Scored across 3 tools
Each tool has a clearly distinct purpose: viewing SMS history, retrieving available numbers for a country, and listing countries. There is no overlap or ambiguity between them.
All tool names follow a consistent verb_noun snake_case pattern (view_sms_history, get_number_by_country_id, get_all_countries). While 'view' and 'get' are different verbs, the overall style and structure are uniform and readable.
With 3 tools, the server is well-scoped and within the ideal 3-15 range. Each tool covers a necessary aspect of the virtual number workflow without unnecessary bloat.
The tool set covers the full core workflow: discover countries, get available numbers for a country, and view SMS history for a number. There are no obvious gaps for the stated purpose of a virtual number service.
