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.
