THE RISK

Why ticktick_delete_habit needs a policy

This tool permanently removes a habit record with no undo capability. Permanent deletion is irreversible and cannot be undone, making it a Destructive action. While the blast radius is constrained to a single habit record (not system-wide data), accidental deletion by an AI agent could cause data loss that the user cannot recover.

From the tool's definition Tool name contains 'delete' and description states 'Delete a habit permanently'. The word 'permanently' explicitly indicates irreversible data destruction.

POLICY

How to control ticktick_delete_habit

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

policy.json

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

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