Music MCP has 6 tools with explicit schemas and descriptions, but quality is inconsistent. Tool names lack clear action verbs (e.g., 'info' instead of 'get_server_info'), and several descriptions are generic or incomplete. Parameter descriptions exist but lack detail on constraints, formats, and dependencies. Output schemas are not documented. Error handling returns JSON but lacks recovery guidance. No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels. Composition is reasonable but some tools combine multiple concerns (execute_music_command handles play, pause, volume, shuffle, repeat, rating in one tool).

• Rename 'info' to 'get_server_info' and expand description to explain what diagnostic data is returned (version, capabilities, connected music service).
• Split execute_music_command into 6 focused tools: play_track, pause_playback, set_volume, set_shuffle_mode, set_repeat_mode, rate_track. Each should have a single required parameter and clear output.
• Document output schemas for all tools in tool definitions. E.g., search_music should return {results: [{track_id, title, artist, album, duration_ms}], total_count, limit}.
• Add tool annotations: mark execute_music_command, manage_playlist, queue_music with destructiveHint=true; mark get_music_info, search_music with readOnlyHint=true.
• Enhance parameter descriptions with constraint details: 'volume (0-100, default 50)', 'limit (1-100, default 20)', and document mutual exclusivity: 'Either playlistName or trackId required for add_track action'.
