System Documentation

What problem does it solve?

It lets AI agents and engineers exercise a complete UCP vending-machine purchase flow without needing real hardware, so integration work can proceed safely in a local environment.

Core Features & Use Cases

  • End-to-end purchase simulation: Covers discovery, OAuth 2.0 authentication, cart browsing, checkout creation, checkout completion, order polling, and SSE event streaming.
  • Realistic vending scenarios: Simulates normal dispensing, slow fulfillment, empty-lane rejection, and offline-device errors to test retries and fallback handling.
  • Protocol validation: Exposes UCP envelopes, continue URLs, status transitions, totals, and payment-handler behavior so another agent can verify its client against a predictable mock.

Quick Start

Tell the agent to start the UCP mock server and run a full purchase flow against it using the local checkout and order endpoints.
