{
  "mcpServers": {
    "addy-mcp": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "addy-mcp"
      ],
      "env": {
        "ADDY_API_KEY": "<ADDY_API_KEY>",
        "ADDY_READ_ONLY": "<ADDY_READ_ONLY>",

      }
    }
  }
}

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
