{
    "mcp": {
        "servers": {
            "Unity-MCP-Test": {
                "type": "stdio",
                "command": "C:/Projects/Unity/Ivan Murzak Unity Modules/Unity-MCP/Library/com.ivanmurzak.unity.mcp.server/bin~/Release/net9.0/com.ivanmurzak.unity.mcp.server.exe",
                "args": [
                ]
            }
        }
    }
}
