local-only server

The server can only run on the client’s local machine because it depends on local resources.

MCPControl

Windows control server for the Model Context Protocol, providing programmatic control over system operations including mouse, keyboard, window management, and screen capture functionality.

I developed this project as an experiment a few months ago, wanting to see if Claude could play some video games. After seeing it work, I was impressed but set it aside. Recently, it's gained attention from the community, prompting me to resume development. While currently in pre-release state, I'm actively working toward a stable version. If you encounter any issues, please submit them through the issue tracker.

Note: This project currently supports Windows only.

Development Requirements

To build this project for development, you'll need:

Windows operating system (required for the keysender dependency)
Node.js 18 or later (install using the official Windows installer which includes build tools)
npm package manager
Native build tools:
- node-gyp: npm install -g node-gyp
- cmake-js: npm install -g cmake-js

The keysender dependency relies on Windows-specific native modules that require these build tools.

MCP Server Configuration

To use this project, you'll need the necessary build tools:

Install Node.js using the official Windows installer, which includes necessary build tools
Install additional required tools:

npm install -g node-gyp
npm install -g cmake-js

Then, add the following configuration to your MCP settings:

{
  "mcpServers": {
    "MCPControl": {
      "command": "npx",
      "args": [
        "--no-cache",
        "-y",
        "mcp-control"
      ]
    }
  }
}

After configuring your MCP settings, restart your client to see the MCPControl service in the menu.
