WHAT IT DOES

What delete_notes does on Anki

AI agents call delete_notes to permanently remove resources in Anki, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_notes is rated Critical

The tool's name directly indicates deletion of notes from the Anki flashcard system. This is irreversible data loss—deleted notes cannot be recovered through normal operations. Even with empty description, the naming convention is clear enough to classify with high confidence.

From the tool's definition Tool name 'delete_notes' explicitly indicates irreversible deletion of data. The verb 'delete' is a canonical destructive operation. No description provided, but the function name alone is unambiguous.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_notes safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Anki, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_notes, this is the rule to start with:

delete_notes Hidden

delete_notes is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
