Overview
Unity package that runs an MCP server connected to the Unity Editor, so agents such as Claude Code, Cursor, Codex and Copilot can create GameObjects, edit scenes and assets, write and run C# scripts, run tests and read console logs. It also generates agent skills for the project and can run inside a compiled game for in-game LLM use. Connects over stdio locally or HTTP remotely.
Who it is for: Unity developers who want AI coding agents to operate the Editor
Strengths
- 70+ built-in tools covering assets, scenes, components, scripts, console logs, tests and screenshots
- Works with many MCP clients: Claude, Codex, Cursor, Copilot, Gemini, Cline, Rider, VS Code
- Runs in compiled games, not only the Editor, for in-game AI and debugging
- Custom tools can be added in project C# code; extension packages exist for Terrain, Timeline and others
Weaknesses
- Unity-only; no use outside Unity projects
- Project path cannot contain spaces
- CLI quick start includes sign-in to ai-game.dev; local-only requirements unclear in the README
- Reflection and dynamic Roslyn script execution give agents broad access to the project
What it needs
- Needs Unity Editor, Node.js and npm (for unity-mcp-cli), Docker (optional, for hosting the MCP server)
- Models: Claude, Codex, Cursor, GitHub Copilot, Gemini
