What you can do with this MCP connector
This MCP Server connects your agent straight to the official foreign exchange rates from Brazil's Central Bank. You get reliable, current data for financial modeling and cross-currency calculations without needing an API key. You'll find five tools here:
get_cotacao_dolar gets the current PTAX quote for the US Dollar, giving you both the buy and sell values. get_cotacao_moeda fetches the current buy/sell exchange rate for any foreign currency code you specify, like EUR or GBP. To look at recent history, get_dolar_periodo retrieves the historical PTAX dollar rate series for a period up to one year.
If you need deep, long-term analysis, get_dolar_sgs pulls the commercial dollar series (buy/sell) using SGS. You can check every single currency code available in the Central Bank's system using listar_moedas, which lists all 150+ codes.
Need to crunch numbers? You're set. You use get_cotacao_dolar for today's official PTAX buy and sell rates on the dollar. You use get_cotacao_moeda to pull the current buy and sell rate for any other currency pair. If you're tracking recent market movements, get_dolar_periodo gives you the historical PTAX dollar rate series for up to a year.
For historical depth, get_dolar_sgs provides the commercial dollar series (buy/sell) using SGS, perfect for long-term studies. If you don't know what codes you need, listar_moedas gives you a complete list of all 150+ currency codes in the system.
How BCB Câmbio MCP Works
- 1 Your AI client calls a specific tool (e.g.,
get_cotacao_moeda) and provides the required parameters, like the currency code and date range. - 2 The MCP Server executes the call against the Central Bank’s data sources, fetching the specific rate data.
- 3 Your agent receives the structured financial data, which you can then use for immediate calculations or reporting.
The bottom line is you get direct, structured access to official Brazilian exchange rates from the Central Bank.

Real-World Use Cases
Valuing a Multinational Portfolio
A financial analyst needs to value a portfolio holding assets in Euros, Yen, and Pounds. They ask their agent to 'Calculate the BRL value of 1M EUR, 500k JPY, and 2M GBP based on today's rates.' The agent uses get_cotacao_moeda three times, pulling the current buy/sell rate for each currency and providing a single, summed BRL total.
Analyzing Long-Term Market Swings
A data scientist wants to see how the dollar behaved over the last decade. They use get_dolar_sgs to retrieve the SGS series data, which offers a deeper, more stable historical record than the standard PTAX period tool. This lets them build a reliable trend line for forecasting.
Checking Compliance for a Client Payment
A treasury manager needs to confirm the exact official rate for a payment coming in from France. They use get_cotacao_moeda with the EUR code and the current date. The agent confirms the precise buy/sell rate, ensuring the transaction adheres to the Central Bank's official guidelines.
Comparing Rate Sources
A quantitative researcher wants to compare the official PTAX rate (short-term) versus the commercial SGS rate (long-term). They run get_cotacao_dolar and then use get_dolar_sgs side-by-side, allowing them to immediately spot any differences between the two official data streams.
The Tradeoffs
Assuming the rate is always available
The user just asks, 'What's the rate for the Brazilian Real?' (The BRL is the base currency and not listed in the tool's scope).
→
You don't query the base currency. Instead, use listar_moedas first to confirm the currency code is supported, and then use get_cotacao_moeda for any foreign currency pair.
Trying to get a rate for a non-standard currency
The user requests a rate for a niche currency not supported by the Central Bank database.
→
Run listar_moedas to check the full catalog of 150+ codes. If the currency isn't in the list, you know the rate isn't available through the BCB Câmbio MCP Server.
Using the wrong history tool
Trying to get a 5-year history using get_dolar_periodo because it seems simple.
→
Remember that get_dolar_periodo is limited to one year. For anything longer, use get_dolar_sgs to access the specialized, long-term commercial series data.
