10 Best Amazon MCP Servers for Sellers (2026)

Short answer

The best Amazon MCP server for most sellers in October 2026 is DataDoe: it puts Seller Central, Vendor Central and Amazon Ads in one schema that any AI client can read and, once you switch on Actions, change, for $97 a month with unlimited Amazon accounts. If you run one US Seller Central account and only use Claude, Amazon’s free Selling Partner plugin is the cheapest start, and for advertising alone Amazon’s free Ads MCP server is worth a look.

One thing to know before you search further: “Amazon MCP server” also brings up AWS’s open-source MCP servers (the awslabs/mcp repository on GitHub). Those are for developers working with Amazon Web Services, not for selling on Amazon. Everything below is about the Amazon marketplace: sellers, vendors and the agencies that run their accounts.

Updated 26 October 2026. Disclosure: DataDoe is built by the Deltologic team, and we rank it first. Every competitor fact below comes from that company’s own pages, read between 12 and 26 October 2026; prices are monthly list prices in USD.

The 10 at a glance

How we ranked them

• Coverage: how much of an Amazon business the AI can see. Seller Central, Vendor Central and Amazon Ads, and whether they sit in one place.
• Write access: whether the AI can change listings, prices, shipments or campaigns, and how those changes are controlled.
• History and freshness: how far back the data goes and how often it is updated.
• Price at scale: the cost for one account and for ten.
• Openness: which AI clients work, and whether the data also reaches a warehouse, an API or a spreadsheet.

The top 10 Amazon MCP servers

1. DataDoe — the full Amazon data layer

Best for: brands selling first- and third-party, agencies, and any seller with more than one account. Price: $97/mo with unlimited Amazon accounts, 14-day free trial; heavier AI usage is billed in tokens on top. Setup: about 5 minutes, no SP-API developer approval needed.

DataDoe joins Seller Central, Vendor Central and Amazon Ads in one schema: 130+ tables of orders, fees, settlements, inventory, FBA, returns, purchase orders, Sponsored Products, Brands, Display and DSP. That join is what lets Claude or ChatGPT answer “Which search terms lost money last month after fees and product cost?” in one question instead of three exports. About two years of order history is loaded when you connect, data refreshes daily with orders and ads updated during the day, and the same tables are available over a REST API, in BigQuery and as CSV or Excel exports.

Write access comes through Actions: listings, prices, orders, shipments and Amazon Ads campaigns, bids and budgets. Actions stay off until you enable them, most AI clients ask before a change, and every change is logged. It works with Claude, ChatGPT, Gemini, Cursor, Copilot and any other MCP client. Vendors get the same layer through the Vendor Central API, including Actions for purchase orders and shipments; no other server here can change anything in Vendor Central.

Behind it is Deltologic, an SP-API engineering team since 2020: every customer gets an account manager, replies in about 15 minutes and a free 30-minute call with an engineer each month, and DataDoe is cleared under Amazon’s Data Protection Policy for restricted buyer data. Where it falls short: for a single low-volume seller account, Agent Central’s cheapest tier and the free options below cost less.

2. Amazon Selling Partner plugin — the free official option

Best for: one US Seller Central account, used inside Claude. Price: free. Setup: minutes, from Anthropic’s connector directory.

Launched by Amazon on 23 September 2026, this is a free, first-party remote MCP server for Seller Central, in beta in Claude and live in Amazon Quick. It reads listings, inventory, traffic and sales, can close a finished month against your payouts, and writes listings, prices and the FBA inbound flow, with you approving each action. The limits are real: US stores and third-party sellers only, no Vendor Central, no Amazon Ads, data about two days behind, and one account and one marketplace per question. DataDoe’s Selling Partner plugin review walks through what it can and cannot see.

3. Amazon Ads MCP server — the official route for ads

Best for: advertisers and developers who only need Amazon Ads in chat. Price: no fee listed; in open beta since February 2026. Setup: through Amazon’s Ads developer tools.

