Frequently Asked Questions

What can Unity MCP do?

Lets AI agents directly operate the Unity Editor: create and delete game objects, modify Transform components, edit materials and shaders, start/stop Play mode, execute C# scripts, and query scene hierarchy. Ideal for AI-assisted game development, scene building, and automated testing.

What do I need to install for Unity MCP?

You need Unity Editor (2019.4 or newer) and Node.js. The MCP server connects via Unity's Editor Scripting API and auto-connects to running Unity instances. It's recommended to install the companion Editor package in your Unity project.
