THE RISK

Critical Risk

Why delete_project needs a policy

Deleting a project is irreversible and will likely remove all associated tasks and data within that project. This is a destructive operation that cannot be undone, fitting the Destructive category. Severity is high because accidentally deleting a project could result in significant loss of organized work and task information. The confidence is high because the intent is explicit and unambiguous.

From the tool's definition Tool name is "delete_project" and description states "Delete a project." The word "delete" indicates irreversible removal of data.

POLICY

How to control delete_project

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

policy.json

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

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