Scored across 8 tools
Disambiguation5/5
Each tool has a clearly distinct purpose with no overlap: get_earth_seasons (Earth's orbital events), get_moon_phases (lunar cycles), get_planet_events (planet rise/set times), get_planet_position (planet positional data), get_sky (complete sky summary), get_solar_eclipse_by_date (local eclipse details), get_solar_eclipses_by_year (yearly eclipse list), and get_sun_moon_data (daily sun/moon times). The descriptions reinforce these boundaries, making tool selection unambiguous.
Naming Consistency5/5
All tools follow a consistent verb_noun pattern with 'get_' prefix and snake_case: get_earth_seasons, get_moon_phases, get_planet_events, get_planet_position, get_sky, get_solar_eclipse_by_date, get_solar_eclipses_by_year, get_sun_moon_data. This predictability aids agent understanding and tool discovery.
Tool Count5/5
With 8 tools, the server is well-scoped for its celestial/astronomical domain. Each tool serves a specific, non-trivial function (e.g., planetary data, eclipse tracking, sky summaries), and none feel redundant or excessive. The count aligns with typical MCP server ranges (3-15 tools) for comprehensive coverage.
Completeness4/5
The toolset provides strong coverage for astronomical queries, including planetary positions, lunar phases, solar eclipses, and sky summaries. Minor gaps exist, such as no tool for stellar data (stars/constellations) or historical astronomical events, but core workflows (e.g., 'what's visible tonight?', eclipse planning) are well-supported without dead ends.
