What's Good

MIT (CoplayDev/unity-mcp), release v10.3.0 (2026-10-04). About 50 focused tool entry points grouped into toggleable sets (VFX, animation, UI, testing), Roslyn validation of generated scripts, multi-instance routing for several open editors, and an optional remote server with auth. Install is a Unity Package Manager git URL (or OpenUPM), then one menu item configures every detected client. Supports Unity 2021.3 LTS through 6.x. ★~15k.

The Catch

Needs Python 3.10+ via uv alongside Unity. An agent with editor access can make a mess of a scene or project, so keep the project in version control and review changes. Maintained and sponsored by Aura, whose paid Unity/Unreal assistant is pitched in the README; the MCP server itself is free. Not affiliated with Unity Technologies.

Verdict

The most complete free bridge between coding agents and the Unity Editor — commit before you prompt.
