Delete an Apple Note. Defaults to dryRun=true so clients can verify the resolved note before deletion.
AI agents call notes_delete to permanently remove resources in Apple Notes MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of notes is an irreversible action that destroys data without recovery. Even with dryRun=true as default, the tool's purpose is destructive. This rates 'high' severity because a misdirected deletion could lose important user information, though the scope is limited to a single note or set of notes rather than system-wide data. Destructive takes precedence over Write in the severity hierarchy.
From the tool's definition Tool name is 'notes_delete' and description states 'Delete an Apple Note.' This is an irreversible deletion operation. The dryRun default does not change the fundamental category—the tool's capability is to permanently remove data.
