Ask anything about your store…

Your Amazon store in Claude, ChatGPT or Codex. For free.

Connect Atomic One MCP and get true P&L, inventory, and ad performance, just by asking your favorite AI tool directly, in seconds.

01 / Real profit

True P&L with COGS, not just Amazon fees.

Real margin by ASIN, by campaign, by week. Upload product costs once and every answer is the dollar that lands in your pocket.

Ask“What was my real margin by ASIN last week?”
02 / Unified inventory

One inventory number across FBA and AWD, not five reports.

Available, FBA, and AWD units rolled into a single number per ASIN. No more stitching reports together to know what you actually have.

Ask“Which SKUs will run out in the next 30 days?”
03 / Margin-aware advertising

Ad spend measured against real margin, not just ACOS.

Every campaign, keyword, and ASIN checked against your true cost, so you know which ads are actually profitable, not just efficient.

Ask“Which campaigns lose money after COGS?”

From Seller Central data to decisions, in one connection.

Ask in plain language. Atomic One MCP connects your Seller Central data and your AI tool does the answering.

Not sure where to start?
Use these skills built by Amazon sellers.

We run Amazon stores too, so we turned the reports sellers ask for most into skills. Connect Atomic One MCP first, then add a skill to Claude, ChatGPT or Codex and ask for the report in one sentence.

Coming soon / EU & UK

Are you operating in Europe or the UK?

We will be there soon. Leave your email and we will let you know the moment Atomic One MCP is live for EU and UK sellers.

Honest answers.

What's an MCP?

MCP (Model Context Protocol) is the standard that lets AI tools like Claude, ChatGPT and Codex securely connect to other apps and data, in this case your Amazon store.

What's a skill?

A set of instructions you add to Claude, ChatGPT or Codex so it does a specific job the same way every time, like a weekly PPC audit. Our skills use Atomic One MCP to pull your store's data, so connect it first.

Does this work for my market?

It's live for stores selling on Amazon US and Canada, and for Mexico if you sell through Amazon.com with your inventory in the US. What counts is where you sell, not where you're based. The UK and Germany are next, with more marketplaces after that. Selling somewhere else? Join the waitlist and we'll email you when we launch there.

Is this really free? What's the catch?

Yes, it's free. No card, no trial that turns into a bill. We make it free so Amazon sellers can see what we do. In return, our team may get in touch from time to time. That's the trade.

Do I need a paid AI plan?

Depends on the tool. Claude's free plan works if Atomic One is your first connector; for more than one, you need Claude Pro. Codex works on the free tier. ChatGPT needs a paid plan to use connectors. Atomic One MCP itself is always free.

How long does setup take?

Under 5 minutes to connect. Your data, including the last 13 months of history, is ready within 3 days, and we'll email you when it is.

Do I need to upload my costs?

No, but it's what unlocks your true profit. Without costs, you still get sales, ads and inventory answers. Upload your product costs once (CSV or paste from a sheet) and every answer shows your real margin.

Can I connect more than one store?

Yes. Fill in the form once for each store, ticking the marketplaces it sells on. You can use the same email; just change the store name.

Is my data secure?

Yes. We connect through Amazon's official Selling Partner API, keep each store in its own isolated database and encrypt your data at rest. Only the Atomic One team members who keep your data accurate can access it, and we don't share it with third parties.

Can I disconnect anytime?

Yes. Remove Atomic One from the apps list in Seller Central, or email us at supportmcp@atomic-one.com. We delete your data within 30 days.

How is this different from Amazon's own AI?

Amazon's Seller Assistant only sees what Amazon reports. We add your product costs, real profitability and tools built by Amazon sellers, and it works inside the AI tool you already use: Claude, ChatGPT or Codex.
