Why delete-checklist-item needs a policy

This tool irreversibly deletes data (a checklist item/subtask) and cannot be undone. While the impact is scoped to a single subtask rather than an entire task list, deletion is inherently destructive. Severity is medium rather than high because the blast radius is limited to one subtask within a task, not critical business data or the entire task structure.

From the tool's definition Tool name 'delete-checklist-item' and description explicitly states 'Delete a checklist item' and 'removes just the specific subtask'. The verb 'Delete' combined with 'removes' indicates irreversible deletion of data.

POLICY

How to control delete-checklist-item

PolicyLayer is an MCP gateway — it sits between your AI agents and Microsoft Todo MCP Service, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-checklist-item:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete-checklist-item"
  ]
}

delete-checklist-item 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 Microsoft Todo MCP Service — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
