Scored across 1 tool
With only one tool, there is no possibility of confusion or overlap between tools. The tool's purpose is singular and clearly defined.
A single tool inherently has perfect naming consistency, as there are no other tools to compare it against for patterns or conventions.
A single tool for a calculator server is too few, as it lacks basic operations like subtraction, multiplication, and division, making it severely under-scoped for the domain.
The tool surface is severely incomplete for a calculator, missing essential arithmetic operations (e.g., subtract, multiply, divide) and other common functions, rendering it inadequate for typical calculator tasks.
