Delete a checklist. Use this tool to remove a checklist from a card.
AI agents call delete_checklist to permanently remove resources in Trello — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (a checklist) from a Trello card. While the blast radius is moderate (losing a checklist is less severe than deleting an entire board), the destructive nature and inability to undo the action post-API-call places it in the Destructive category. Severity is medium because it affects a single organizational element within a card, not the entire board or financial data.
From the tool's definition The tool explicitly uses the verb 'Delete' and the description states 'remove a checklist from a card.' The action is irreversible—once deleted, the checklist and its items are gone unless restored through Trello's undo feature (if available) or backups.
Documented attack patterns abuse exactly the kind of access delete_checklist gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trello, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_checklist:
{
"version": "1",
"default": "deny",
"hide": [
"delete_checklist"
]
}delete_checklist disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
