memory_delete_event
AI agents call memory_delete_event to permanently remove resources in AWS IoT SiteWise MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'delete' verb in the tool name places this in the Destructive category, as deletion operations cannot be undone. While the empty description reduces confidence slightly, the explicit use of 'delete' in the name is a clear signal of destructive capability. Severity is high because unauthorized deletion of events could cause data loss and operational disruption in an AWS IoT SiteWise context.
From the tool's definition Tool name 'memory_delete_event' contains the verb 'delete', which indicates irreversible removal of data. No description provided, but the name strongly suggests permanent deletion of an event from memory or storage.
