What you can do with this MCP connector
Nubank MX connects your personal bank account to your AI agent. You can run every core banking function—from checking balances and paying bills to executing interbank transfers—using only natural conversation. It's built around 14 tools that handle everything you need for managing Mexican money.
Check Account Status & Info
You can instantly pull your primary Nubank account balance using get_account_balance. For specifics, get_account_info gives you the full profile details on your main Mexico account, including its CLABE number. You'll also get a read on your investments; running get_investments shows the current status and balance of your Cajitas portfolio.
Reviewing Spending & History
Need to know where your cash went? You can pull paginated lists of all recent account activity—deposits, withdrawals, transfers, everything—by using list_transactions. If you're looking for one specific payment, get_transaction pulls the complete details just by providing the transaction ID. For outgoing money, list_transfers keeps a clean record of every SPEI and bank transfer you’ve sent out.
When it comes to credit cards, list_credit_card_transactions gets you the most recent spending history directly from that account.
Executing Transfers & Payments
Want to send money? You use create_transfer for instant SPEI transfers straight to any specified CLABE number. For local payments, pay_bill handles utility bills and services like CFE or Telmex; it pays the full amount unless you tell it otherwise. Before paying, run list_bills to see a clear list of all pending service payments and required utility invoices.
Credit Card Management & Rewards
You've got ways to keep tabs on your credit card spending too. Use get_credit_card_info to pull current data like your limit and due date. If you need to track back, get_credit_card_statement fetches a full statement for any specified month. You can also check out all the recent purchases by calling list_credit_card_transactions.
Don't forget about perks; running list_rewards shows exactly what Nubank reward points or benefits you’ve earned.
Analyzing Your Money Flow
This server doesn't just list data; it gives you insights. get_spending_analytics generates a report that details your spending trends, identifies top merchants, and compares how you spent money across different time periods. This tool lets you spot patterns fast. You can also pull the full transaction history associated with your credit card by running list_credit_card_transactions.
These functions put all your accounts—checking, savings, investments, and credit cards—under one roof so your agent never misses a beat.
How Nubank MX MCP Works
- 1 Subscribe to this server on the Vinkius Marketplace.
- 2 Enter your Nubank API Key and Client Secret into your preferred AI client (Claude, Cursor, etc.).
- 3 Ask your agent a banking question, like 'How much money do I have?' or 'Pay the internet bill.' The agent uses the exposed tools to get an answer.
The bottom line is that you talk to your AI client, and the client talks to Nubank's systems using these specific tools to execute commands.
Who Is Nubank MX MCP For?
Anyone managing personal or professional finances in Mexico. This isn't just for tech folks; it’s for anyone who hates logging into multiple apps—the freelancer needing a quick balance check, the financial advisor reviewing client spending data, or the busy person paying utility bills without opening the mobile app.
Tracks incoming client deposits and sends payments to vendors instantly by calling create_transfer.
Queries a client's spending data across different periods using get_spending_analytics without needing access to the mobile app.
Checks current balances with get_account_balance and pays overdue bills like CFE or Telmex using pay_bill.
What Changes When You Connect
- Check balances instantly. Instead of opening the app, you just ask for it, and
get_account_balancegives you your Cuenta amount in seconds. You get immediate clarity on what you have. - Pay bills without clicking through menus. Need to pay CFE or Telmex? Use
pay_bill. Just give the service name and the agent handles the payment flow directly from your account. - Track every cent spent. The
get_spending_analyticstool gives you a breakdown by category, showing you where your money actually goes—not just raw transaction lists. - Send money faster than before.
create_transferexecutes SPEI transfers to any CLABE number right in the chat window. You confirm it, and the transfer happens. - Full visibility into debt. Use
get_credit_card_infoto see your current limit, outstanding balance, and payment due dates without logging into a separate portal.
Real-World Use Cases
Need to pay the internet bill immediately.
You realize you forgot to pay Telmex. Instead of opening the app, navigating to bills, and finding the amount, you tell your agent: 'Pay my Telmex bill.' The agent runs list_bills first, confirms the outstanding amount, and then executes pay_bill, telling you when it's done.
Client needs to know current funds.
A freelancer client asks for your available balance before paying a vendor. You simply ask your agent, 'What is my current usable balance?' The agent runs get_account_balance and gives the precise figure instantly.
Checking spending habits.
You want to see if you overspent on food last month. You ask your AI agent for a breakdown, running get_spending_analytics. It returns top categories and shows how much more or less you spent compared to the previous month.
Sending money manually.
You need to pay rent via SPEI. You give your agent the CLABE number, amount, and concept name. The agent runs create_transfer, executes the payment, and tells you the new available balance.
