Each tool has a clearly distinct purpose: getBaziDetail retrieves birth chart information, getChineseCalendar provides almanac data, and getSolarTimes converts birth charts to solar times. There is no overlap in functionality, making tool selection unambiguous.

The naming follows a consistent 'get' prefix pattern (getBaziDetail, getChineseCalendar, getSolarTimes), but uses camelCase instead of snake_case. While internally consistent, the deviation from a more common verb_noun pattern is a minor flaw.

With 3 tools, the count is reasonable for a Chinese astrology/calendar server, but it feels slightly thin. A few additional tools, such as for date conversion or more detailed analyses, could enhance coverage without being excessive.

The tools cover core functions like birth chart retrieval, almanac lookup, and time conversion, but there are notable gaps. For example, there is no tool for updating or manipulating data, and advanced features like compatibility analysis or historical date lookups are missing, limiting workflow completeness.
