AI agents call list-decks to retrieve information from Anki Connect 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 and displays information about Anki decks without modifying state, executing code, or triggering side effects. It is a straightforward read operation with minimal blast radius—an AI agent misusing it could only enumerate decks, which poses low risk.
From the tool's definition Tool name is 'list-decks' and the (incomplete) description indicates it shows a list. The sibling tools include read-only operations like 'find-cards', 'find-notes', and 'model-names-and-ids', establishing a pattern of query/retrieval operations.
