The short answer: enter your domain here and you'll know in under 60 seconds. This UCP ready check runs the same validation that AI agents use to decide whether your store is worth shopping.
The longer answer — what "UCP ready" actually means, why it matters, and what to do about the result — is what this post covers.
What UCP readiness means
A store is "UCP ready" when it publishes a valid manifest at /.well-known/ucp that AI shopping agents can discover, parse, and act on. That's the technical definition.
In practice, there are three levels:
Level 1: Verified
Your manifest exists, returns valid JSON, and passes schema validation against the current v2026-04-08 spec. You appear in the UCP directory. Agents can find you.
As of this month, 4,024 stores are at this level.
Level 2: Agent-functional
Agents can actually shop your store — not just discover it. Your MCP endpoint responds, your product data is clean, your checkout flow completes without errors. You score B+ or higher on the Playground leaderboard.
422 stores are at this level. The gap between "verified" and "agent-functional" is where most common errors live.
Level 3: Optimized
Agents complete purchases reliably across multiple models. Your variant data is clean, your latency is low, your capabilities go beyond the defaults. You score A. Only 9 stores are here today.
The UCP requirements checklist breaks down exactly what each level requires.
How to check your store
Step 1: Run the checker
Go to UCPChecker.com/check and enter your domain. When you check your UCP status, the checker will:
- Fetch
/.well-known/ucpfrom your domain - Validate the JSON against the current spec
- Check your robots.txt for AI bot policies
- Inventory your declared capabilities, transports, and payment handlers
- Verify your UCP compliance and report every error and warning with specific error codes
The whole process takes about 1 second. You'll get a full diagnostic report on your status page.
Step 2: Read the result
Verified (green) — your manifest is valid. You're in the directory. Agents can find you. Check the warnings section for things to improve.
Invalid (amber) — your manifest exists but fails validation. The diagnostic panel shows exactly which fields are wrong or missing. Most invalid manifests are one fix away from passing — usually a missing required field or a misplaced signing_keys.
Not Detected (grey) — no manifest found at /.well-known/ucp. Your store isn't UCP ready yet. See the requirements post for what to publish.
Blocked (orange) — your robots.txt or firewall is preventing access to the manifest. The diagnostic will tell you whether it's a robots.txt rule or an HTTP-level block.
Step 3: Fix what's broken
The checker tells you what is wrong. Here's where to go for how to fix it:
- Platform-specific guides: Shopify · WooCommerce · BigCommerce · Magento
- Manifest reference: /.well-known/ucp developer guide
- Error-by-error fixes: Common UCP errors
- Spec changes: v2026-04-08 update
Step 4: Test with real agents
Schema validation tells you if your manifest is syntactically correct. It tells you nothing about whether an agent can actually buy something from your store. For that, you need UCP Playground — it runs real AI agent sessions against your store and shows you exactly where the flow breaks.
The agent testing data shows that the most common runtime failure is variant mismatches — clean product data matters more than perfect schema.
Step 5: Monitor
Your UCP endpoint is a live API. Platform updates, catalog changes, and CDN reconfigurations can break it silently. Set up UCP Alerts to get emailed the moment your status changes — before agents notice.
How you compare
Once you're verified, see how your store stacks up:
- Compare side-by-side with a competitor or partner store — capabilities, transports, payment handlers, latency.
- Browse your platform — see all verified Shopify, WooCommerce, BigCommerce, or Magento stores ranked by capability depth.
- Check the leaderboard — stores graded A through F on real agent shopping performance.
Why this matters now
UCP adoption is accelerating. 1,400+ new merchants were discovered in April alone. Shopify migrated its entire fleet to the latest spec in four days. BigCommerce, WooCommerce, and Magento stores are appearing every week.
Am I UCP ready? The question isn't whether your store will need UCP. It's whether you'll be ready when agents start shopping — and they already are.
Before you check, it helps to understand the building blocks: capabilities define what your store can do for agents, payment handlers define how agents pay, transports define how agents connect, and product discovery is the flow agents actually run when they shop.
Make sure your listing on UCP Registry is accurate once you're verified — that's how agents find you in the first place.
