For Shopify
Shopify agent readiness
Shopify is the strongest hosted builder on this list for one reason: Shopify ships llms.txt by default on stores since 2026, so the single most-cited agent-readiness file already exists before you touch anything. Everything past that first file still has to be added by hand.
Native ceiling
Best achievable score without fronting
Cloudflare-fronted ceiling
Worker in front of your DNS, zero code changes
What agents currently see
A stock Shopify theme gives an agent a default llms.txt, decent title and meta description handling through the theme editor, an auto-generated sitemap.xml, and forced HTTPS. Product pages usually carry partial structured data (basic Product schema from the theme), but it is often incomplete: missing availability, missing Organization-level JSON-LD, or absent on collection and page templates entirely.
What almost never exists on a Shopify store: agents.md, an MCP server card, a /.well-known/verified.md self-attestation, markdown content negotiation on the storefront, and any x402 signal. Liquid templates can render conditional content, but Shopify does not give you a way to change the Content-Type header per request, which is what content negotiation and a raw markdown response both require.
Your ceiling, and why
85 to 90 natively. Shopify's app proxy and theme editor cover static-file-style routes (you can serve /agents.md and /llms-full.txt content through an app proxy or a Page template) and structured data, but there is no supported way to set custom response headers or a custom Content-Type at the root domain, which blocks content negotiation and limits how an MCP endpoint can be exposed. Fronting the storefront domain with a Cloudflare Worker removes that ceiling entirely: the Worker can inject headers, serve the well-known files, and handle content negotiation before the request ever reaches Shopify, taking the store to 100 without touching checkout or theme code.
Which delivery model fits
The Agent Ready Kit covers the app-proxy and theme-editor pieces (agents.md, llms.txt refresh, structured data, meta hygiene) with paste-ready instructions your Shopify admin or theme developer can apply without touching checkout. If you want the full 100, and your store's DNS can move to Cloudflare, Cloudflare edge delivery is the fit: zero Liquid changes, everything served from the edge.
What is typically failing
- agents.md
- MCP server card
- .well-known/verified.md
- Content negotiation (Accept: text/markdown)
- Structured data (often partial, not absent)
- x402 payment signaling
