THE RISK

Critical Risk

Why batch_remove_items needs a policy

Removing tasks or projects from OmniFocus deletes data that cannot be automatically recovered through the tool itself. 'Remove' semantics in task management systems typically mean permanent deletion. The batch operation capability increases severity by enabling large-scale data loss in a single call.

From the tool's definition Tool name 'batch_remove_items' combined with description 'Remove multiple tasks or projects from OmniFocus in a single operation' indicates irreversible deletion.

POLICY

How to control batch_remove_items

PolicyLayer is an MCP gateway — it sits between your AI agents and OmniFocus MCP Enhanced, 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 Enhanced — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
