The Pain of Piecing Together Financial Benchmarks
Today, getting a complete picture of Brazilian interest rates means jumping between several official websites. You check the central bank for the SELIC target rate; then you switch to another source to find the CDI benchmark. Finally, you need to pull a separate report just to see what analysts are predicting for next year's rates. It’s a tedious cycle of clicking, downloading PDFs, and copy-pasting figures into your spreadsheet.
With this MCP connection, that manual effort vanishes. Your agent handles the data retrieval from all four necessary sources—the daily rate, the target rate, the CDI benchmark, and future expectations—and delivers it clean and ready to use. You get a single source of truth.
Use `get_selic_diaria` for Real-Time Rate Tracking
Normally, you have to wait for the market close or check different data feeds to get an accurate snapshot of how the SELIC rate performed overnight. This often leaves a time gap between when the information was published and when your model can use it.
Now, `get_selic_diaria` provides immediate access to that effective daily rate. You instantly know what happened in the market without having to wait for end-of-day reports.
What your AI can actually do with this
This connector gives your agent direct access to key Brazilian interest rates, letting you model how changes in the economy affect financing costs. You don't have to visit multiple government sites or piece together data from different reports. Instead, you can ask for a comprehensive view—for example, comparing today’s daily SELIC rate against what analysts predict next quarter.
It lets your workflow monitor whether market expectations (the Focus Survey) are keeping pace with the central bank's actual decisions. Since Vinkius hosts this MCP, you connect once from any compatible client and get all four data points needed for accurate financial modeling.
019d7559-a484-736b-8c61-03bbf50799f6 Here's how it actually works
The bottom line is you get all critical Brazilian interest rate metrics in one clean output package, eliminating manual data aggregation.
First, prompt your agent with the specific rates you need; for example, 'What is the current SELIC target and what are the Focus expectations?'
Your agent sends a structured request through this MCP to gather the required data from the various central bank endpoints.
It returns a consolidated object containing the official rate settings, daily movements, CDI benchmarks, and market forecasts.
Who is this actually for?
Quantitative Researchers, Financial Analysts, and Risk Managers need this. If your job involves modeling asset performance based on central bank actions or predicting capital flows, you're stuck clicking through separate government dashboards to compare rates. This MCP gives you a single access point to all the numbers.
Builds Python scripts that need reliable, structured inputs for SELIC and CDI benchmarks, running models that require historical or future rate data.
Prepares reports comparing the central bank's official actions (SELIC meta) against market sentiment (Focus expectations) to advise clients on investment timing.
Models portfolio sensitivity by continuously checking the daily effective SELIC rate and CDI movements to calculate potential exposure shifts.
What Changes When You Connect
You can instantly compare the official SELIC target rate (via get_selic_meta) with the actual daily movement (get_selic_diaria), letting you see if policy execution is deviating from the stated goal. This saves hours of manual cross-checking.
Modeling becomes faster when you combine the historical data for CDI from get_cdi with future projections using get_expectativas_selic. You can run full scenario analyses without juggling multiple tabs.
Instead of reading through complex government reports, your agent summarizes the key numbers—the median and average market forecasts—using get_expectativas_selic, giving you an immediate read on analyst mood.
The MCP allows your code to track not just the headline rate but also the specific interbank rates. You can use get_cdi alongside other data points to accurately gauge fixed-income performance.
You avoid making assumptions about which rate is most important. By having access to all four distinct endpoints, you build models that account for every variable: target, daily, CDI, and expectation.
See it in action
Forecasting Bond Performance
A bond fund manager needs to predict yield changes. They ask their agent to combine the current get_cdi rate with the median projection from get_expectativas_selic. The agent delivers a comprehensive report, allowing the manager to adjust their portfolio weeks in advance.
Analyzing Policy Drift
A risk analyst suspects the central bank's stated goal isn't matching reality. They prompt for get_selic_meta and compare it directly with get_selic_diaria. The agent flags any significant difference, pointing to potential policy drift.
