MCPControl

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

Note: This project currently supports Windows only.

🔥 Why MCPControl?

MCPControl bridges the gap between AI models and your desktop, enabling secure, programmatic control of:

• 🖱️ Mouse movements and clicks
• ⌨️ Keyboard input and shortcuts
• 🪟 Window management
• 📸 Screen capture and analysis
• 📋 Clipboard operations

🔌 Quick Start

Prerequisites

1. Install Build Tools (including VC++ workload)

   # Run as Administrator - may take a few minutes to complete
   winget install Microsoft.VisualStudio.2022.BuildTools --override "--wait --passive --add Microsoft.VisualStudio.Workload.VCTools --includeRecommended"
   

2. Install Python (if not already installed)

   # Install Python (required for node-gyp)
   winget install Python.Python.3.12
   

3. Install Node.js

   # Install latest LTS version
   winget install OpenJS.NodeJS
   

Installation

1. Install MCPControl Package

   npm install -g mcp-control
   

Configuration

MCPControl works best in a virtual machine at 1280x720 resolution for optimal click accuracy.

Configure your Claude client to use the SSE transport:

{
  "mcpServers": {
    "MCPControl": {
      "command": "mcp-control",
      "args": [
        "--transport",
        "sse"
      ]
    }
  }
}

Launch Server Manually (Optional)

You can also run the server directly with SSE:

mcp-control --transport sse

Restart your client and MCPControl will appear in your MCP menu!

🔧 CLI Options

MCPControl supports several command-line flags for advanced configurations:

# Run with SSE transport on default port (3232)
mcp-control --sse

# Run with SSE on custom port
mcp-control --sse --port 3000

# Run with HTTPS/TLS (required for production deployments)
mcp-control --sse --https --cert /path/to/cert.pem --key /path/to/key.pem

# Run with HTTPS on custom port
mcp-control --sse --https --port 8443 --cert /path/to/cert.pem --key /path/to/key.pem

Command Line Arguments

• --sse - Enable SSE (Server-Sent Events) transport for network access
• --port [number] - Specify custom port (default: 3232)
• --https - Enable HTTPS/TLS (required for remote deployments per MCP spec)
• --cert [path] - Path to TLS certificate file (required with --https)
• --key [path] - Path to TLS private key file (required with --https)

Security Note

According to the MCP specification, HTTPS is mandatory for all HTTP-based transports in production environments. When deploying MCPControl for remote access, always use the --https flag with valid TLS certificates.

🚀 Popular Use Cases

Assisted Automation

• Application Testing: Delegate repetitive UI testing to Claude, allowing AI to navigate through applications and report issues

• UI Testing Framework: Create robust testing scenarios with visual validation
• Demo Creation: Automate the creation of product demonstrations

⚠️ IMPORTANT DISCLAIMER

THIS SOFTWARE IS EXPERIMENTAL AND POTENTIALLY DANGEROUS

By using this software, you acknowledge and accept that:

• Giving AI models direct control over your computer through this tool is inherently risky
• This software can control your mouse, keyboard, and other system functions which could potentially cause unintended consequences
• You are using this software entirely at your own risk
• The creators and contributors of this project accept NO responsibility for any damage, data loss, or other consequences that may arise from using this software
• This tool should only be used in controlled environments with appropriate safety measures in place

USE AT YOUR OWN RISK

Development Requirements

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

1. Windows operating system (required for the keysender dependency)
2. Node.js 18 or later (install using the official Windows installer which includes build tools)
3. npm package manager
4. 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.

📋 Project Structure

• /src
  • /handlers - Request handlers and tool management
  • /tools - Core functionality implementations
  • /types - TypeScript type definitions
  • index.ts - Main application entry point

🔖 Repository Branches

• main - Main development branch with the latest features and changes
• release - Stable release branch that mirrors the latest stable tag (currently v0.2.0)

Version Installation

You can install specific versions of MCPControl using npm:

# Install the latest stable release (from release branch)
npm install mcp-control

# Install a specific version
npm install mcp-control@0.1.22

📚 Dependencies

• @modelcontextprotocol/sdk - MCP SDK for protocol implementation
• keysender - Windows-only UI automation library
• clipboardy - Clipboard handling
• sharp - Image processing
• uuid - UUID generation

🚧 Known Limitations

• Window minimize/restore operations are currently unsupported
• Multiple screen functions may not work as expected, depending on setup
• The get_screenshot utility does not work with the VS Code Extension Cline. See GitHub issue #1865
• Some operations may require elevated permissions depending on the target application
• Only Windows is supported
• MCPControl works best at 1280x720 resolution, single screen. Click accuracy is optimized for this resolution. We're working on an offset/scaling bug and looking for testers or help creating testing tools
