Our reading of Roblox, from the data

Roblox is a gaming MCP server.

We haven't measured its tool list yet, so its token cost is unknown.

It runs locally on your machine over stdio.

claude mcp add roblox-mcp-server -- npx -y roblox-mcp-server

      "args": [
        "-y",
        "roblox-mcp-server"
      ]
    }
