Supported Protocols
The demo store exposes 12 protocols. 4 MCP discovery tools work without authentication; checkout requires OAuth. 4 in production (MCP, A2A, UCP, AG-UI), 3 in sandbox (ACP, AP2, x402), 5 coming soon (VIC, KYApay, PayPal, MCAP, WebMCP).
Model Context Protocol — 10 tools for product discovery and checkout
Stripe-based fiat payments in test mode
Google Agent Payment Protocol — mandate-based confirmations
USDC stablecoin payments via HTTP 402
Visa Intelligent Commerce — tokenized card payments
Identity-linked JWT payments via Skyfire
PayPal Orders API v2 — sandbox verified, buyer approval flow
Mastercard Agent Pay — Ed25519 signatures + Stripe pass-through
Agent-to-Agent protocol — task delegation and SSE streaming
Universal Commerce Protocol — 5 checkout tools, AP2 delegation, /.well-known/ucp discovery
Browser bridge for MCP over navigator.modelContext — bundle served, native mode unvalidated
Agent-User Interaction Protocol — real-time SSE, human-in-the-loop checkout, cryptographic confirmation (188 tests)
Guided Scenarios
Pre-built demos that run tool calls step by step
Search for sneakers, add to cart, and complete checkout — the simplest E2E flow.
Search products, compare two options by price and rating, then purchase the best match.
8-signal scoring pipeline in action: agent evaluates trust signals, tier assignment, and rule engine before purchasing.
UCP identity linking provides a 10% gold-tier loyalty discount. Demonstrates legitimate discount vs. fraud detection.
Agent uses UCP but the store only supports AP2/MCAP. Router selects AP2 with translationRequired=true.
A bot-like agent (velocity 1500ms) with promo abuse signals (15 probes) is blocked by R003 + R004 before checkout.
Purchase a high-value item that triggers the human confirmation policy (orders > $100).