Building a Rate Dashboard
A data science team needs a dashboard feed. They instruct their agent to pull the most recent CDI rate via get_cdi and then append it with the official SELIC target from get_selic_meta, creating a single, authoritative source for daily display.
Stress Testing Scenarios
A credit portfolio manager wants to stress test assets against varied future conditions. They ask the agent to pull multiple data points: get_selic_diaria (current), and use get_expectativas_selic (future) to build three separate, quantifiable risk profiles.
The honest tradeoffs
Comparing rates manually
Opening the central bank site for the SELIC rate, then opening a dedicated CDI site, and finally running a separate Focus report. It takes 20 minutes of clicking and copy-pasting.
Use this MCP to let your agent pull all four data points—get_selic_meta, get_cdi, get_selic_diaria, and get_expectativas_selic—in a single request. Your AI client handles the assembly.
Assuming redundancy
Running only get_selic_meta because it seems like the 'main' rate, then forgetting to check how that compares to today’s actual market activity.
Always cross-reference the stated goal (get_selic_meta) with the daily reality provided by get_selic_diaria. The difference is where the insight lives.
Ignoring market sentiment
Building a forecast model only on today's rates, without factoring in what analysts actually expect for next quarter.
Don't forget to include get_expectativas_selic. Future rate consensus is often more predictive than current data.
When It Fits, When It Doesn't
Use this MCP if your analysis requires correlating multiple distinct rates: the central bank's set target, the day-to-day effective rate, a major interbank benchmark, and market forecasts. It’s perfect for quantitative models that need to account for policy divergence or long-term trend prediction.
Don't use this if you only need one single number, like just the current SELIC rate. If all you want is the target rate, get_selic_meta works alone. But because most financial decisions require context, relying on the full suite of tools gives you maximum coverage and minimum risk of missing a key comparison point.
Questions you might have
How do I use get_cdi? +
You call get_cdi when you need the primary benchmark rate for fixed income investments. This rate is crucial because it informs the valuation of most local assets.
Is get_selic_meta different from get_selic_diaria? +
Yes, they track two different things: get_selic_meta gives the official goal set by COPOM. get_selic_diaria shows what the rate actually was overnight, which can reveal policy deviations.
What does get_expectativas_selic provide? +
get_expectativas_selic pulls market consensus data from the Focus Survey. It gives you a range (median, min, max) of what financial institutions predict for future rates.
Can I compare CDI and SELIC targets easily? +
Yes. You combine get_cdi and get_selic_meta. This comparison is vital for understanding the premium or discount applied to fixed-income assets relative to the central bank's stated policy goal.
How often does the rate retrieved by `get_expectativas_selic` update? +
The data updates every Monday when the BCB releases the official Focus report. This means you get market projections right after the institutional consensus is set.
What types of investments are referenced by the rate from `get_cdi`? +
The CDI serves as a key benchmark for most fixed-income products in Brazil. Specifically, it tracks rates for CDBs, LCIs, and DI funds.
What should I do if the query for `get_selic_diaria` fails? +
If the daily rate request fails, check your network connection. You can also try rephrasing the prompt or running the tool command again to get the most current effective overnight rate.
Can I combine `get_selic_meta` and `get_cdi` in one workflow? +
Yes, you can chain these functions within your AI client's agent. This allows you to immediately compare the central bank's target rate against the interbank benchmark.
What is the difference between Selic and CDI? +
Selic is the overnight rate for government bond-backed interbank loans, set/targeted by the COPOM. CDI is the interbank rate for unsecured overnight deposits between banks. CDI closely tracks Selic and is the most common benchmark for fixed-income investments in Brazil.
Can I trust the Selic Daily effective values? +
Yes. The module pipes data strictly authenticated by the Brazilian Central Bank. The effective Selic updates are legally suitable for debt recalculations and financial modeling.
Does it include expected adjustments set by COPOM? +
Absolutely. By integrating the Focus expectations array, your AI is acutely aware of forward market opinions preceding actual COPOM rate cut decisions.
