Retrieve new unseen cards that haven
AI agents call get_new_cards to retrieve information from Anki MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves flashcard data from an Anki collection without modifying, deleting, or executing operations. Retrieving study cards for review scheduling is a standard read operation. Risk is minimal as it only exposes existing flashcard metadata to the AI agent.
From the tool's definition Tool name 'get_new_cards' and description 'Retrieve new unseen cards' indicates a query/retrieval operation with no side effects. The verb 'retrieve' confirms data access only.
