Common questions

Is Mastercard Developers MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

This MCP server acts as a bridge between MCP clients and Mastercard Developers resources, offering tools to:

List available Mastercard services
Query API specifications and their operations
Access documentation for each service
Retrieve integration guides for OAuth 1.0a, OAuth 2.0, and Open Finance

Available Tools

Service Discovery

`get-services-list`: Lists all available Mastercard Developers Products and Services with their basic information including title, description, and service ID.

Documentation

`get-documentation`: Provides an overview of all available documentation for a specific Mastercard service including section titles, descriptions, and navigation links.

`get-documentation-section-content`: Retrieves the complete content for a specific documentation section.

`get-documentation-page`: Retrieves the complete content of a specific documentation page.

API Operations

`get-api-operation-list`: Provides a summary of all API operations for a specific Mastercard API specification including HTTP methods, request paths, titles, and descriptions.

`get-api-operation-details`: Provides detailed information about a specific API operation including parameter definitions, request and response schemas, and technical specifications for successful API calls.

Integration Guides

`get-oauth10a-integration-guide`: Retrieves the comprehensive OAuth 1.0a integration guide including step-by-step instructions, code examples, and best practices for Mastercard APIs.

`get-oauth20-integration-guide`: Retrieves the comprehensive OAuth 2.0 integration guide including step-by-step instructions, code examples, and best practices for Mastercard APIs.

`get-openfinance-integration-guide`: Retrieves the comprehensive Open Finance integration guide including setup instructions, API usage examples, and implementation best practices.

Configuration Options

You can pre-configure the server with a specific service or API specification by passing them as arguments. This is useful when you are working with a specific service, and you want to focus your agents

service: URL of the documentation of a service that you want the MCP to focus on e.g. https://developer.mastercard.com/mdes-customer-service/documentation
api-specification: URL of the API specification that you want the MCP tools to focus on e.g. https://static.developer.mastercard.com/content/match/swagger/match-pro.yaml. You can get the link from Download Spec button in the API Reference page of service. NOTE: Specifying this will override any value provided in service configuration.

If you specify service or api-specification then the get-services-list tool will be disabled.

Integration with MCP Clients

To use this server with MCP clients like Claude Desktop, add it to your MCP configuration:

"mcpServers": { "mastercard-developers": { "command": "npx", "args": ["-y", "@mastercard/developers-mcp"] } } }

For Specific Service

"mcpServers": { "mastercard-developers": { "command": "npx", "args": [ "-y", "@mastercard/developers-mcp", "--service=https://developer.mastercard.com/open-finance-us/documentation/" ] } } }

For Specific API Specification

"mcpServers": { "mastercard-developers": { "command": "npx", "args": [ "-y", "@mastercard/developers-mcp", "--api-specification=https://developer.mastercard.com/open-finance-us/swagger/openbanking-us.yaml" ] } } }

Usage with VSCode

For quick installation, use one of the one-click installation buttons below:

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.

NPX

"mcp": { "servers": { "mastercard-developers": { "command": "npx", "args": ["-y", "@mastercard/developers-mcp"] } } } }
