Generate Data-Aware Components

The `get_selic_meta` tool fetches the current Selic target rate. But you don't just get the number, you get working code. Ask Cline to build a component that displays the rate. It will write the function, add the API call using this MCP tool, handle the state, and create the file right in your project. You go from a prompt to a pull request, not just a code snippet.

Write Code That Compares Live Rates

Use the `get_selic_diaria` and `get_cdi` tools to build real-time financial logic. You can ask Cline something like, "Write a function that returns the spread between the daily Selic and CDI." Cline fetches data from both tools, writes the code to perform the calculation, and returns a complete, tested function. It's much faster than looking up docs and writing the boilerplate yourself.

Validate Logic with Cline and Live Data

This MCP Server lets you anchor your unit tests in reality. Before you commit, tell Cline: "Write a test that checks our projection model against the latest Focus report median." Cline will use the `get_expectativas_selic` tool to get the real market forecast. It then writes an assertion that pits your code's output against the Central Bank's published data, giving you a powerful, automated validation step.
