Learn this spell

Claude Code

npm install -g unity-mcp-cli
unity-mcp-cli install-plugin ./MyUnityProject
unity-mcp-cli login
unity-mcp-cli setup-mcp claude-code ./MyUnityProject

Codex

npm install -g unity-mcp-cli
unity-mcp-cli install-plugin ./MyUnityProject
unity-mcp-cli login
unity-mcp-cli setup-mcp codex ./MyUnityProject

Notes

Needs a Unity project whose path has no spaces. After login, run unity-mcp-cli setup-mcp claude-code ./MyUnityProject, or the same command with codex. Window/AI Game Developer can configure the client instead. Sign-in uses ai-game.dev. Separate from CoplayDev/unity-mcp.
