Scored across 2 tools
Each tool has a clearly distinct purpose: one calculates a natal chart, the other converts a location to coordinates for input; no ambiguity.
Both tools follow the 'astrology_verb_noun' pattern consistently, making the naming predictable and clear.
Two tools is minimal for the domain of astrology; while the server may be scoped narrowly, a typical user might expect additional tools like transit or synastry calculations, making it borderline.
The server covers the essential steps for natal chart calculation (coordinates + chart), but lacks tools for interpretation, aspects analysis, or other astrological functions, leaving minor gaps.
