Permanently delete a task. Fails if the task has active children (tasks that depend on it).
AI agents call delete_task to permanently remove resources in Todos — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently deletes task data without undo capability, meeting the Destructive category definition ('irreversibly deletes or overwrites data, or actions that cannot be undone'). Severity is high rather than critical because the blast radius is scoped to individual tasks and the tool includes a safety check (fails if task has active children), reducing but not eliminating risk of data loss.
From the tool's definition Tool name explicitly states 'delete_task' and description confirms 'Permanently delete a task', indicating irreversible removal of data.
Attacks that exploit this kind of access
Permanently delete a task. Fails if the task has active children (tasks that depend on it). It is categorised as a Destructive tool in the Todos MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Todos MCP server in PolicyLayer and add a rule for delete_task: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Todos. Nothing to install.
delete_task is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_task rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_task. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_task is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
