Unity CLI MCP server by Unity Technologies
The Unity CLI includes an MCP server, started with `unity mcp` and built on the Unity Pipeline package, that lets external coding agents such as Claude Code, Cursor, VS Code and Windsurf control a running Unity Editor locally. It replaces the deprecated MCP server in the com.unity.ai.assistant package, is marked experimental, and works alongside Unity's skills-only plugin for Claude Code, Codex and Grok.
