Perplexity

Monitor Rates from Your Terminal

The `get_selic_diaria` tool gives you the daily effective Selic rate. With Claude Code, you can call it directly from your command line. The output is clean and simple. Pipe it to `jq` to grab a specific field, or use it in a shell script to trigger an alert if the rate moves. It's a straightforward way to build lightweight financial monitoring tools.

Add a Sanity Check to Your CI Pipeline

Use the `get_expectativas_selic` tool to make your deployment process smarter. This tool fetches the market consensus for the future Selic rate. In your GitHub Actions workflow, add a step that calls this tool via Claude Code. You can then compare your newly trained financial model's forecast against the market's. If they diverge too much, you can have the build fail automatically. This MCP Server becomes an automated guardrail.

Automate Headless Financial Reporting

This server is perfect for automated, non-interactive tasks. Set up a cron job that uses Claude Code to build a daily interest rate summary. Your script can call `get_selic_meta`, `get_selic_diaria`, and `get_cdi` to assemble a complete picture of the day's rates. Format the output and send it to a database, a monitoring service, or a Slack channel. It's set-it-and-forget-it market data.

Common questions about BCB Juros — Selic, CDI e Expectativas Focus MCP in Claude Code

Run `claude mcp add` with the server's Vinkius URL from your terminal. Once added, you can immediately invoke its tools, like `get_selic_meta`, within your shell or scripts. Use `claude mcp list` to check the connection.

Yes, that's a perfect use case. You can write a shell script that calls Claude Code to fetch rates using tools like `get_cdi` and `get_selic_diaria`, then run that script as a cron job for automated reporting.

It provides programmatic access to four key Brazilian rates: the Selic target (COPOM), the daily effective Selic, the CDI interbank rate, and Selic market expectations from the Focus report. All are accessible as simple CLI commands.

After connecting the MCP Server, you can run a command in your script like `claude run bcb-juros.get_selic_meta`. This will output the current target rate, which you can then parse or use as needed.

The server itself only deals with public interest rate data. Every request you make with Claude Code through the Vinkius platform runs in a zero-trust, ephemeral environment. Nothing about your specific request is stored.
