Unity-MCP

Why we included this project

Unity teams that want an AI assistant to do genuine work in their projects will find this plugin a working bridge between the editor and coding assistants like Claude, Copilot, Cursor, and Gemini. It exposes a broad set of tools that let the assistant create GameObjects, manage assets, write and edit C# scripts, and run a full develop-and-test loop inside the actual project, where it can verify the code it produces. The plugin can also run inside a compiled game, so it can drive dynamic NPC behavior and debug at runtime as well as in the editor. Setup goes through an installer, an OpenUPM package, or a CLI that auto-generates project-specific skills, and any C# method becomes a tool with a single attribute. For indie developers and small teams, this is a copilot that operates on the real Unity project rather than answering from a separate chat window.
