Connect Claude to your Amazon business through Apex

• An Apex account on a paid plan or the seven-day trial, with your Amazon account connected. Claude reads what Apex has synced, so an account with no Amazon connection and no products gives empty answers.
• Product costs in your Apex database if you want profit, ROI and reorder answers. Apex can only rank what it can price.
• A Claude account. 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.
• For drafts: the Apex Pro plan, and edit access to purchase orders, products and vendors in Apex for the person making the link.

Claude sees exactly what the Apex user who made the link can see, and nothing more. An authorized user with limited permissions makes a link with the same limits.

1. 1

   Open Connect your AI

   Sign in to Apex, open your account menu and choose Claude under Connect your AI.
2. 2

   Click Make my link

   Apex shows a private link once. Copy it straight away. If you lose it, make a new one; the old one keeps working until you turn it off.
3. 3

   Optional: Make a write link (Pro)

   Further down the same page, Make a write link creates a second link that can also make drafts. Keep it separate so you can tell the two apart in Claude.

1. 1

   Open Connectors

   In Claude, go to Customize, then Connectors, then Add and Add custom connector. On a Team or Enterprise plan an owner does this under Organization settings, Connectors, Add, Custom, Web.
2. 2

   Name it and paste the link

   Name it Apex and paste your link as the server URL. The key is already inside the link, so Claude does not need a sign-in. Click Add.
3. 3

   Add the write link too, if you made one

   Repeat with the write link and name it Apex Draft.

Your link looks like this, with your own key at the end:

https://app.apexapplications.io/api/mcp/apx_YOUR_KEY

Claude Code can send the key as a header, which keeps it out of the URL. On the Connect your AI page in Apex, the command appears under your link once it is made. It has this shape:

claude mcp add --transport http apex https://app.apexapplications.io/api/mcp \
  --header "Authorization: Bearer apx_YOUR_KEY"

To remove it later, run claude mcp remove apex.

Start a new chat. Click the + button at the bottom left, open Connectors and make sure Apex is switched on. Then ask:

What made me the most money last month?

Claude should call Apex’s profit and loss tool and answer with your sales, fees, cost of goods and gross profit by month. The first time it uses a tool, Claude asks your permission. You can allow it once or always.

One way sellers use it every week, in a single chat:

1. “Which profitable products are lowest on stock?” Claude reads your restock list and inventory.
2. “Leave out anything with more than 30 days of stock or inbound units.” Claude narrows the list from the same data.
3. “Group what is left by supplier.” So you see one order per supplier.
4. “Draft a purchase order for Example Supplier with those quantities.” With the Apex Draft connector on (Pro), Claude asks your permission, creates the draft and gives you a link to it.
5. Open the draft in Apex Blue, check costs and quantities, and submit it yourself.

Claude cannot submit the order, contact the supplier or send anything. The draft waits in Apex until you act on it.

Claude answers without using Apex

Check that Apex is switched on for this chat under +, Connectors. Mentioning Apex in your question also helps: “Using Apex, …”.

Claude says it cannot connect, or Apex answers 401

The link was turned off, mistyped or cut short. Make a new link in Apex and replace the connector’s URL.

“This link is read-only. Make a write link in Connect your AI.”

You asked for a draft through the read connector. Make a write link on Pro and add it as Apex Draft.

“Write access is part of the Pro plan”

Drafts need the Pro plan. Reading still works on your current plan.

The answer is empty or says there is nothing to show

Apex has nothing to read yet: connect your Amazon account in Apex, add products with costs, or run a supplier scan first.

“Write limit reached” or “Daily limit reached”

You hit the draft limits (10 a minute, 100 a day per account). Wait and try again; drafts already made are waiting in Apex.

New Apex tools do not show up

Start a new chat. If they still do not appear, remove the Apex connector and add it again with the same link.

In Apex: open Connect your AI, find the link under Your links and click Turn off. It stops working straight away, for Claude and anything else using it. Drafts it already made stay in Apex, and the write link’s history stays in the audit list.

In Claude: go to Customize, Connectors, and choose Remove from the menu next to Apex. Removing it from Claude does not turn the link off, so do both if the link may have been shared.

• Claude reads what Apex has synced from Amazon, not Seller Central directly, so figures can be a few minutes behind.
• It cannot upload a supplier price list or start a scan. Run the scan in Apex Green, then ask about it.
• Lists come back in capped pages, so very large questions may need to be narrowed.
• Drafts only: Claude can never submit or send a purchase order, spend money, create a shipment or change a live price.
• The link carries its key, so treat it like a password. Signing in with OAuth instead is planned, not available.