When It Fits, When It Doesn't
Use this server if your workflow absolutely requires rates from the Central Bank of Brazil. You need the official, authoritative data for compliance, modeling, or reporting. Use get_cotacao_dolar for today's USD benchmark, and get_cotacao_moeda for any other single currency pair. If you need to compare rates across time, check the tool: get_dolar_periodo handles the recent, standard PTAX history (up to 1 year). For deep, multi-year financial analysis, the get_dolar_sgs tool is the correct choice because it accesses the more flexible commercial series. Don't use this if you only need general market estimates; this tool is strictly for official BCB data. If you just need a list of currencies, run listar_moedas first.

Available Capabilities
Manually tracking currency rates is a nightmare.
Today, getting a full cross-currency snapshot means logging into the Central Bank's website, finding the PTAX rate for the dollar, switching tabs for the Euro, and then manually finding the rate for the Yen. You copy the data into a spreadsheet, then cross-reference the dates to make sure everything lines up. It takes ten minutes and requires perfect manual discipline.
With BCB Câmbio MCP Server, your agent handles the whole process. You ask for a multi-currency comparison, and the agent calls `get_cotacao_moeda` for every pair, returning a clean, structured data set. You get the official rates instantly.
BCB Câmbio: Accessing PTAX and SGS Data
Before, pulling a long-term historical rate meant dealing with multiple, often inconsistent data feeds: one for the standard PTAX period, and another for the more reliable but complex SGS series. You'd spend time trying to reconcile the two different data formats and time limitations.
Now, the server gives you two distinct, specialized tools. You can use `get_dolar_periodo` for recent PTAX data, and `get_dolar_sgs` for the deep-dive, long-term SGS data. The data sources are isolated, giving you clarity and reliability.
Common Questions About BCB Câmbio MCP
What is the difference between `get_cotacao_dolar` and `get_cotacao_moeda`? +
Use get_cotacao_dolar when you need the official PTAX rate for the US Dollar. Use get_cotacao_moeda for any other specific currency code (like EUR or JPY).
Can I get the historical rate for the dollar using `get_dolar_periodo`? +
Yes, get_dolar_periodo retrieves the historical PTAX series for the dollar, but remember it is limited to a maximum of one year per query.
How do I list all the currencies available for rate checking? +
Run listar_moedas. This tool outputs the full catalog of all 150+ currency codes supported by the Central Bank's system.
Which tool should I use for very old financial data? +
Use get_dolar_sgs. This tool pulls the commercial dollar series via SGS, which is designed for long-term historical data, making it better than get_dolar_periodo for multi-year analysis.
When should I use `get_dolar_sgs` instead of `get_dolar_periodo`? +
Use get_dolar_sgs for long-term data. It provides the commercial dollar series (buy/sell) and is more flexible than PTAX for historical tracking. Both tools require specific date formatting.
How do I find the full list of currencies before using `get_cotacao_moeda`? +
You first call listar_moedas. This returns all 150+ currency codes, including exotic ones like CLP or MXN. Then, you pass the desired code to get_cotacao_moeda.
What date format do I use for historical queries like `get_dolar_periodo`? +
The format is MM-DD-YYYY. Remember that get_dolar_periodo has a limit of one year per request. Check the documentation for the exact date rules.
Does the server require an API key for any of the currency tools? +
No, the server doesn't require an API key. You can access all the currency tools directly through your AI client connection.
What is PTAX? +
PTAX is the official BRL/USD reference rate calculated by the Central Bank of Brazil. It's computed from daily consultations with foreign exchange dealers and is used as the benchmark for settling FX contracts, derivatives, and international transactions in Brazil.
Can I query currencies other than USD? +
Yes! The Central Bank holds an active catalog covering more than 150 different foreign exchange currencies against the Real (BRL). The AI will fetch daily crosses simply by mentioning the currency ticker.
Does it require an API authentication key or setup? +
No. The integration interfaces entirely with the Central Bank's open access OData portals. Subscribe the module and engage directly without generating account tokens.
