THE RISK

Critical Risk

Why deleteTask needs a policy

This tool permanently removes a task, which cannot be undone. This fits the Destructive category (irreversibly deletes data). Severity is high because task deletion removes data that may be important to project management and collaboration, though the impact is scoped to individual tasks rather than entire systems.

From the tool's definition Tool name is 'deleteTask' and description states 'Delete a task from Teamwork' — the verb 'delete' indicates irreversible removal of data.

Documented attack patterns abuse exactly the kind of access deleteTask gives an agent:

POLICY

How to control deleteTask

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

policy.json

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

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