Returns a given number (num) of new and unseen cards.
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 queries and retrieves card data from the Anki deck without creating, modifying, deleting, or executing any operations. It is a pure read operation that fetches existing flashcards based on specified criteria. The blast radius of misuse is minimal—an agent could only retrieve more cards than intended, which has no destructive or financial impact.
From the tool's definition Tool name 'get_new_cards' and description 'Returns a given number (num) of new and unseen cards' indicate a retrieval operation with no modification or side effects.

"tools": {
"get_new_cards": {}
}
