delete_subtask

THE RISK

Critical Risk

The tool performs an irreversible deletion of a subtask with no undo capability. This matches the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While the blast radius is constrained to a single subtask (not critical in scope), the irreversible nature and explicit warning elevate severity to high.

From the tool's definition Tool name is 'delete_subtask' and description explicitly states 'This action cannot be undone.' The delete operation irreversibly removes subtask data.

HOW TO CONTROL DELETE_SUBTASK

PolicyLayer is an MCP gateway — it sits between your AI agents and Agentic Tools MCP Server, 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
