MCP Windows Desktop Automation

What is MCP Windows Desktop Automation?

MCP Windows Desktop Automation is a TypeScript server that wraps AutoIt functions via the node-autoit-koffi package, exposing them as Model Context Protocol tools, resources, and prompts. It enables LLM applications to automate Windows desktop tasks—like mouse clicks, keystrokes, window management, and screenshot capture—through a standard MCP interface.

How to use MCP Windows Desktop Automation?

Clone the repository, run npm install and npm run build, then start the server with npm start (defaults to stdio transport). For WebSocket transport, use npm start -- --transport=websocket --port=3000. Additional flags include --verbose and --port=<number>.

Key features of MCP Windows Desktop Automation

• Full wrapping of all AutoIt functions as MCP tools
• Supports both stdio and WebSocket transports
• File access resources (read files, list directories)
• Screenshot resources (capture screen or specific windows)
• Prompt templates for common automation tasks
• Strict TypeScript typing throughout

Use cases of MCP Windows Desktop Automation

• Automate form filling in legacy Windows applications
• Interact with UI controls (buttons, text fields, etc.)

FAQ from MCP Windows Desktop Automation

What does it do vs alternatives?

It wraps all AutoIt functions as MCP tools, allowing any MCP-compatible LLM app to drive Windows desktop automation without writing AutoIt scripts directly.

What are the runtime requirements?

You need Node.js (for building and running the TypeScript server) and a Windows OS with AutoIt installed via the node-autoit-koffi package.

Where does data live?

All operations happen locally on the Windows machine. File and screenshot resources read from the local filesystem; no external servers are required.

What transport options are available?

The server supports stdio (default) and WebSocket transports. WebSocket mode requires a port number (default: 3000) and is set via --transport=websocket.

Are there any known limits?

The server is a TypeScript wrapper around node-autoit-koffi; any limitations of that underlying binding (e.g., AutoIt version compatibility, 32-bit vs 64-bit) apply here as well.
