WHAT IT DOES

What gui_add_cards does on Anki

AI agents use gui_add_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 gui_add_cards is rated Medium

Adding cards to an Anki deck creates new data entries in the flashcard collection. This is reversible (cards can be deleted later) and does not destroy data, so it falls under Write rather than Destructive.

From the tool's definition Tool name 'gui_add_cards' indicates it adds/creates new flashcard entries in the Anki database. The 'gui_' prefix suggests it interacts with the graphical user interface to perform card creation operations.

RECOMMENDED RULE

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

gui_add_cards Rate-limited

gui_add_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.
