Perplexity

Query Brazilian market indices from your CLI

The `list_datasets` tool outputs the entire index of CVM datasets straight to your terminal screen. Claude Code parses this output, allowing you to filter Brazilian financial sources using standard shell utilities. You do not need a browser or a heavy GUI to find the right dataset. Once you identify the dataset, Claude Code runs `get_dataset` to dump the schema. You can pipe this JSON directly into other terminal tools or save it as a local config file for your backend services.

Automate cron jobs for CVM Dados Abertos updates

The `search_datasets` tool lets Claude Code search for updated investment fund data directly from a shell prompt using this MCP Server. Claude Code uses this tool to check for new resources, compare them with local files, and update your data pipelines. It is built for headless automation. By using `get_resource`, Claude Code gets the direct download links for the latest CSVs. It can write a bash script, set up a local cron job, and configure notifications for when new Brazilian corporate filings drop.

Inspect regulatory groups via terminal commands

The `list_groups` tool provides a quick way to inspect thematic divisions like investment funds or public companies over a clean MCP connection. Claude Code queries this list to help you structure your database migrations or backend API routes. You get instant access to the official Brazilian market categories. With `list_organizations`, Claude Code verifies which CVM department published the datasets. This ensures your automated scripts only pull from verified regulatory sources, avoiding broken links and unofficial mirrors.
