About unity-cli

unity-cli English | Korean Control Unity Editor from the command line. Built for AI agents, works with anything. No server to run. No config to write. No process to manage. Just type a command. Why this exists I wanted to control Unity from the terminal. The existing MCP-based integrations required Python runtimes, WebSocket relays, JSON-RPC protocol layers, config files, server processes that need to be started and stopped, tool registration ceremonies, and tens of thousands of lines of over-engineered code. All just to send a simple command to Unity. On top of that, every AI agent that wanted to use it needed its own MCP config and integration setup. The CLI doesn't care — any agent that can run a shell command can use it immediately. That felt wrong. If I can a URL, why do I need all that? So I built the opposite: a single binary that talks directly to Unity via HTTP. No server to run — the Unity package listens automatically. No config to write — it discovers Unity instances on its own. No tool registration — just call by name. No caching, no protocol layers, no ceremony. The entire CLI is 800 lines of Go (plus 300 lines of help text).
