Ask, and the editor does it
Scenes, GameObjects, components, materials, terrain, lighting, NavMesh, animation, builds, tests, profiling, Shader Graph and Amplify Shader Editor, multiplayer play mode scenarios: the assistant drives them through the same APIs a developer would.
The showcases speak for themselves: a neon brick breaker built from scratch in under five minutes, a medieval village with sculpted terrain and procedurally built houses, a multi-room castle verified with an FPS walkthrough.
Timelapse, 12 times faster: an assistant builds a playable village through Unity MCP.
Built for real projects
About seventy core tools are always available and the rest load on demand, so clients stay within their limits. The server finds every running editor, survives long compiles and crashes, and queues work from several agents at once.
- AI assistant to MCP server to Unity plugin to Unity Editor
- Multi-instance and multi-agent support
- Scene and game view capture so the assistant can see its work
- Optional packages detected automatically
Timelapse, 10 times faster: a multi-room castle, built and then walked through.
