Get content of multiple cards (bulk)
AI agents call get_cards to retrieve information from Mochi 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 or queries card content in bulk without side effects. It performs a read-only operation on flashcard data, consistent with the Read category definition (search, list, get, fetch). The server description notes 'safety features like two-phase commits and typed confirmations' apply to creation and deletion operations, not retrieval.
From the tool's definition Tool name 'get_cards' and description 'Get content of multiple cards (bulk)' indicate a retrieval operation with no modification or deletion of data.
