gateway_resource_policy_delete
AI agents call gateway_resource_policy_delete to permanently remove resources in Amazon ElastiCache Memcached MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

This qualifies as Destructive rather than Write because the action cannot be reversed. Severity is high because deleting resource policies can break access controls and network connectivity for dependent services.
