Unity MCP ✨

What is Unity MCP ✨?

Unity MCP ✨ bridges AI assistants — Claude, Codex, VS Code, local LLMs, and more — with the Unity Editor via Model Context Protocol. It gives large language models the tools to manage assets, control scenes, edit C# scripts, run tests, and automate game development workflows.

How to use Unity MCP ✨?

Requires Unity 2021.3 LTS to 6.x and Python 3.10+ (via uv). Install the Unity package from the Package Manager using the git URL or via OpenUPM, then open Window → MCP for Unity → Configure All Detected Clients. Once configured, prompt any MCP‑compatible client (e.g., "Create a cube at the origin and add a Rigidbody") and the result appears in the Editor.
