Both tools have completely distinct purposes—one performs arithmetic, the other generates greetings. There is no possibility of confusion between them.

Both tool names are Spanish verbs in infinitive form ('sumar', 'saludar'), following a clear and consistent pattern.

With only two tools, the set feels minimal, but it may be appropriate for a simple demo or utility server. The count is borderline thin rather than excessive.

The server covers its apparent basic scope without dead ends: one math operation and one greeting function. Additional math operations could be considered a minor gap, but the surface is functionally usable.
