MCP.Pizza Chef: IvanMurzak
Your assistant gets hands-on access to the Unity editor: creating and moving objects, writing and running C# scripts, reading console errors and fixing them, then playing the scene to check the result. It works with Claude, Cursor, Copilot, Gemini, VS Code and others, and the same connection can run inside a compiled game for live debugging or AI-driven characters. Setup means installing a Unity package, either from the downloadable installer or the command-line helper.

Unity-MCP FAQ
Which assistants can drive Unity this way?
Claude, Codex, Cursor, GitHub Copilot, Gemini, VS Code, Rider, Visual Studio, Cline and other tools that accept MCP connections.
Does it cost anything?
The project is free and open source, and you bring your own assistant, so there is no lock-in to a single provider.
Can I use this to build a level from a description?
Yes — describe the layout you want and the assistant places the objects in the editor while you watch.
Does it only work while the editor is open?
No — unusually, it also runs inside your compiled game, so you can debug live or let characters talk to a model.
How hard is setup?
Expect a developer-level install: add the Unity package using the downloadable installer or the command-line tool, then point your assistant at it.
Can I add my own actions?
Yes — any C# method in your project can be turned into a tool for the assistant with a single line.
