Google handles payment UI → encrypted token

Order Confirmed

Token forwarded to PSP → order lifecycle tracked

When an AI assistant like ChatGPT or Claude wants to help a user buy something, it discovers your commerce tools via MCP, browses your catalog, adds items to a KV-backed session cart, and completes checkout with a Google Pay token -- all without the user leaving their conversation.

Security

Zero PCI scope by design

Wrenda never sees, stores, or processes payment credentials. Google Pay tokens pass through directly to your payment processor (Shopify Payments, Stripe, etc.). Your compliance posture stays unchanged.

  • Payment Token Pass-through -- Google Pay encrypted tokens go straight to your PSP
  • No Card Data Storage -- Wrenda never touches PAN, CVV, or cardholder data
  • Session Isolation -- Domain-scoped KV keys prevent cross-tenant data leaks
  • Rate Limiting -- Per-tool and global RPM limits prevent abuse
