AI integrations for Amazon sellers

Connect ChatGPT and Claude to your Amazon business through Apex

Ask about your profit, stock, supplier scans and purchase orders in plain English, and get answers from your own Apex data. On the Pro plan your assistant can also prepare drafts for you to review. It can never submit an order, spend money or change a live price.

What you can ask

Five questions sellers ask most, and what happens behind each one. Pick a question to see what you need in place first, what Apex hands your assistant, and where it stops.

You askRead only

“Which profitable products should I reorder?”

What you need first

Your Amazon account connected to Apex, and your products in your Apex database with their costs.

What Apex gives the assistant

Your profitable products that are lowest on stock, with days of stock left, sales velocity and Apex's recommended restock quantity.get_restock_recommendationsget_inventory

A typical answer

Three products you already sell are profitable and under two weeks of stock. Example product A has about 6 days left at roughly 20 sales a day, with a recommended restock of 120 units. Want me to put these on a draft purchase order?

Illustrative example with made-up products and numbers, not a real seller’s data.

What you do next

Ask it to draft the purchase order (Pro), or build the order yourself in Apex Blue.

Good to know

Profit comes from the costs in your database, so a product without a cost cannot be ranked.

ChatGPT and Claude

Both connect to the same Apex link and get the same tools. Where you add it, and which plan you need on their side, differs.

How Claude and ChatGPT connect to Apex
	Claude	ChatGPT
Where it works	Claude on the web, the Claude desktop app and Claude Code	ChatGPT on the web
Their plan	Custom connectors are available on Claude's Free, Pro, Max, Team and Enterprise plans. Free accounts can add one custom connector. On Team and Enterprise, an owner adds it for the organization.	Adding a custom MCP server needs a paid ChatGPT plan that allows it. In a Business or Enterprise workspace, your admin's settings decide whether you can add one.
Where you add Apex	Customize, then Connectors, then Add, then Add custom connector	Plugins, then the plus button, then Add custom MCP server
Drafts	Claude asks before running a tool that makes a draft, unless you have told it to always allow that tool.	ChatGPT asks you to confirm each draft call by default.

Other assistants that support remote MCP servers can use the same link, but we have only tested Claude and ChatGPT.

Plans and access

Reading your data works on every paid Apex plan, including the seven-day trial. Drafts need the Pro plan and a separate write link. Either way, the assistant sees exactly what the person who made the link can see in Apex.

Reads

Any paid Apex plan, including the 7-day trial

Profit and loss, by month or any date range
Inventory, restock status and reorder suggestions
Purchase orders and their projected profit
Supplier catalog scan results
Your product database, brands and product research
Repricer listings, results and MAP status

Drafts

Pro plan

A draft purchase order on your Open tab. It is never submitted and nothing is sent to a supplier.
Products added to your database as drafts, never activated. Products you already hold under that supplier are skipped.
A new supplier on your Vendors page. A name you already have is refused.

The person making the link needs edit access to purchase orders, products and vendors in Apex.

Never

It cannot submit or send a purchase order.
It cannot contact a supplier.
It cannot spend money.
It cannot create or send a shipment.
It cannot change a live price or repricer setting.
It cannot delete anything.

New to Apex? Every paid plan starts with a seven-day trial, and reading works during it. Compare plans.

Connect and disconnect

It takes a couple of minutes, and you can switch it off just as fast.

1
Make a link in Apex
Open your account menu, then Connect your AI, and choose Claude or ChatGPT. Apex shows your link once. Make a separate write link there too if you are on Pro and want drafts.
2
Add it to your assistant
In Claude: Customize, Connectors, Add custom connector. In ChatGPT on the web: Plugins, the plus button, Add custom MCP server, with No authentication. The guides below walk through each screen.
3
Ask a first question
Try “What made me the most money last month?” If the assistant does not reach for Apex, switch Apex on in that chat.
4
Turn it off when you want
Turn the link off under Connect your AI in Apex and it stops working at once. You can also remove Apex from your assistant's connector list. A link also stops working if its user loses access to the account.

Limits

Limits exist so one runaway assistant cannot slow Apex down for everyone. Hitting one returns a plain message your assistant can read back to you.

Calls

60 a minute per link, and 4 at once per account

Drafts

10 draft calls a minute per write link, and 100 drafts a day per account (resets at midnight UTC)

Links

Up to 10 live links per account, of which up to 3 can be write links

Results

Lists come back in capped pages so they fit in the assistant's context. Ask for the next page or narrow the question.

Brand searches

Naming a brand uses your plan's monthly brand searches, the same as searching in Apex.

Not available yet

These are planned. They are not live, and we do not give dates.

How it works

For the technically curious. Before an assistant sees a single row, Apex checks who is asking and what they may see, then runs the same code the app itself would.

Swipe the diagram sideways

Permission checkLive

Each tool runs the same subscription and permission rules as the page it mirrors, so an agent never sees more than the person who connected it.

1
The assistant asks
A standard MCP request, carrying your connector link or key.
Live
2
Key check
The key resolves to one Apex account and one user. It is stored hashed and can be turned off at any time.
Live
3
Permission check
The same plan and permission rules as the matching page in the app.
Live
4
The app's own code runs
A read link runs the app's own query and can only read. A write link can only make drafts.
Live
5
Trimmed answer
Rows are capped and shaped so the result fits in the assistant's context.
Live
6
You review drafts in Apex
A draft waits in Apex. ChatGPT and Claude also ask you to approve each draft call. Nothing is submitted or sent unless you do it in Apex.
Live
7
Audit log
Every call through a write link is recorded with the link, the tool and the result, successful or refused.

The data behind it

122M+

Amazon products in the Apex catalog

98M+

UPC and EAN identifiers for matching supplier lists

1.8M+

seller orders synced from Amazon

130k+

products sellers track in their databases

These describe the size of the catalog, not how fresh every price is: prices and offers refresh for the listings Apex tracks, not for every product at once. Other sellers never see your account data.

Developers

Any MCP client that can call a remote server over HTTP with a bearer token can use the same endpoint.

Add Apex as an MCP server
