A year ago there was almost nothing. Now there are suite vendors, reporting bridges, open-source projects and independent operating layers, all called "Amazon MCP server" and all doing different jobs. We are not going to publish a scoreboard of competitors whose features change weekly. Here are the eight questions that actually separate them — and our own answers, so you can hold us to the same standard.
The sharpest line in the market. Many servers expose reporting to your assistant and leave every change to you in Seller Central. Others prepare and apply listing, price, stock, bid and campaign changes. Check the tool list, not the homepage.
Ours: reads and writes, with approval on every write.
Selling Partner API and Advertising API are separate authorizations. Some servers cover only one. If you want to ask why sales fell and check ad spend in the same breath, you need both in one context.
Ours: both, in the same conversation.
Catalogue and orders are table stakes. Ask about inventory and FBA, pricing and Buy Box context, account health, Sponsored Products at keyword and target level — and, if relevant, Vendor Central.
Ours: all of the above. Vendor Central is covered for purchase orders and PO summaries; payment figures are estimated from PO data, because Amazon's API does not expose real remittances or trading terms for reading.
If you run several brands, or you are an agency, check whether contexts are truly separated and how you switch between them.
Ours: multiple sellers and marketplaces, strictly isolated per request.
Official OAuth on a registered SP-API application is the supported path. A tool asking for your Seller Central password, or driving a browser session, is the pattern Amazon's agent rules exclude.
Ours: official OAuth only; tokens encrypted server-side.
Ask to see it. A proposal should show the SKU or campaign, the value before and after, and how many rows are affected — before anything reaches Amazon.
Ours: explicit confirmation, plus server-side caps on bulk operations.
Flat fee, order tiers, revenue tiers or bundled into a suite. The headline number means little until you know the basis and whether extra seller accounts or ad profiles cost more.
Ours: free plan, then bands calculated from actual revenue. Details.
A proper MCP implementation works with any compatible assistant from one authorization, and the Amazon grant is revocable by you in Seller Central. Single-assistant integrations are a bet on that assistant.
Ours: standard MCP endpoint; revoke from Seller Central at any time.
A table claiming what another vendor does or charges is out of date within a month, and then it is simply wrong information published on our site about someone else. We would rather give you the questions than a snapshot that ages badly.
Every question above can be put to any vendor in an email, and the answers are verifiable in their documentation. A vendor that will not answer question five or six has told you something useful.
Most serious options let you connect one account without paying. Ask each the same question about your own catalogue and compare what comes back.
Connect one seller account free, ask something specific, and check whether the answers match the claims above.
