Why delete-task needs a policy

This tool permanently removes a task from Google Tasks without the ability to undo the action. While the blast radius is limited to individual tasks rather than entire systems, the destruction is irreversible and represents a Destructive category operation.

From the tool's definition Tool name is 'delete-task' with description 'Delete a task'. The verb 'delete' indicates irreversible removal of data.

POLICY

How to control delete-task

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