[Notifications] Delete a notification.
AI agents call notifications_delete to permanently remove resources in CyPerf MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes notification records with no ability to undo the operation. While the blast radius is limited to notification data (not critical infrastructure or financial systems), the irreversibility and lack of recovery options place this in the Destructive category.
From the tool's definition Tool name 'notifications_delete' and description 'Delete a notification' indicate irreversible deletion of data.
