Scored across 4 tools
Each tool has a distinct purpose: aggregate counting, listing establishments, looking up a single CNPJ, and explaining data caveats. There is no meaningful overlap or ambiguity between them.
All tool names share the consistent 'empresas_' prefix and use clear Portuguese terms, but they mix noun forms (contagem, cnpj, data_caveats) with a verb form (listar). The pattern is still predictable and readable.
Four tools is a lean but reasonable set for a read-only CNPJ data query server. Each tool covers a core operation, though the set is slightly minimal.
Core read operations are present: count, list, and single-record lookup, plus metadata caveats. However, there is no way to list establishments filtered by CNAE even though counts can be broken down by CNAE, and there is no search-by-name or discovery of available recorte slices.
