One EXE. No Python. No Docker. 120 Windows automation tools written in Go.

I built a Windows computer-use MCP server in pure Go. One EXE. No Python. No Docker.

It's a single 27 MB executable that gives local LLMs (Claude, Gemini, Cursor, Kiro, OpenCode, Ollama, you name it) the ability to actually use a Windows desktop. Think of it as giving an LLM a mouse, keyboard, eyes, and long-term memory.

(Screenshots and demo clips coming soon — wanted to get the post up first.)

Over 14,000 lines of Go, zero dependencies on OpenCV, go-ole, or any COM binding library. Almost every subsystem was implemented from scratch in pure Go instead of wrapping existing libraries.

The fun part
