Pull orders, inventory, listings, and catalog data into Claude or ChatGPT. Edit titles, bullets, descriptions, and search terms without leaving the chat. One endpoint, your full Seller Central or Vendor Central account.
Most MCP servers in this space stop at advertising data. This one keeps going. Your AI agent can ask about your store, your inventory, your listings, and your customers, then take action where you let it.
Read tools are available on connect. Write tools are opt-in during OAuth and gated by plan.
Read-only is the default. Writes are opt-in during OAuth and you can disable them per integration at any time. Every write is recorded in a ChangeSet with the field that changed and the before/after values.
Listing changes are the kind of write you want to be careful with. Here's the path each edit takes.
It shows you the new title, bullet, description, or search terms in the chat. You see the before-and-after side by side.
No edit goes out without you saying yes. If write access isn't enabled for that integration, the proposal is all you get.
Only the fields you changed get sent. Amazon returns ACCEPTED. The update then propagates through their system, usually in a few minutes.
A ChangeSet record captures the tool, the ASIN, the field, and the before/after values, so you can always see what changed and when.
You don't run two MCP servers. The same connection covers Amazon Ads and Seller Central.
Add this URL once in your MCP client. Authorize Amazon Ads, Selling Partner, or both. The available tools change based on what you've connected and what your plan allows.

OAuth handles login. No API keys to manage. JSON config options if your client needs them.
The public amazon-ads-mcp-server package on GitHub is a thin relay. It forwards your calls to our hosted server. You sign in with a Marketplace Ad Pros account, and the free tier is enough to use it. No paid plan required to read.
The repo's name is misleading on this point: it's named for Amazon Ads, but because it relays to the hosted endpoint, it picks up everything the hosted endpoint exposes, including Seller Central tools, once your account has the Selling Partner integration authorized.
If you'd rather skip the package, point your client straight at the hosted URL above. Same surface either way.
Create a Marketplace Ad Pros account at app.marketplaceadpros.com. Free.
From Integrations, pick your country and account type (seller or vendor). Amazon prompts you to authorize.
Paste https://app.marketplaceadpros.com/mcp into Claude, ChatGPT, n8n, or any MCP client. Approve OAuth.
Try "what's running low in FBA?" or "audit my top 10 listings." Reports keep accumulating in the background.
Higher-level walkthrough of what connecting Seller Central gives you, including agency workflows.
Integration Overview12 automated checks per ASIN. Title length, RUFUS optimization, hijacking detection, Amazon's own flags, and more.
Listing Audit30 ready-to-use prompts for inventory health, fee analysis, reorder planning, and cross-data insights.
Prompt LibraryThe public package is a relay to our hosted server, so it picks up Seller Central tools automatically once your account has the Selling Partner integration authorized. The repo's name only mentions Amazon Ads, but the surface follows whatever the hosted endpoint exposes.
You need a Marketplace Ad Pros account, which is free. Read tools work on the free tier. Listing updates and other write tools are gated by your plan. See plans.
The AI shows you the proposed change. You confirm. We submit a JSON Patch to Amazon's Listings API, only with the fields you changed. Amazon returns ACCEPTED, the update propagates, and a ChangeSet record captures the before/after values.
Partially. Vendor Central accounts can use orders, order details, and catalog lookups. Listings, FBA inventory, listing updates, and review requests are seller-only today because the underlying Amazon APIs don't support vendor accounts for those flows.
No. One endpoint, one OAuth flow. The same URL gives you Amazon Ads, DSP, and Seller Central. Tools appear based on which integrations you've authorized and what your plan covers.
Connect Seller or Vendor Central, point your AI client at the hosted MCP URL, and start asking. Free to try.
