THE RISK

Why numbers.remove_sheet needs a policy

Removing a sheet from a spreadsheet is a destructive action that cannot be easily undone. While users may have backups, the operation permanently deletes the sheet and any data it contained from the active spreadsheet. This is an irreversible data loss operation that justifies the Destructive category.

From the tool's definition Tool name is 'numbers.remove_sheet' and description states it will 'Remove a sheet from a Numbers spreadsheet' — this irreversibly deletes a sheet and its data from a spreadsheet file.

POLICY

How to control numbers.remove_sheet

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "numbers.remove_sheet"
  ]
}

numbers.remove_sheet 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 Orchard — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
