{
  "mcpServers": {
    "xats": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "xats-mcp"
      ],
      "env": {
        "XATS_MCP_URL": "<XATS_MCP_URL>",

    }
  }

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
