      "args": [
        "-y",
        "@j.meyer/steam-mcp-server"
      ],
      "env": {
        "STEAM_API_KEY": "<STEAM_API_KEY>",
        "MY_STEAM_ID": "<MY_STEAM_ID>",

Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
