About

This MCP server bridges AI agents (like Claude or GitHub Copilot) with the Global Payments API, allowing natural language payment link creation, retrieval, and management with automatic authentication, token management, and comprehensive error handling. Built with TypeScript for type safety and modern Node.js development.

Features

• Payment link creation (single-use and multi-use)

• Payment link retrieval and filtering

• API documentation retrieval (19+ API categories)

Prerequisites

• Node.js 18.0 or higher

• npm

• Global Payments API credentials (Get them here)

• Claude Desktop, VS Code with Copilot, or another MCP-compatible client

  Note: It is recommended that the app being used has limited access. specifically only the LNK related resources should be added in the App permissions

Installation

1. Clone the repository

   git clone https://github.com/globalpayments/mcp-server.git
   cd gpapi-mcp-server/Typescript

2. Install dependencies

   npm install

3. Build the project

   npm run build

4. Create .env file in the project root

   Create a .env file in the TypeScript directory with your credentials:

   # Required: Your Global Payments App credentials (format: APP_ID:APP_SECRET)
   GPAPI_APP=your_app_id:your_app_secret
   
   # Optional: Your Global Payments Account (provide ONE of these, or leave blank for auto-detection)
   # If not provided, the account will be auto-detected from the access token
   # GPAPI_ACCOUNT_ID=your_account_id
   # OR
   # GPAPI_ACCOUNT_NAME=your_account_name
   
   # Optional: Environment (SANDBOX, or PROD, default: SANDBOX)
   ENV=SANDBOX

   Note: The .env file is the recommended way to store credentials. It keeps sensitive information out of your configuration files and makes it easier to manage different environments.

5. Configure Your MCP Client

   For Claude Desktop

   Add to your claude_desktop_config.json:

   {
     "mcpServers": {
       "global-payments": {
         "command": "node",
         "args": [
           "X://absolute//path//to//gpapi-mcp-server//Typescript//lib//index.js"
         ],
         "env":{
          "GPAPI_APP":"XXXXXXXXXXXXXXXXX:XXXXXXX",
          "GPAPI_ACCOUNT_NAME":"XXXXXXXXX",
          "ENV":"SANDBOX"
         }
       }
     }
   }

   For VS Code (Copilot)

   Add to your VS Code MCP settings file (mcp.json):

   {
     "servers": {
       "global-payments": {
         "command": "node",
         "args": [
           "lib/index.js"
         ],
         "cwd": "./",
         "env":{
          "GPAPI_APP":"XXXXXXXXXXXXXXXXX:XXXXXXX",
          "GPAPI_ACCOUNT_NAME":"XXXXXXXXX",
          "ENV":"SANDBOX"
         }
       }
     }
   }

   Note: Ensure you provide the absolute path to your TypeScript project directory in the cwd field. The .env file should be located in this directory.
