List CNAE sections in Claude Code

Pipe the output of `list_secoes_cnae` directly into your shell scripts. This tool provides the foundational data for your automated compliance pipelines. It returns structured JSON that your CI/CD processes can parse immediately. You get the 21 economic sections without leaving your CLI session.

Automate division and class lookups

Run `list_divisoes_cnae` to fetch the specific divisions you need for your daily batch jobs. It integrates with your existing terminal tools to keep your data current. When your pipeline needs to filter by class, use `list_classes_cnae`. It provides a filtered list of codes that you can feed into downstream validation logic.

Extract subclass details in production

Deploy `get_subclasse_cnae` to extract detailed subclass info in real-time. It is built for headless environments where speed and accuracy are the priority. For bulk operations, `list_subclasses_por_classe` returns every subclass under a given category. Your scripts can ingest this data to update local caches and ensure regulatory compliance.
