delete-serverless-cache
AI agents call delete-serverless-cache 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.
The tool deletes a serverless cache, which is an irreversible action that cannot be undone. Once deleted, the cache and its data are gone. This fits the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' Even though the description is empty, the name itself provides sufficient evidence of destructive capability.
