Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 7 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Gathering a full financial picture used to involve logging into five different portals.

You open your browser. First, you check the bank's online portal for liquid cash balances (`get_accounts`). Then, you switch tabs to the credit card issuer site to see available limits and pending bills. Next, you go to the investment platform to pull your fund performance data. Finally, you log into the loan servicer just to confirm mortgage details.

With this MCP server, your agent handles all of that complexity in one prompt. You ask: 'What is my total debt load versus my current liquid assets?' The AI client runs `get_accounts`, `get_credit_cards`, and `get_financing` automatically, returning a single report without you touching another tab.

Open Finance Brasil MCP Server: Unified financial analysis.

Manual cross-referencing is tedious. You must compare the transaction dates from your bank statement against the investment purchase records and then manually reconcile that against the credit card billing cycle to spot discrepancies.

The agent abstracts this complexity away. It executes the necessary tool calls in sequence—for instance, linking a specific `get_transactions` record to an account ID used by `get_accounts`—and presents you with validated, linked data.

What your AI can actually do with this

Listen up. You don't gotta log into seven different banking portals just to get a full picture of someone's money. This server connects your AI agent directly to core Brazilian financial sources, giving it access to everything from basic identity checks to investment portfolio values. It’s the single data pipeline you need.

To start, your agent first pulls the basics: customer identification details like their Name, CPF, and Address using get_customer_data. This context is critical for every other query you run against the system.

When it comes to liquid cash and spending, your agent can list all associated payment accounts. Using get_accounts, it pulls out the account type, agency, number, and what's currently sitting in that balance. If you wanna know how money moves through those accounts, you run get_transactions—you just gotta feed it an Account ID pulled from the previous step to get a full history of spending patterns.

Tracking debt is where this thing really shines. You can pull all linked credit card accounts with get_credit_cards, which gives you the brand, and the total, used, and available limits across the board. If you need specifics on what's due right now, running get_credit_card_bills lets your agent fetch outstanding bills after you provide a specific Credit Card Account ID.

For bigger picture debt—the stuff that lasts longer than a month—you use get_financing. This tool pulls records for long-term contracts, covering everything from auto loans to mortgages and other major financing agreements. It gives the full scope of their committed liabilities.

Then there's the wealth side of things. You can build out a complete investment profile using get_investments, which gathers data on various assets like funds, CDBs, or treasury bonds, showing you what they actually own and how much it's worth. This is your holistic view of their net worth.

By chaining these tools together—starting with identity, getting the current balances from get_accounts, reviewing spending history with get_transactions, checking credit limits via get_credit_cards while also pulling specific bills using get_credit_card_bills, understanding long-term debt through get_financing, and wrapping it all up with asset values from get_investments—your agent builds a complete, multi-layered financial profile.

It’s not just data retrieval; you're performing full financial analysis right in the prompt. You don't need to juggle multiple API keys or write complex SQL queries. Your AI client handles it all through one clean protocol.

Questions you might have

How do I get my spending history using get_transactions? +

You must first call get_accounts to find the specific Account ID. Then, pass that ID into get_transactions. The tool retrieves a detailed list of all transactions for that account.

Does Open Finance Brasil MCP Server show my investment growth? +

Yes. Use get_investments to pull data on funds, CDBs, and treasury holdings to see your current portfolio value.

I need to check my credit card limits; which tool do I use? get_credit_cards? +

The get_credit_cards tool retrieves all linked cards. It gives you the total, available, and used limit for each brand.

How can I check my current loan status? +

Run the get_financing tool. This returns specific details on any active loans or mortgages you have taken out.

What information do I need to provide when calling get_customer_data? +

You must supply the customer's CPF, name, and current address. The tool returns basic identification info, which confirms your agent has correctly scoped the data to that specific person.

If I use get_credit_card_bills but don't have a valid Credit Card Account ID, what happens? +

The process fails because it requires an explicit Credit Card Account ID. Your agent needs to run get_credit_cards first to retrieve the correct identifier before requesting bills.

How do I make sure I pull all my accounts and balances using get_accounts? +

The tool lists payment account details, including type, agency, number, and balance. If you have many accounts, your agent will likely need to run the function multiple times or handle pagination to retrieve every entry.

Can I use get_investments data to compare against my checking balances from get_accounts? +

Yes, you can compare them. You call get_accounts for liquid cash and then run get_investments to see the value of funds like CDBs or treasury holdings.