Amazon’s own Ads server gives an AI client first-party access to the Ads API: standard tools such as updating budgets and building a campaign end to end, plus an expert tool that writes Amazon Marketing Cloud SQL. It works with Claude, ChatGPT, Amazon Kiro, Bedrock and AgentCore. What it cannot do is connect an ad to what it earned: there are no sales, fees, inventory or listings, so profit per keyword is out of reach. That join is what the DataDoe Amazon Ads MCP adds.

4. Agent Central — fast answers for one seller account

Best for: a single Seller Central account asking common questions. Price: $39, $69, $99 or $159 per seller account per month by order volume, custom above 20,000 orders, plus $19 for each extra Ads profile; 14-day trial. Setup: minutes.

Agent Central is a hosted MCP server for Seller Central and Amazon Ads with a dedicated tool for each common question, which makes simple lookups quick. Writes to bids, budgets, prices, listings and shipments are previewed and run only when you confirm, with hard limits and an audit log, and keys can be scoped to read-only. It keeps your history from the day you connect. It does not cover Vendor Central, and because every seller account is priced on its own, ten accounts start at $390 a month. We compared the two in detail on DataDoe vs Agent Central and listed the other options on Agent Central alternatives.

5. Helium 10 MCP — market research in your AI

Best for: sellers already on Helium 10 Diamond. Price: included in Diamond, $359/mo or $279/mo billed yearly, up to 1,000 calls a month.

Helium 10’s MCP brings its keyword and product estimates into Claude, ChatGPT, Cursor or a custom agent, next to your own account data, and can change tracked keywords, bids and budgets. That market data is something no pure data layer has. The catch is the Diamond plan and the monthly call cap, and there is no Vendor Central. Our DataDoe vs Helium 10 comparison goes into the differences.

6. Seller Labs MCP Genius — pay per question

Best for: sellers who ask a handful of advertising questions a month. Price: free up to 100 tool calls a month (500 in total), $39/mo for 101 to 400 calls; 60-day free trial.

Seller Labs covers Seller Central and Amazon Ads in 10 marketplaces with up to two years of history. It can build and edit Sponsored Products campaigns, bids and budgets; Sponsored Brands and Display are read-only. Data is about two days behind, there is no Vendor Central, and because pricing follows tool calls, deep questions use up the allowance quickly.

7. Windsor.ai — Amazon next to every other channel

Best for: agencies and data teams reporting across many channels. Price: free for one data source with 30 days of history; paid plans from $19/mo.

Windsor.ai is a general marketing connector with Amazon Ads, Amazon DSP, Seller Central and Vendor Central (read-only) among hundreds of sources, available in Claude, ChatGPT, Copilot, Gemini, Perplexity and Cursor. It can change Sponsored Products status and budgets and Seller Central listing text and price. It is strongest when Amazon is one channel among many; it is not an Amazon specialist, and plans are priced by sources and accounts.

8. Nova — a ready-made P&L first

Best for: sellers who want a modelled profit and loss before anything else. Price: from $49/mo per Seller or Vendor Central account; 14-day trial.

Nova is an Amazon analytics app with an MCP connector for Claude, ChatGPT and Gemini. It covers Seller Central, Vendor Central and Amazon Ads, and its finance data refreshes hourly. Its write tools edit costs and tags inside Nova, not your Amazon account, and each account is billed separately.

9. Atomic One — a free Seller Central MCP

Best for: trying an AI on US, Canadian or Mexican seller data at no cost. Price: free, no card.

Atomic One offers a free MCP server for Claude, ChatGPT and Codex covering Seller Central and Amazon Ads, with 13 months of history; the UK and Germany are listed as coming. There is no Vendor Central and no write access is mentioned. The free server is how Atomic One finds customers for its paid managed service: its page says the team may get in touch, and its team members can see connected data.

