WHAT IT DOES

What answer_cards does on Anki

AI agents use answer_cards to create or update resources in Anki, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Anki environment.

RISK

Why answer_cards is rated Medium

Based on context from sibling tools (card_reviews, add_note, etc.) and the Anki domain, 'answer_cards' most likely submits answers/reviews for flashcards, which modifies review state and scheduling data. This is a Write operation as it updates card review records. Confidence is lowered due to empty description.

From the tool's definition Tool name 'answer_cards' on an Anki flashcard MCP server; description is empty and uninformative.

RECOMMENDED RULE

The rule that runs answer_cards 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 answer_cards, this is the rule to start with:

answer_cards Rate-limited

answer_cards stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
