The Anki tool acts as an MCP server, enabling direct interaction with the Anki flashcard system. It operates through the AnkiConnect add-on, allowing users to programmatically add various types of cards (basic and cloze), manage decks, and search for existing cards. This automation streamlines the process of populating Anki with new learning material, making it ideal for integrating with other systems like Claude Desktop or Claude Code to enhance study workflows.
