Why we included this project

Game developers who already lean on AI coding assistants know the frustration of hitting a wall the moment the work moves into the Unity Editor itself. This plugin changes that by exposing the editor as Model Context Protocol tools that agents such as Claude Code, Cursor, Codex, or Windsurf can call directly. Instead of manually dragging GameObjects around or patching prefabs by hand, the assistant can query the scene hierarchy, create and load scenes, add components like Rigidbody with values already set, install packages through the Package Manager, run the Test Runner, and read console logs. That range covers the repetitive glue work of everyday editor sessions, from selecting objects in the hierarchy to creating prefabs from MonoBehaviour scripts. For solo developers and small teams shipping Unity games, it turns an LLM into an active collaborator inside the engine rather than a code generator working on the side.
