Retrieve cards that were failed (lapsed) within a recent number of days.
AI agents call get_lapsed_cards to retrieve information from Anki MCP Data Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and retrieves data about lapsed cards from the Anki database. The verb 'Retrieve' and the absence of any modification, deletion, or execution capability confirm this is a Read operation. There is no destructive capability, no code execution, and no data mutation. The low severity reflects minimal risk if misused by an AI agent—it can only surface existing study data without changing state.
From the tool's definition Tool name 'get_lapsed_cards' and description 'Retrieve cards that were failed (lapsed) within a recent number of days' indicate a retrieval/query operation with no side effects.
