Delete multiple notes with stable per-item outcomes.
AI agents call delete_notes_batch 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.
Deletion operations that cannot be undone fall under the Destructive category. Batch deletion amplifies the blast radius by removing multiple items in one operation, elevating severity to high. The tool does not involve financial transactions, so Destructive takes precedence over other categories.
From the tool's definition Tool name 'delete_notes_batch' combined with description 'Delete multiple notes' indicates irreversible deletion of data. The qualifier 'stable per-item outcomes' confirms deterministic, non-recoverable removal of note records.
Attacks that exploit this kind of access

Register the Anki MCP server in PolicyLayer and add a rule for delete_notes_batch: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Anki. Nothing to install.
delete_notes_batch is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_notes_batch rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_notes_batch. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
