 Proudly sponsored and maintained by Aura — the AI assistant for Unreal & Unity.
 Now you can automate playtesting with Autopilot, the new open-source game tester.



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 Model Context Protocol. Give your LLM the tools to manage assets, control scenes, edit scripts, run tests, and automate your game dev workflows.
