policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_bare_metal_servers_by_status": {}
  }
}

list_bare_metal_servers_by_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
