Server has 4 tools with clear verb-noun naming (ts_list_channels, ts_create_channel, ts_update_channel, ts_delete_channel). All tools have descriptions (10-50 chars) and Zod schemas with typed parameters. However, descriptions are minimal (under 50 chars), lacking context on WHEN to use each tool or what they return. Parameter descriptions exist but are terse. Output schemas are not documented, responses are inferred from code (JSON text wrapping). Error handling returns generic error messages without recovery guidance. No tool annotations (readOnlyHint, destructiveHint) despite clear risk levels (READ_ONLY, WRITE, DESTRUCTIVE). Missing pagination for list_channels despite potential for large result sets.

• Expand tool descriptions to 100-200 characters. Include WHAT the tool does, WHEN to use it (vs similar tools), and what it returns. Example: 'List all channels on the TeamSpeak server. Returns channel ID, name, topic, and hierarchy. Call this first to discover available channels before creating or updating.'
• Document output schemas explicitly. For ts_list_channels, specify: 'Returns {channels: [{cid: number, name: string, topic: string, description: string, parentCid: number | null}], total: number}'. For create/update/delete, specify success response structure.
• Add tool annotations to server.tool() calls. Use readOnlyHint: true for ts_list_channels; destructiveHint: true for ts_delete_channel; idempotentHint: true for ts_update_channel (if idempotent).
• Enhance error responses with recovery guidance. Instead of 'Error: Channel not found', return '{success: false, error: "Channel 123 not found. Call ts_list_channels to see available channels."}'
• Add pagination to ts_list_channels: accept limit (1-100, default 20) and offset parameters; return {channels: [...], total: number, hasMore: boolean}. Cap results at 50 to prevent context window exhaustion.
