Today I tried to launch the MCP Server for Google Antigravity. everything possible is included, and I tried to somehow tweak the standard Json connection:

{
  "mcpServers": {
    "Roblox_Studio": {
      "command": "cmd.exe",
      "args": [
        "/c",
        "cd /d %LOCALAPPDATA%\\Roblox && .\\mcp.bat"
      ]
    }
  }
}

but it didn’t help. Can you provide the correct JSON file or suggest how to do it properly?

    },

    }
  }
}


This is what I use for Google Antigravity.
