MCP for Unity

Présentation

Connects an AI assistant to a running Unity Editor. It exposes tools to create and edit GameObjects, components, prefabs, scenes, materials, shaders, textures, animation, physics, VFX and UI Toolkit. It can also write and validate C# scripts, read the console, run Unity Test Framework tests, manage packages and trigger player builds.

Runs locally with uvx over stdio (or optionally HTTP), and needs Python with uv. The Unity package must also be installed in your project so the Editor can connect to the server. No API key or sign-in is needed for local use. Maintained by Coplay and not affiliated with Unity Technologies.
