AI agents call delete_task to permanently remove resources in Twenty CRM MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion operations are irreversible and cannot be undone without external backup or recovery mechanisms. This presents a high blast radius if an AI agent mistakenly deletes critical tasks (e.g., important customer follow-ups, contractual deadlines).
From the tool's definition Tool name is 'delete_task' with description 'Delete a task from Twenty CRM'. The verb 'delete' explicitly indicates irreversible removal of data.
Documented attack patterns abuse exactly the kind of access delete_task gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twenty CRM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_task:
{
"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.
