batch_remove_items

THE RISK

Critical Risk

This tool permanently deletes multiple items at once without the ability to undo. The batch nature amplifies risk since a single call can destroy many tasks/projects simultaneously. While not financial, the irreversible data loss qualifies it as Destructive (more severe than Write). High severity due to potential bulk data loss; high confidence due to explicit removal language in name and description.

From the tool's definition Tool name 'batch_remove_items' and description states it will 'Remove multiple tasks or projects from OmniFocus in a single operation' - removal is irreversible deletion.

HOW TO CONTROL BATCH_REMOVE_ITEMS

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

policy.json

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

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