Worldpay MCP Server: Seamless Integration for AI Applications

Overview: What is the Worldpay MCP Server?

The Worldpay MCP Server is designed to facilitate secure, scalable payment processing through the Model Context Protocol (MCP). It enables AI applications like Claude Desktop, Continue, and Cursor to interact with the Worldpay API seamlessly. This server acts as a middleware layer, allowing external tools to connect via MCP, thereby enabling advanced capabilities such as making payments, querying transactions, and generating checkout forms.

🔧 Core Features & MCP Capabilities

The Worldpay MCP Server offers a robust set of features designed for developers seeking seamless integration between AI applications and payment processing systems. It supports two primary use cases:

1. Payment Processing: The server can handle both initiating and querying payment transactions through the Worldpay API.
2. Checkout Form Generation: It provides functionalities to create customized checkout forms, supporting both web and React frameworks.

Making Payments

The makePayment process involves sending details such as user credentials, payment amount, and other parameters to initiate a transaction. This feature supports integration with various AI applications, ensuring a smooth interaction with the Worldpay API via MCP.

Querying Payments

The queryPayments capability enables retrieving payment data based on specific criteria such as date range, amount, and entity references. This feature is crucial for managing transactions and maintaining a record of all interactions.

🚀 Getting Started with Installation

To install and run the Worldpay MCP Server, follow these steps:

1. Install Dependencies:

   npm install
   

2. Build the Server Distributions:

   npm run build
   

3. Configure MCP Servers:

   • For stdio server using claude_desktop_config.json:

     {
       "mcpServers": {
         "worldpay-stdio": {
           "name": "worldpay-server",
           "command": "node",
           "args": ["PATH TO server-stdio.js"],
           "env": {
             "WORLDPAY_USERNAME": "USERNAME",
             "WORLDPAY_PASSWORD": "PASSWORD"
           }
         }
     

   • For sse server using environment variables:

     export WORLDPAY_USERNAME=USERNAME
     export WORLDPAY_PASSWORD=PASSWORD
     

4. Run the Server:

   • _stdio: Claudia will start the stdio server automatically.

   • sse: Start the server on port 3001:

     node dist/server-sse.js
     

💡 Key Use Cases in AI Workflows

Example Workflow: Payment Processing for E-commerce Application

A developer building an e-commerce application using Claude Desktop can integrate the Worldpay MCP Server to handle payment processing. This integration ensures secure transactions and provides real-time transaction updates.

1. User Interaction: A user initiates a purchase on the web or mobile app.
2. MCP Client Invocation: The AI application interacts with the McAfee protocol to fetch payment information.
3. Payment Processing: The Worldpay MCP Server processes the payment, utilizing the MCP for secure communication.
4. Transaction Confirmation: Once the transaction is successful, the result is communicated back through the MVP client.

Example Workflow: Checkout Form Generation

For a React-based e-commerce platform using Cursor, generating a checkout form involves:

1. API Integration: The AI application makes an API call to generateCheckoutForm with relevant parameters.
2. Template Customization: The Worldpay MCP Server returns customized HTML/React component and JavaScript code for the checkout form.
3. Form Display: The user is presented with a fully customized checkout form that meets the platform's design requirements.

🔌 Integration with MCP Clients
