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.
