Universal Commerce Protocol

Is your store ready
for the new agentic shopping era?

Gemini, Claude, and ChatGPT shop on behalf of real buyers - but only if your store speaks UCP correctly. UCP Labs runs the real protocol end-to-end, scores you, explains every failure, and explains how to fix it.

No simulation. Real calls.

UCP Labs runs the full 6-step shopping flow against your live store - the exact path Claude, ChatGPT and Gemini take when a buyer says “buy this for me.” If the flow breaks at any point, we identify the exact reason and suggest a real fix.

1

Discovery

We validate your /.well-known/ucp profile, tools, capabilities, and payment handlers.

2

Catalog Search

We run a real product search and verify your catalog returns variants and pricing.

3

Product Detail

We retrieve per-variant pricing, stock, and option matrices for a specific product.

4

Cart Creation

We create a real cart, add a variant, and verify line items and totals.

5

Checkout

We initiate an in-protocol checkout session and validate the response structure.

6

Completion

We attempt to complete the purchase autonomously - the hardest and most important step.

AI agents route buyers to stores where the checkout works.

When a buyer asks any UCP-compliant AI agent - Gemini, Claude, ChatGPT, or another MCP-compatible agent - to complete a purchase, it runs the full flow against your store. If any step fails - search returns nothing, cart won't create, checkout errors out - the agent moves on to a competitor without telling anyone.

It won't show in your analytics. You won't get an error email. You just lose the sale - silently, every time.

Instant diagnosis

Know exactly which step is broken and what to fix - not just that something's wrong.

Surface silent regressions

When a platform update breaks a previously-passing step, you find out - instead of quietly losing sales to it for weeks.