10. Amazon SP-API MCP — the developer route

Best for: engineers building their own integration. Price: free, plus your time. Setup: your own SP-API developer registration and app.

Amazon’s developer MCP is the raw-API side: it helps you work with SP-API endpoints directly rather than giving you a hosted, joined data layer. It suits teams with SP-API experience who want full control and will handle rate limits, report jobs and storage themselves. See DataDoe vs Amazon’s native MCP for how the two approaches differ.

Which one should you pick?

• You sell on Seller Central and Vendor Central, or run many accounts: DataDoe. It is the only option here that covers Seller, Vendor and Ads, with write access, for every account on one flat plan.
• One US seller account, Claude only, no budget: Amazon’s Selling Partner plugin.
• Ads only, and you are comfortable with developer tools: the Amazon Ads MCP server.
• One seller account, simple questions, lowest paid price: Agent Central.
• You need keyword and product research data: Helium 10 on Diamond.
• Amazon is one channel among many in your reporting: Windsor.ai.
• Vendors connecting AI to Vendor Central: see our guide to connecting Vendor Central to AI.

What about Jungle Scout?

Jungle Scout launched its own MCP in July 2026, aimed at brands and enterprises and available on request, so it is not a self-serve option for most sellers yet. We compare it with DataDoe in DataDoe vs Jungle Scout.

Servers to add next to your Amazon MCP

An Amazon MCP server is the core of the stack, not all of it. The AI client is the conductor, so you can add general servers alongside it: Slack for daily summaries and alerts, Google Sheets for handing numbers to your bookkeeper, and n8n for automations that run on a trigger. Start with the Amazon data, then add these as your workflows need them.

Bottom line

Free first-party servers from Amazon now cover the simplest cases: one US seller account in Claude, or ads on their own. As soon as you sell through Vendor Central, run more than a couple of accounts, want ads joined to profit, or need history and a warehouse, you need a data layer. Try DataDoe free for 14 days: about 5 minutes to set up, no SP-API approval needed. For the Claude setup itself, follow our Claude setup guide.

Frequently asked questions

What is the best Amazon MCP server for sellers?

For most sellers it is DataDoe: Seller Central, Vendor Central and Amazon Ads in one schema, readable by any MCP client and writable through Actions, for $97 a month with unlimited Amazon accounts. For one US seller account in Claude, Amazon’s free Selling Partner plugin is the cheapest start.

Is there an official Amazon MCP server?

Yes, more than one. Amazon’s Selling Partner plugin (September 2026) covers US Seller Central in Claude and Amazon Quick, the Amazon Ads MCP server (open beta) covers advertising, and the SP-API MCP is for developers. None of them covers Seller Central, Vendor Central and Ads together.

Is an Amazon MCP server the same as an AWS MCP server?

No. AWS publishes open-source MCP servers for Amazon Web Services, which help developers work with cloud services. The servers on this list connect an AI to your selling data on the Amazon marketplace.

Which Amazon MCP servers support Vendor Central?

DataDoe and Nova cover Vendor Central, and Windsor.ai reads it. Amazon’s Selling Partner plugin, Agent Central, Helium 10, Seller Labs and Atomic One do not.

Can an Amazon MCP server change things in my account?

Several can. In DataDoe, Actions stay off until you enable them, most AI clients ask before a change, and every change is logged. Amazon’s plugin asks you to approve each action, and Agent Central previews each change and runs it only when you confirm.

How much does an Amazon MCP server cost?

Amazon’s Selling Partner plugin, the Amazon Ads MCP server and Atomic One are free. Paid options are priced either per account, such as Agent Central from $39 and Nova from $49 per account a month, or per plan, such as DataDoe at $97 a month for unlimited Amazon accounts.

Which Amazon MCP server is best for agencies?

DataDoe, because one plan covers every seller and vendor account you connect. With per-account pricing, ten seller accounts on Agent Central start at $390 a month before extra Ads profiles.
