----------------| 182 | | 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 | 183 | | 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 | 184 | | 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 | 185 | | 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 | 186 | 187 | 188 | Always use secure, authenticated connections when accessing remote remote MacOs machines.
