delete_comment

THE RISK

Critical Risk

Deleting comments is a destructive action that cannot be undone. While the blast radius is limited to a single comment rather than bulk data, the irreversible nature and potential to remove important collaborative context or evidence from discussions makes this a Destructive operation.

From the tool's definition Tool name is 'delete_comment' and description states 'Delete a comment from ClickUp' — the verb 'delete' explicitly indicates irreversible removal of data.

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

HOW TO CONTROL DELETE_COMMENT

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

policy.json

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

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