MCP Unity, by CoderGamester, links AI clients to the Unity Editor through two pieces: a Unity package installed from its Git URL, which starts a WebSocket server inside the Editor on port 8090 by default, and a Node.js MCP server that the client launches locally and that forwards requests to that socket.
What it does
MCP Unity, by CoderGamester, links AI clients to the Unity Editor through two pieces: a Unity package installed from its Git URL, which starts a WebSocket server inside the Editor on port 8090 by default, and a Node.js MCP server that the client launches locally and that forwards requests to that socket. Its tools select, create, move and delete GameObjects, update components, create prefabs, scenes and materials, add packages, run Test Runner tests, read console logs, recompile scripts and control Play Mode. It also exposes resources such as the scene hierarchy, menu items and asset lists. It needs Unity 6 or later and Node.js 18, and its Editor window can write configuration for several clients.
