Why numbers_delete_table needs a policy

This tool permanently removes a table and its contents from a Numbers spreadsheet. The action cannot be undone programmatically through the MCP server interface, making it destructive. While the blast radius is somewhat limited to a single table rather than entire documents, deletion of data structures is categorized as Destructive per the classification rules, which ranks higher than Write or Execute.

From the tool's definition Tool name is 'numbers_delete_table' and description states 'Delete a table from a sheet'. The verb 'delete' combined with deletion of a table (structured data) indicates irreversible data removal.

POLICY

How to control numbers_delete_table

PolicyLayer is an MCP gateway — it sits between your AI agents and Iwork, and nothing reaches the server without passing your rules. This is the rule we recommend for numbers_delete_table:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "numbers_delete_table"
  ]
}

numbers_delete_table disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
