THE RISK

Critical Risk

Why delete_task needs a policy

This tool performs an irreversible deletion operation on task data in TickTick. Deletion cannot be undone and represents permanent data loss. While not as severe as some destructive operations (no cascade delete indicated for entire projects), the tool still destroys user data. Destructive is the appropriate category, ranking above Write operations.

From the tool's definition Tool name is 'delete_task' and description states '删除任务' (delete task). The function accepts 'task_id_or_title' as input and returns a deletion operation response. This irreversibly removes task data.

POLICY

How to control delete_task

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

policy.json

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

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

Can I rate-limit delete_task? +

Yes. Add a rate_limit block to the delete_task rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block delete_task completely? +

Set action: deny in the PolicyLayer policy for delete_task. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides delete_task? +

Enforce policy on every TickTick MCP Service tool call.

Start from TickTick MCP Service, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
