Integrating with Claude

To use the connector with Claude, add the MCP server to your Claude configuration:

{
  "mcpServers": {
    "paypal-au": {
      "command": "python",
      "args": ["-m", "fastmcp", "run", "/path/to/paypal_au_subscription_mcp.py"],
      "env": {
        "PAYPAL_CLIENT_ID": "your_client_id",

Webhook Integration

To receive real-time card update notifications, set up a webhook endpoint in your application. This endpoint will listen for and process PayPal's card update events. The connector includes sample code for implementing this webhook functionality.

Environment Configuration

The connector requires the following environment variables:

• PAYPAL_CLIENT_ID: Your PayPal API client ID
• PAYPAL_CLIENT_SECRET: Your PayPal API client secret
• PAYPAL_ENVIRONMENT: The environment to use ("SANDBOX", "LIVE", or "MOCKDB")

Make sure these are properly set before running the MCP server.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
