Mastercard MCP Tools for Claude Code (12)
These 12 tools become available when you connect Mastercard to Claude Code via MCP:
bin_lookup
Returns comprehensive card information including: issuer bank name, card type (credit/debit/prepaid/commercial), card category (Standard/Gold/Platinum/World/World Elite), issuing country, currency, and special flags (healthcare, payroll, purchasing). Use this to identify unknown cards, validate card ranges before transactions, determine cross-border fees, or understand the cardholder profile. The accountNumberPrefix parameter must be 6-8 numeric digits. Optional parameters (currencyCode, paymentType, merchantCategoryCode) provide more precise results for specific transaction contexts. Identify card issuer, type, and details from the first 6-8 digits of a payment card number
bin_lookup_post
Returns identical card identification data: issuer bank, card type, category, country, and product flags. Use this method when handling sensitive payment data in compliance-focused applications. The accountNumberPrefix should be 6-8 digits. Optional context parameters (currency, payment type, MCC) refine results. Identify card issuer using POST method for enhanced security with sensitive card data
get_merchant
Returns full address, contact information, MCC code, operating hours, and accepted payment methods. Use this to get in-depth information about a specific merchant location after finding it via search. The merchant ID is a unique identifier returned by the search_merchants tool. Get detailed information about a specific Mastercard-accepting merchant
get_place_details
Returns full address, coordinates, MCC code, payment methods accepted, operating hours, and other merchant attributes. Use this after a places search to drill down into a specific location. The locationId is returned by search_places or search_places_by_address tools. Get complete details for a specific merchant place by its location ID
merchant_category_codes
MCC codes are 4-digit numbers that classify businesses by type (e.g., 5411 = Grocery Stores, 5812 = Restaurants, 4511 = Airlines). Use this to understand merchant classifications, filter searches by business type, or decode MCC values found in transaction data. Optional limit parameter controls how many codes to return. List all Merchant Category Codes (MCC) used to classify business types
merchant_industry_codes
Industry codes group related MCC codes into higher-level categories. Use this to understand the hierarchical classification of merchants, analyze industry-level spending patterns, or build category navigation interfaces. List all merchant industry codes for broader business classification
nearby_locations
Returns names, addresses, categories, and distances from the search point. Use this for "what is nearby" queries, travel planning, or finding payment infrastructure in an area. Latitude and longitude are required. Radius in meters defines the search area. Limit controls maximum results returned. Discover points of interest and payment locations near GPS coordinates
search_merchants
Returns merchant names, addresses, MCC codes, and precise coordinates. Use this to find nearby payment-accepting locations, analyze merchant density in an area, or build "find merchants near me" features. Latitude and longitude are required as strings (e.g., "-23.5505", "-46.6333"). Radius is in meters (e.g., 5000 for 5km). Optionally filter by MCC category code (e.g., "5411" for grocery stores, "5812" for restaurants). Limit controls result count (max 50). Find Mastercard-accepting merchants near specific GPS coordinates filtered by category
search_places
Returns detailed merchant information including whether they accept Apple Pay, Google Pay, contactless payments, and their MCC classification. Use this when users need to find payment-accepting locations with specific digital wallet support. Latitude and longitude are required as numbers. Distance is in kilometers. Optionally filter by country code (ISO 3166-1 alpha-2) and payment capabilities (hasApplePay, hasGooglePay). Search for merchant places using GPS coordinates with payment method filters
search_places_by_address
The API geocodes the address internally. Returns nearby merchants with payment capability details (Apple Pay, Google Pay, contactless). Use this when users provide an address rather than GPS coordinates. Required: address line 1, city, country code, and postal code. Optional: state/province code (countrySubdivisionCode) for more precise results. Example: addressLine1="1600 Amphitheatre Pkwy", city="Mountain View", countryCode="US", postalCode="94043". Search for merchant places using a street address instead of coordinates
submit_fraud_report
This is a critical tool for issuers and processors to flag fraudulent transactions in real-time. Required fields: accountNumber (card number), transactionAmount, transactionCurrency (ISO 4217), and fraudTypeCode. Fraud type codes: "01" = Stolen Card Fraud, "02" = Never Received Card, "03" = Fraudulent Application, "04" = Counterfeit Card Fraud. Optional: fraudAmount (if different from transaction amount), transactionDate (YYYY-MM-DD). Use this only for confirmed fraud cases — never for suspected or disputed transactions. This helps Mastercard improve fraud detection and reduce false positives across the network. IMPORTANT: This action should only be performed by authorized fraud management personnel. Report a confirmed fraudulent transaction to Mastercard Fraud and Loss Database
validate_account
Returns validation status (VALID/INVALID), account type, and issuer information. Use this to verify card validity before processing transactions, reduce declined transactions, or perform account verification during onboarding. Required: accountNumber (full card number). Optional: expiryDate (MMYY format), cardholderName for enhanced validation. Handle card numbers securely — never log or store full PANs. Validate a payment card account number to check if it is active and valid
