Perplexity

Navigate the full CNAE taxonomy

Use `list_secoes_cnae` to pull the 21 primary economic sections for your project. This gives your agent a clear starting point for any classification task. Once you have the section, drill down using `list_divisoes_cnae` to find specific industry divisions. It turns a complex regulatory search into a simple chat query.

Pinpoint specific business activities

Run `list_classes_cnae` to see every class within a chosen division. You get exact figures and labels straight from the official IBGE database. Follow up with `list_subclasses_por_classe` to see the granular breakdown. It keeps your data accurate and prevents manual lookup errors.

Retrieve precise subclass details

Call `get_subclasse_cnae` when you need the final code definition for a specific business activity. Your AI client parses the exact metadata for your tax or compliance reports. This MCP Server removes the guesswork from economic classification. You get the right code every time.
