List all playlists from the user
AI agents call get_user_playlists to retrieve information from Apple Music 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 queries user playlist metadata without modifying, deleting, or executing any operations. It is a read-only action that returns existing data. The low severity reflects minimal blast radius: exposure would allow an agent to see what playlists a user has, but cannot modify content, delete data, or trigger external operations.
From the tool's definition Tool name is 'get_user_playlists' and description states 'List all playlists from the user' — a pure retrieval operation with no side effects.
