Proudly sponsored and maintained by Aura — the AI assistant for Unreal & Unity.
And don't miss Godot AI, the new open source MCP/AI project from the makers of MCP for Unity.
Create your Unity apps with LLMs. MCP for Unity bridges AI assistants — Claude, Codex, VS Code, local LLMs, and more — with your Unity Editor via the Model Context Protocol. Give your LLM the tools to manage assets, control scenes, edit scripts, run tests, and automate workflows.
In Unity: Window → Package Manager → + → Add package from git URL, paste:
https://github.com/CoplayDev/unity-mcp.git?path=/MCPForUnity#main
Beta channel uses #beta. Asset Store and OpenUPM paths are documented in the Install guide.
Then Window → MCP for Unity → Configure All Detected Clients. That's it — try a prompt:
Create a red, blue, and yellow cube in the current scene.
Full walkthrough: Your First Prompt.
