PayPal MCP Server — AI-Powered Invoicing, Payments, Subscriptions & Disputes

PayPal's official MCP Server provides AI assistants with 30+ tools spanning invoicing, order management, subscriptions, disputes, shipment tracking, and more. It supports both local (stdio) and remote (SSE/Streamable HTTP) deployment with OAuth 2.0 authentication. While it offers broad commerce coverage and early remote MCP hosting, it suffers from split architecture confusion, token expiration issues, open bugs, and less community traction compared to Stripe.
