What it does
MCP for Unity connects AI assistants to a running Unity Editor (2021.3 LTS to 6.x) through a Unity package and a Python server run with uv. About 50 tool entry points create scenes and GameObjects, edit C# scripts, manage assets, packages, VFX, animation and UI, run tests, profile and build, and its unity-mcp-orchestrator skill teaches the agent a resource-first workflow. One menu item in Unity configures every detected client (or install with openupm add com.coplaydev.unity-mcp). Free and MIT, maintained by Coplay (Aura); not affiliated with Unity Technologies, whose own Claude Code plugin is under the Unity Companion License.
