AI agents call delete_person to permanently remove resources in Folk 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. Removing a person record from a CRM system constitutes permanent data loss. Even without a description, the verb 'delete' combined with the domain context (CRM contact management) clearly indicates a destructive operation.
From the tool's definition Tool name is 'delete_person' with empty description. The name explicitly indicates deletion of a person record from the Folk CRM system.
Documented attack patterns abuse exactly the kind of access delete_person gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Folk CRM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_person:
{
"version": "1",
"default": "deny",
"hide": [
"delete_person"
]
}delete_person disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
