What it does

MCP for Unity is a community project from CoplayDev that lets an MCP client drive the Unity Editor. It has two parts: a C# package added to the Unity project through the Package Manager, which runs inside the Editor, and a Python server, run with uv, that the client talks to over stdio or HTTP and that relays commands to the Editor package over a WebSocket. Through its tools an agent can build scenes and GameObjects, edit C# scripts, manage assets, run tests, profile and make builds. It supports Unity 2021.3 LTS through 6.x, can set up detected clients from an Editor window, and states that it is not affiliated with Unity Technologies.
