Scored across 4 tools
Each tool has a clearly distinct purpose: calc for Python expressions, calc_convert for unit conversion, calendar for date operations, and now for current time. There is no overlap or ambiguity.
Names are mostly lowercase and readable, but there is a slight inconsistency: calc and calc_convert share a prefix, while calendar and now are single words of different parts of speech. Still, the pattern is clear and predictable.
With 4 tools, the server is well-scoped for a general utility toolkit. Each tool fulfills a core need without excess or deficiency.
The tool set covers arithmetic, unit conversion, comprehensive date operations (difference, business days, parsing, formatting), and current time with timezone support. No obvious gaps for the intended domain.
