This server has two simple read-only tools with adequate naming and descriptions, but lacks critical elements expected in production tools. Both tools have descriptions in the 20-80 character range (meeting minimum), but parameter descriptions could be stronger. The `time_now_with_timezone` tool has a well-described timezone parameter, but error handling is weak (returns error strings instead of structured failures). No output schema documentation visible. The tools are idempotent and low-risk (READ_ONLY), but the server is very narrow in scope and lacks resilience patterns.

• Document the exact output format for each tool. E.g., 'Returns: string in ISO 8601 datetime format (YYYY-MM-DDTHH:MM:SS±HH:MM) or ISO 8601 time format (HH:MM:SS).'
• Replace unstructured error strings with structured failure responses. Define an error schema and return {'error': 'unknown_timezone', 'message': 'Timezone "Invalid/Zone" not found', 'suggestions': ['America/New_York', 'Europe/London', 'UTC']}.
• Add timezone parameter constraint documentation: 'Must be a valid IANA timezone name (e.g., America/New_York, Europe/London, Asia/Tokyo, UTC). Use list_timezones() to discover valid options.'
• Clarify time_now return value in description: 'Returns the current time in HH:MM:SS ISO 8601 format (time component only, no date or timezone). For full datetime, use time_now_with_timezone().'
• Add a third tool: list_timezones() or describe_timezones() that returns available timezone options. This matches the discovery pattern and gives agents a way to resolve invalid timezone errors.
• Add per-parameter type hints in docstring if not already inferred by FastMCP framework (verify FastMCP auto-generates JSON schemas from type hints).
