MCP Server for PayPal API Integration

Wrapping PayPal's Orders and Payouts APIs as MCP tools, with the same never-touch-raw-payment-data rule as other payment integrations.

PayPal automationRefund workflow sharing

PayPal's Orders v2 API covers checkout and capture; Payouts covers sending money out. Most MCP integrations only need the former.

Core Tools

  • get_order_status(order_id)
  • create_order(amount, currency, description)
  • issue_refund(capture_id, amount) — require confirmation before calling

Sandbox First

Test every tool against PayPal's sandbox environment before pointing credentials at production — a malformed refund call is not something you want to debug against real money.
