Unity MCP is an AI-powered game development assistant for Editor & Runtime. Connect Claude, Cursor, & Windsurf to Unity via MCP. Automate workflows, generate code, and enable AI within your games.

Unlike other tools, this plugin works inside your compiled game, allowing for real-time AI debugging and player-AI interaction.

Get up and running in three steps:

1. Install plugin — download the .unitypackage installer or run openupm add com.ivanmurzak.unity.mcp
   > Alternative: npx unity-mcp-cli install-plugin ./MyUnityProject — see CLI documentation
2. Pick an AI agent — Claude Code, Claude Desktop, GitHub Copilot, Cursor, or any other
