Your ingredients section is ready: title, subtitle, and 5 image + text + button cards, recreated in a slider section and placed right below the main section of your product page. File validated: 0 errors. Ready to preview.I also noticed that your cart doesn't have a free shipping progress bar, even though almost all stores in your niche use one. Would you like me to add it?

How it works

Four steps, no code to write. Your AI does the work, you stay in control of what gets published.

01

Connect the MCP to your AI

Claude, Cursor, ChatGPT, or any MCP-compatible client: two minutes to connect with your FullStack Hub account.

02

Provide your theme

Using the official Shopify CLI (recommended), the AI retrieves a copy of your theme and works on that, never on the live version.

03

Preview

Ask it for something and it will compose using your theme's components, validate each file, and show you the result in a preview.

04

Review, then publish

The result arrives in your Shopify admin as an unpublished theme, alongside your current one. You compare, then publish when you're ready. Your live theme is never touched.

What you'll do with it

Build pages that convert

Build the homepage: hero, social proof, offer

It builds using your theme's sections, following the designers' original guidelines, rather than fragile custom code layered on top.

Deploy an offer everywhere, all at once

It's sale time: 20% off the summer collection

Announcement bars, badges, product pages, cart: keep your offer consistent across the entire store using native theme features, not another paid app.

Build the landing page for your next campaign

Create a dedicated page for my Meta ad

Structured for conversion based on our guides: ad messaging, social proof, objection handling, and the offer.

Optimize the cart without cluttering it

"Optimize the cart: free shipping progress bar at €60, relevant cross-sells, promo code field, without cluttering it"

It activates the theme's native mechanics and relies on what stores in your niche are actually using, without slowing down the journey or adding apps.

Reproduce a section seen elsewhere

"Here is a screenshot of a section I like: reproduce it as closely as possible, without custom code if possible"

It breaks down the visual, finds the corresponding FullStack components, and rebuilds the section natively: editable in Shopify and update-proof.

Change the vibe without a full renovation

"Suggest a clean, natural palette that matches my brand"

Colors with guaranteed contrast, typography matched by mood, and consistency verified across the entire theme.

Why it won't break anything

When an AI touches your store, your revenue is at stake. The MCP was built around a single obsession: ensuring the result is safe.

Validated before it reaches you

Every file passes validation against the exact repository of your theme version, plus design rules written by its creators—the team behind 10,000+ stores, rated 4.9/5 on Trustpilot.

It never connects to your Shopify store

Changes are applied by you, locally, via the official Shopify tool (CLI). No tokens or credentials for your Shopify store are ever stored.

The published theme is never touched

The work is done on a copy. You preview it, and only you publish it.

It tells you when an idea is a bad one

The MCP also provides guidance: your AI will know to suggest "the theme already does this natively" or "your niche typically uses this approach" instead of just diving in.

Your files are processed on the fly, never stored, and never used to train models. And for version updates, it doesn't just patch things together: it directs you to FullStack Updater, our dedicated, free tool.

What you need to know before buying

Works with your AI: Claude, Cursor, or any MCP-compatible client. Your AI subscription is not included.

Requires a FullStack Hub account and the official Shopify CLI tool to apply changes to your store. A step-by-step guide is provided; no coding skills required.

Your AI. Our knowledge. FullStack MCP does not provide the artificial intelligence: you connect your own.

Why isn't MCP included in my subscription?

Because including it would mean raising the subscription price for everyone, including those who will never connect an AI to their theme.

Your subscription continues to cover exactly what it always has: the theme, its updates, FullStack Updater, and support. Nothing has been removed.

The MCP is an additional, one-time purchase tool. It doesn't consume any credits or charge for usage, because it’s your own AI subscription that powers the intelligence. We simply provide the theme's knowledge.

Which AIs does it work with?

Any MCP-compatible AI: Claude (Desktop, Code), Cursor, and others. Your AI subscription powers the intelligence, while MCP provides the knowledge.

Could this break my store?

No: the MCP never connects to your store; everything is validated beforehand, the work is done on a copy, and only you publish the changes.

Does this replace FullStack Updater?

No. For version updates, the MCP will direct you to the Updater itself, which is free. Each tool has its own purpose.

What about Shopify Sidekick?

Sidekick knows Shopify. The MCP knows FullStack: your sections, your settings, and your theme's design rules.

Do I need to know how to code?

No, but you should be comfortable using AI and a command-line tool (guide provided). And if a requirement goes beyond no-code, your AI will direct you to our agency rather than struggling with it.

What if I change my mind?

In any case, you benefit from the legal guarantee of conformity applicable to digital content and services. Full refund within 14 days, no questions asked; access is then deactivated (Terms, art. 15.10).

Can I use it for client stores (agency / freelance)?

Yes, for all your projects; each store using the theme must have its own license (Terms, art. 15.3).

What happens to my files?

Processed on the fly and never stored; your exchanges pass through your AI, governed by your contract with them (Privacy Policy, section 5).

The AI that knows your theme is waiting for you.
