AI agents call expunge_note to permanently remove resources in Evernote MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool meets the Destructive category definition as it irreversibly deletes data (a note) and the action cannot be undone. The permanent nature of the deletion and its irreversible effect classify it as more severe than Write (which is reversible). High severity reflects the blast radius: an AI agent with misuse could permanently erase user notes, causing data loss.
From the tool's definition "Permanently delete a note" - the tool irreversibly removes data from Evernote without possibility of recovery.

"expunge_note"
]
}expunge_note disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
