This server has significant definition quality gaps. Tool names follow verb_noun convention (good), but descriptions are inconsistent, some are adequate (50-80 chars) while others lack detail. Critical issue: input schemas are visible for only 2 of 11 tools (get_song_lyrics, search_songs). The remaining 9 tools declare empty input objects {} with no parameter documentation. No output schemas are documented anywhere. Error handling is minimal, tools return generic error strings without recovery guidance. No tool annotations (readOnlyHint/destructiveHint) despite clear risk classifications. Parameter descriptions are absent for most tools. The server lacks pagination support, result limits, and structured output documentation.

• Add explicit input schemas to all 9 tools with empty inputs. For example, play_song should document song_id as a required string parameter with format constraints (1-20 digits).
• Document output schemas for all tools. Example: create_listen_together_session should return {roomId: string, inviteUrl: string, expiresAt: ISO8601}.
• Add tool annotations to WRITE tools: mark create_listen_together_session, play_song, pause_playback, resume_playback, next_song, previous_song with destructiveHint=true.
• Implement structured error responses with error codes and recovery hints. Example: {error: 'NETEASE_NOT_RUNNING', message: 'NetEase Music is not running.', recovery: 'Start NetEase Music and try again.', retryable: true}.
• Add pagination to search_songs: accept offset/limit, return total_count and next_offset in response. Cap default limit at 20 and max at 100.
