AI crawler audit

0 of 20 AI user-agents reached the homepage.

What the agent sees vs what you wrote

Could not read this store's products: the product feed (/products.json) returned 429, the homepage lists no products, the collection page lists no products, the sitemap returned 429, there were no product pages to read. The store refused our requests (HTTP 429), so it may refuse AI agents that read it the same way.

This is Shopify's Global Catalog - the index AI shopping agents read, not your live page. Price and stock update in real time; other fields lag a re-ingest. The inferred fields above come from Shopify's pipeline and cannot be edited or overridden directly - you only influence them by improving your source product data.

What this means for mizzenandmain.com

On mizzenandmain.com (Shopify), 3 of 9 readable agent standards are in place: Mcp, Ucp, Wikidata. Missing: Webmcp, A2a, Anp, Ap2, Openapi, Llms Txt.

Without JavaScript, your brand name still appears in the raw HTML, so crawlers that do not run JS can read it (detected a nextjs-data-blob hydration shell).

mizzenandmain.com scores higher than 45% of the 127 sites checked here so far; the average readiness score is 24/100.

Make mizzenandmain.com agent-ready on Shopify

mizzenandmain.com runs on Shopify, which does not expose MCP or an A2A card out of the box. Add them through an app or a headless route at /.well-known/mcp.json and /.well-known/agent.json, and confirm the theme renders brand content in the no-JavaScript HTML. Start with Webmcp.

Frequently asked questions

Are these real probes or AI guesses?

Real probes. We fetch the actual files, run a real MCP initialize handshake, and validate A2A cards against their schema. No model decides a verdict.

Does mizzenandmain.com need every standard to pass?

No. Start with the highest-impact gap above, then add the rest. Most sites win the most by shipping a working MCP endpoint and keeping the crawler path clean.