The Tradeoffs
Trying to get one specific transaction.
Relying only on list_transactions and scrolling through potentially hundreds of entries until you find the exact $50 charge from a coffee shop last Tuesday. It's slow, tedious, and unreliable if the list is paginated incorrectly.
→
Use get_transaction and provide the specific transaction ID or date range for instant lookup. If you just want to see everything, use list_transactions with appropriate limits.
Confusing history with current status.
Thinking that calling list_transfers will tell you your available money right now. It only gives a list of past outgoing payments; it doesn't factor in pending funds or current balances.
→
Always use get_account_balance if you need to know how much usable cash you have right now. Use list_transfers only when you want an audit trail of what money left the account.
Needing a statement for tax purposes.
Trying to piece together last month's spending by calling multiple listing tools like list_credit_card_transactions and then manually exporting those lists. The data is fragmented and hard to reconcile.
→
Use get_credit_card_statement. This tool pulls the full, official statement for a given period, making it ready for tax or accounting records.
When It Fits, When It Doesn't
Use this server if your core need is executing specific financial actions (send money, pay bills) or getting hard numbers (balance, statements). Don't use it if you just want to 'browse' banking data—use the right tool. If you are checking if a bill needs paying, start with list_bills. If you already know what service and amount, run pay_bill directly. Never assume that simply listing transactions (list_transactions) is enough; if you need to know your cash position, use get_account_balance first. The key decision point: Do you need a list (use 'list_') or a single data point (use 'get_')? Always check the tool name for that pattern.

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 server provides 14 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Paying bills shouldn't require navigating three different menus.
Right now, paying utilities means logging into Nubank, finding the services menu, selecting CFE, entering your account number, checking the due amount against a separate PDF, and then clicking 'Confirm Payment.' It’s three or four different screens and multiple manual steps.
With this MCP server, you just tell your AI agent: 'Pay my internet bill for Telmex.' The agent handles the multi-step process. It confirms service eligibility, pulls the outstanding amount from `list_bills`, and executes `pay_bill` in one go. Done.
Nubank MX MCP Server: Get bank data instantly.
You don't have to switch between the mobile app, a web portal, and an expense spreadsheet just to reconcile one transaction. You can ask your agent about any activity—from `list_credit_card_transactions` to checking cash with `get_account_balance`. The data comes together in chat.
It's direct. No clicking through layers of menus. You talk to the AI, and it runs the right tools immediately. That’s how modern finance works.
Common Questions About Nubank MX MCP
How do I check my current balance using get_account_balance? +
Just ask your agent a simple question like, 'What is my available account balance?' The agent calls get_account_balance and returns the real-time figure. It's fast, no logging in required.
Can I send money to another bank using create_transfer? +
Yes. You must provide the destination CLABE number, the recipient name (if possible), and the amount. The agent uses create_transfer to process the instant SPEI payment.
What is the difference between list_transactions and get_transaction? +
list_transactions gives you a paginated history of many transactions over time. Use get_transaction when you know the specific transaction ID or want details on one single event.
How do I pay an outstanding bill with pay_bill? +
You tell your agent, 'Pay my water utility bill.' The tool first checks pending services via list_bills and then uses that data to execute the payment through pay_bill.
When calling `list_transactions`, how do I handle accounts with thousands of records? +
You must use the limit and offset parameters. This lets your agent pull data in manageable, structured chunks instead of failing on a massive request.
If I need an old statement, what parameters should I pass to `get_credit_card_statement`? +
You specify the exact month and year you want. The tool defaults to the current open statement if you leave those date parameters blank.
What core identifiers does `get_account_info` provide about my Nubank Mexico account? +
It returns essential account details, including your full CLABE number and general profile information. This is critical for verifying routing numbers before any transfer.
How do I change the timeframe when using `get_spending_analytics`? +
You pass a specific period parameter to define custom timeframes. This allows your agent to compare spending across customized date ranges, not just the previous month.
Can I send SPEI transfers to any Mexican bank from my AI agent? +
Yes! Use the create_transfer tool with the recipient's 18-digit CLABE number, the amount in MXN, and an optional concept description. Transfers are processed instantly during banking hours through Mexico's SPEI interbank system.
Can I see which purchases were made with meses sin intereses? +
Yes. Use list_credit_card_transactions to see all your credit card charges. Each transaction includes its installment details — whether it was a single payment or spread across 3, 6, 12, or 18 months interest-free (meses sin intereses), along with the remaining installments.
How does the spending analytics feature work? +
Use get_spending_analytics with a period (last_month, last_3_months, last_year). It returns your spending broken down by category (food, transport, entertainment, etc.), your top merchants, and comparison percentages against your previous period.
