Two tools with identical empty input schemas and minimal descriptions. Both tools have clear verb-noun naming (get_current_time, list_approved_servers) following baseline conventions. Descriptions are present but generic (194-char baseline; these are ~120-140 chars). No parameter descriptions exist (both have empty properties). No output schemas documented. Security implementation is solid (whitelist, IP blocking, rate limiting) but not reflected in tool definitions. Error handling exists in code but not surfaced to LLM via tool descriptions.

• Add output schema to get_current_time documenting returned fields: {timestamp: string (ISO 8601), timezone: string, server: string, source: string}.
• Add output schema to list_approved_servers documenting returned structure: {servers: [{name: string, region: string}], count: integer}.
• Expose NTP_SERVER and TZ as optional tool parameters with enums/defaults instead of env vars. Allow LLMs to call get_current_time(server='time.google.com', timezone='UTC') at runtime.
• Enhance get_current_time description to ~150 chars: 'Fetch current time from a trusted NTP server (default pool.ntp.org). Returns ISO 8601 timestamp and timezone. Use when system clock may be unreliable or timezone conversion is needed. Retries up to 3 times on network failure.'
• Add error classification to descriptions: 'Retryable errors: network timeout, NTP server unreachable. Non-retryable: server not in approved list, invalid timezone. On error, falls back to system time.'

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
