Authoritative time intelligence — current time in 597 timezones, sunrise/sunset/twilight times by location (US Naval Observatory), and moon phase calendar. Essential for scientific, agricultural, and scheduling agents.
Scored across 3 tools
Each tool targets a clearly distinct aspect: astronomical events (sunrise/sunset/moonrise/moonset), current time in any timezone, and moon phases. There is no overlap in their outputs.
All tools follow a consistent 'get_' prefix with a specific noun indicating the data returned (astronomy, current_time, moon_phases). This pattern is predictable and easy to understand.
With only 3 tools, the server is well-scoped for its purpose—covering current time, astronomical events, and moon phases. Each tool is necessary and none seem redundant.
The server covers core time and astronomy needs: current time in any timezone, daily astronomical events, and moon phase information. Minor gaps exist (e.g., historical time data or planetary positions), but the surface is reasonably complete for common queries.
