THE RISK

Critical Risk

Why delete_task needs a policy

This tool permanently removes tasks from the task management system. While the scope is limited to individual tasks (not bulk deletion or the entire system), deletion is irreversible and constitutes data loss. The high severity reflects that an AI agent misusing this could systematically remove important tasks from workflows, disrupting task queues and losing task metadata.

From the tool's definition Tool name is 'delete_task' and description states 'Delete a specific task from a request.' The verb 'delete' combined with the action of removing a task irreversibly from a queue-based system indicates data destruction.

POLICY

How to control delete_task

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Taskmanager, 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 Mcp Taskmanager — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
