Perplexity

Code with Real Financial Data

The `get_selic_meta` and `get_cdi` tools let your Cursor agent fetch live interest rates from Brazil's Central Bank. Instead of hardcoding stale values or using mock data, you can have the agent write code that pulls the actual, current rates. Just tell the agent what you need: "Fetch the current CDI rate and store it in a variable." It calls the tool and injects the code and the live value right into your editor. This is great for building financial models or testing API clients.

Build Forecast-Aware Applications

Use the `get_expectativas_selic` tool to pull the full range of market forecasts from the BCB's Focus Report. Your agent can access the median, mean, min, and max projections from financial institutions. This lets you build apps that react to market sentiment. For example, you can ask the agent to write a function that flags an alert if your internal forecast deviates too much from the market consensus pulled via the MCP server.

A Smarter MCP Server for Cursor

This server is more than just an API wrapper. It gives Cursor's agent the context to understand Brazilian financial data. Ask it to compare the target Selic (`get_selic_meta`) with the daily effective rate (`get_selic_diaria`). The agent can then generate Python scripts, build tables, or write analysis based on that live data, all within your project. It turns your editor into a powerful tool for financial data analysis.
