Retrieve information about current playback or library
AI agents call get_music_info to retrieve information from Music MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata and status information about music playback and the user's library without any ability to modify, delete, or execute operations. It is purely informational (Read category). Severity is low because retrieving music metadata poses minimal risk - no financial impact, no destructive potential, and no code execution.
