List all Anki decks
AI agents call list_decks 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 performs a read-only operation—it retrieves and lists decks with no side effects or ability to modify, delete, or create data. The blast radius of misuse is minimal, as listing decks exposes only structural information about the user's Anki collection without enabling destructive or sensitive actions.
From the tool's definition Tool name 'list_decks' and description 'List all Anki decks' indicate a query operation that retrieves existing deck information without modification.
