01 · Install Data Link

before you install - you'll need

Set DATALINK_ANALYTICS_URL, DATALINK_ANALYTICS_READONLY, DATALINK_INVENTORY_URL, DATALINK_CACHE_URL, DATALINK_MAIN_URL before connecting.

Claude Code

claude mcp add pilat-mcp-datalink -- npx -y @pilat/mcp-datalink

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pilat-mcp-datalink": {
      "command": "npx",
      "args": [
        "-y",
        "@pilat/mcp-datalink"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
