Scored across 4 tools
Each tool has a distinct primary purpose: checking a date, adding business days, counting between dates, and calculating deadlines. There is some overlap between jp_add_business_days with negative days and jp_calc_deadline, but the descriptions clearly frame the latter for deadline management, reducing misselection risk.
All tools share the jp_ prefix and mostly follow verb_noun patterns (is, add, calc). The exception is jp_business_days_between, which uses a noun-preposition-noun structure, and 'calc' is abbreviated while others are full words. Overall, the pattern is consistent enough to be predictable.
With 4 tools, the server is well-scoped for its narrow domain. Each tool addresses a specific, necessary operation (check, add, count, deadline) without unnecessary bloat or missing essentials.
The domain of Japanese business days is thoroughly covered: checking a date, adding/subtracting business days, counting between dates, and computing deadlines. No critical operations are missing; a holiday-listing tool would be nice but is not essential for common use cases.
