Before you use it
Made by Coplay, who also sell a paid AI assistant for Unity. This open-source package works on its own without it.
Why it's useful
Your AI assistant can make scenes, place and change GameObjects, write and fix C# scripts, manage assets and run tests in an open Unity project, instead of you copying code back and forth. It is the most used Unity bridge of its kind.
What it needs
Unity 2021.3 LTS to Unity 6, Python 3.10+ with uv, and Claude Code, Claude Desktop, Cursor or another MCP client. Your own AI subscription or API key.
