About this MCP

The recommended path for agent-driven Unity development. Community-maintained (CoplayDev), MIT licensed, and works with any MCP client — no Unity subscription required. **Architecture:** a Python MCP server (launched via uvx) speaks streamable-HTTP to clients and WebSocket to a Unity editor plugin. **Setup:** install the package via git URL in Unity Package Manager, then Window → MCP for Unity → Auto-Setup. Requires uv, Python 3.10+, and git-lfs. **Pair with the Unity MCP Pipeline skill** for tool-call conventions, gotchas, and verification checklists.
