UCP COMMERCE

AI Agents Buy From Your Store

Pass-through to Shopify / WooCommerce

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.

Dual Protocol Access

  • UCP REST API at /.well-known/ucp (schema v0.1.0)
  • MCP commerce tools injected into existing MCP server
  • Google Pay pass-through -- Wrenda never touches payment credentials
  • Domain-scoped KV sessions with 30-minute TTL
  • Operation logging for analytics and debugging

PLATFORM ADAPTERS

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
