    A dictionary containing the user's playlists sorted by last updated date

Implementation Reference

• mcp_server/server.py:390-451 (handler)

  Primary MCP tool handler and registration for get_user_playlists. This @mcp.tool()-decorated function implements the tool logic by checking authentication status and proxying the GET request to the Tidal Flask API endpoint /api/playlists to retrieve the user's playlists.

  Core backend implementation of get_user_playlists logic in the Flask route /api/playlists (GET). Fetches playlists using session.user.playlists(), formats playlist data with details like ID, title, description, track count, and URL, sorts by last_updated descending, and returns JSON.
