AI agents may call delete_attachment to permanently remove or destroy resources in ServiceNow MCP Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
