19 tools with basic schemas and descriptions, but significant gaps in parameter documentation and error handling. Most tools have 1-7 parameters with type info, but many lack descriptions or have generic ones. No tool annotations (readOnlyHint/destructiveHint). Output schemas not documented. Error recovery guidance absent. Naming is verb-first and clear (get_*, create_*, delete_*), which is good. However, descriptions average ~60 chars (below 194-char baseline) and lack context on when to use each tool or what happens on failure. No evidence of pagination, result limits, or structured output shaping.

• Add tool annotations: mark all read-only tools with readOnlyHint=true, destructive tools (delete_*) with destructiveHint=true, and idempotent tools with idempotentHint=true. This enables LLMs to reason about safety and retry logic.
• Document output schemas for all tools. For get_metrics_json, specify: {metrics: {type: object, fields: [...]}, timestamp: string}. For login, specify: {token: string, user_id: string, expires_at: string}.
• Expand descriptions to 100-200 chars. Example: 'Retrieves server statistical charts data. Call this to visualize DNS query patterns over time. Requires a valid stats_type (hour/day/month) and optional date range. Returns arrays of data points suitable for graphing.'
• Add error recovery hints. Example for delete_all_stats: 'Deletes all statistics from the server. This is irreversible. If called without confirmation, return an error asking the user to confirm via a separate confirm_delete_stats tool.'
• Implement confirmation pattern for destructive operations: add a confirm_delete_all_stats(confirmation_token) tool that requires a token from delete_all_stats to complete the deletion. This prevents accidental data loss.
