policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_all_tools": {}
  }
}

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

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