How to connect Unity MCP
Unity MCP runs locally from a .NET package published to NuGet: IsuzuUnityCli version 4.4.2. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs the .NET SDK; run as a .NET tool. It reads these environment variables: UNITY_MCP_STATE_DIR and UNITY_MCP_HOST; set them in the client's configuration for this server.
