delete_subtask

THE RISK

Critical Risk

An AI agent that decides to call delete_subtask doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from TaskFlow MCP is gone — there is no undo for destructive operations.

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

HOW TO CONTROL DELETE_SUBTASK

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

policy.json

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

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