PERMANENTLY deletes task. Use taskId (preferred/safest) or taskName + optional listName. WARNING: Cannot be undone. Using taskName without listName may match multiple tasks.
AI agents call delete_task to permanently remove resources in ClickUp MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (tasks) with no undo capability. The warning about potential ambiguity when using taskName without listName increases the risk of accidental deletion of wrong tasks. The high confidence reflects the unambiguous destructive nature, though severity is 'high' rather than 'critical' because the blast radius is typically limited to individual task records rather than system-wide data.
From the tool's definition Tool description explicitly states: 'PERMANENTLY deletes task' and 'Cannot be undone.' The name 'delete_task' combined with the permanent deletion mechanic and irreversible nature directly matches the Destructive category definition.

PERMANENTLY deletes task. Use taskId (preferred/safest) or taskName + optional listName. WARNING: Cannot be undone. Using taskName without listName may match multiple tasks. It is categorised as a Destructive tool in the ClickUp MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the ClickUp 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 ClickUp MCP. 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 ClickUp MCP server (twofeetup/clickup-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
