Find decks by name (case-insensitive partial match). Useful when you know the deck name but not its ID.
AI agents call find_deck_by_name 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 information about flashcard decks without any side effects. It performs a case-insensitive search to help locate decks, which is a standard Read operation. There is no creation, modification, deletion, or execution of external operations. The low severity reflects the minimal risk of misuse - an agent querying deck names poses no threat to data integrity or functionality.
From the tool's definition Tool description states 'Find decks by name' with a 'partial match' - this is purely a search/query operation with no modification or deletion of data. The verb 'find' and the use case of retrieving a deck by name indicates data retrieval only.
