Can I identify what bank issued a card just from the first few digits?

Yes! Use the bin_lookup capability with the first 6-8 digits of the card number (the BIN). Mastercard will return the issuer bank name, card type (credit/debit/prepaid), card category (Gold/Platinum/World), issuing country, and flags like whether it's a commercial or healthcare card. For example, BIN 542418 reveals the exact issuing bank and card tier.

How can I find merchants that accept Mastercard near a specific location?

Use the search_merchants capability with latitude, longitude, and a search radius in meters. You can optionally filter by MCC code (e.g., "5812" for restaurants, "5411" for grocery stores). For example, searching with coordinates -23.5505, -46.6333 (São Paulo) and radius 5000 will return all Mastercard-accepting merchants within 5km. Results include merchant names, addresses, categories, and coordinates.

Can I verify if a payment card is valid before processing a transaction?

Yes! Use the validate_account capability with the full card number. It checks Mastercard records to determine if the card is active and valid, returning the validation status (VALID/INVALID), account type (credit/debit/prepaid), and issuer information. Optionally include expiry date (MMYY format) and cardholder name for enhanced validation. This helps reduce declined transactions and fraud risk. Never store full card numbers. handle them securely.

How do I report a confirmed fraudulent transaction to Mastercard?

Use the submit_fraud_report capability with the card number, transaction amount, currency (ISO 4217), and fraud type code. Fraud types: "01" = Stolen Card, "02" = Never Received Card, "03" = Fraudulent Application, "04" = Counterfeit Card. Optionally include fraud amount and transaction date. This submits to Mastercard's Fraud and Loss Database (FLD) to help reduce false positives across the network. IMPORTANT: Only authorized fraud management personnel should use this capability for confirmed cases.

Can I find merchants that accept Apple Pay or Google Pay near me?

Yes! Use the search_places capability with GPS coordinates and set hasApplePay=true or hasGooglePay=true to filter for merchants with those payment capabilities. Returns detailed merchant information including names, addresses, MCC codes, and which digital wallets they accept. For example, searching near Times Square (40.7580, -73.9855) with hasApplePay=true will show all nearby Apple Pay-enabled merchants.

MCP VERIFIED · PRODUCTION READY · VINKIUS GUARANTEED

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.
