How to control numbers_get_table_info

policy.json

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

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

Create a free account and register Iwork — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
