Core Capabilities

• Enroll payment instruments with PayPal's Account Updater utility
• Fetch the status and particulars of an existing subscription
• Process incoming webhook transmissions concerning card lifecycle modifications
• Synchronize your merchant data repository with freshly validated instrument details

Deployment Instructions

# Obtain the source code repository
git clone https://github.com/rishabh17081/paypal-au-subscription-connector.git

# Install required packages
pip install fastmcp requests

Operational Guide

Launching the MCP Gateway

# Configure necessary environmental parameters
export PAYPAL_CLIENT_ID="your_client_id"
export PAYPAL_CLIENT_SECRET="your_client_secret"
export PAYPAL_ENVIRONMENT="SANDBOX"  # Options: "LIVE", "MOCKDB", or "SANDBOX"

# Initiate the MCP gateway process
python -m fastmcp run paypal_au_subscription_mcp.py

Integration with Generative Models (e.g., Claude)

Incorporate this MCP service into your model's configuration structure:

{
  "mcpServers": {
    "paypal-card-updater": {
      "command": "python",
      "args": ["-m", "fastmcp", "run", "/path/to/paypal_au_subscription_mcp.py"],
      "env": {
        "PAYPAL_CLIENT_ID": "your_client_id",
        "PAYPAL_CLIENT_SECRET": "your_client_secret",
        "PAYPAL_ENVIRONMENT": "SANDBOX"
      }
    }
  }
