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:

    "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/"
      ]

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.
