Browse content from a music service. WARNING: Most services (especially Sonos Radio, Spotify, Apple Music) require authentication and will return empty results or errors if not authenticated. Check authType from sonos_list_music_services first. Only
AI agents call sonos_browse_music_service to retrieve information from Sonos Ts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries music service content without modifying, executing code, deleting, or moving money. It is a pure information retrieval function that returns search or listing results. The authentication requirement is a prerequisite for operation, not a functional change to its read-only nature. Severity is low because misuse would only expose available music metadata without affecting system state or user data.
From the tool's definition Tool name contains 'browse' and description states 'Browse content from a music service' — a retrieval operation with no side effects. The warning about authentication applies to availability but does not change the nature of the operation.
