Best Amazon MCP servers in 2026: an agency's ranking
The short answer: the best Amazon MCP server for most sellers, brands and agencies is Nova Analytics, because it gives your AI assistant modeled profit per SKU across Seller Central, Vendor Central, Amazon Ads and DSP, with data refreshed during the day. If you have one US seller account and only use Claude, start with Amazon's own Selling Partner plugin. For campaign automation alone, use the Amazon Ads MCP Server.
An Amazon MCP server connects an AI assistant such as Claude or ChatGPT to your Amazon selling accounts, so you can ask questions in plain language and get answers from your own data. MCP stands for Model Context Protocol. Every server speaks the same protocol. What differs is the data behind it, how fresh it is, and what it is allowed to change.
Our experience. At Sitruna, we manage 100+ Amazon accounts for our clients, and we have been using Nova for six months now. It has changed how our team works day to day. Modeled Amazon data flows into our own systems every hour, our team reads it in the Nova App, and our AI assistants query it through the Nova MCP.
A note on the name: Nova Analytics is the Amazon analytics company at novadata.io. It is not related to Amazon Nova, Amazon's family of AI models.
Amazon MCP servers compared
Nova Analytics combines Seller Central, Vendor Central, Amazon Ads and profit modeling, while the other servers listed here each cover part of that. "Not published" means we did not find it on the vendor's own pages.
The ranking
We ranked these servers on one job: giving an AI assistant Amazon numbers you can make a decision on. That puts profit accuracy, freshness and coverage ahead of the number of tools.
1. Nova Analytics: best overall Amazon MCP server
Best for: sellers, brands and agencies who need the right profit number, by SKU and across accounts, inside Claude, ChatGPT, Gemini or Microsoft Copilot.
Nova's Amazon MCP server ranks first because the data is modeled before your assistant sees it. Nova reconciles 370 Amazon transaction lines into 154 P&L lines and joins them with your own COGS, FBM costs and VAT. We did not find a comparable published figure from the other vendors. Your assistant asks for a profit figure and gets one, instead of receiving raw tables and doing the sums itself.
- Coverage: 900+ data points across 23 marketplaces, with 24 months of backfilled history. It reads your Seller Central account, and the Vendor Central MCP server adds sell-in, sell-out, purchase orders, invoices and remittances. Ads and DSP sit alongside.
- Freshness: orders reach Nova within seconds, ad spend and Amazon finance transactions refresh hourly, and other reports refresh daily.
- Costs fixed in the chat: COGS, FBM rates and VAT categories can be set and corrected through the MCP itself.
- Listing edits: titles, bullets, descriptions, backend keywords and product attributes on Seller Central, previewed with Amazon's validation before anything is sent. Write access is enabled per workspace.
The limits: no PPC write actions yet, listing edits do not cover Vendor Central, and price and quantity cannot be edited. Pricing starts at $49 per account, so a large portfolio should ask for a custom plan.
How Sitruna uses it: "Data Share puts clean, structured Amazon data straight into our own stack, so we no longer maintain those pipelines ourselves. The hourly updates mean we spot changes during the day instead of managing accounts on yesterday's data." That comes from our Sitruna case study with Nova. We also run our Vendor Central data through Nova.
What we do with the Nova MCP
The Nova MCP lets our team ask an AI assistant the questions that used to need an analyst and an export. Here is what that looks like for our clients.
- Explain a sales move. When a client's sales shift, we ask whether a known price change, an ads pause or a stock delay explains it, and the answer comes from that client's own dated data.
- Measure a change, before and after. We log dated changes for a client, such as a price cut or a voucher test, then check whether each one shows up as a visible step in daily sales.
- Find the movers. "Which products gained sales last week compared with the week before?" is one question, not a spreadsheet.
- Work across the portfolio. One connection reaches every account we manage, so we can check any client without logging in to each account.
The Nova App and the Nova MCP: how they work together
The Nova App and the Nova MCP read the same Nova data, and together they cover both halves of the job. The app shows your team what is happening. The MCP lets anyone ask why, and act on the answer, in the assistant they already use.
Account managers keep the screen they check every morning, and strategists get answers without building a report. Both are included in the same Nova plan, and your assistant and your dashboard work from the same numbers.
2. Amazon Selling Partner plugin: best first-party option for one US account
Best for: one US seller account, used inside Claude or Amazon Quick.
Launched on 23 September 2026, this is Amazon's own connector. It is the source of truth on its scope, and changes need your explicit approval. It is in beta for US stores, with international expansion promised. Amazon does not list Amazon Ads or Vendor Central for it, and its announcement does not mention your own product costs.
3. Amazon Ads MCP Server: best for advertising only
Best for: Amazon Ads API partners and developers automating campaigns.
Amazon's Ads server can create, update and delete campaigns. It does not hold your landed cost, so it cannot tell a profitable ACOS from an unprofitable one on its own. Many teams will pair it with a data server.
4. Agent Central: best hosted option for a single Seller Central account
Best for: a seller who asks routine questions and wants previewed changes.
Agent Central publishes 180 tools across ads, inventory, finance, catalog and fulfillment in 23 marketplaces. It has no Vendor Central. COGS is not modeled on the server: its own page says your assistant subtracts it. It charges per seller account, which adds up across a portfolio.
5. Helium 10 MCP: best for keyword and product research
Best for: sellers already on Helium 10 Diamond.
It brings Helium 10's research, ads and profit data into your assistant, and can execute bid and budget changes with approval. Its value is the research data your account does not hold. The Diamond requirement is the catch.
6. Seller Labs MCP Genius: best low-cost start for ads questions
Best for: sellers asking a limited number of questions a month.
It covers Seller Central and Ads in 10 marketplaces, with up to two years of history, and it can change Sponsored Products. Billing per tool call means long, multi-step questions use the allowance quickly.
7. sellerboard: best if you already use sellerboard
A read-only connector to your existing sellerboard data. It is useful if your team already trusts that dashboard, and it changes nothing on Amazon.
8. Windsor.ai: best for cross-channel reporting
A general marketing connector that reads Amazon next to other channels, including Vendor Central in read-only mode. It is not built around Amazon.
9. Atomic One: best free test in North America
Free for US, Canadian and Mexican sellers, with 13 months of history. Its team may contact you about its services, and its page says team members can access your data, so read that before connecting client accounts.
Also worth knowing: Marketplace Ad Pros offers an MCP for ads work, and self-hosted SP-API servers exist on GitHub for engineering teams. Check how recently a repository was updated, because the most starred ones can be stale.
Which Amazon MCP server should you choose?
Start from your situation, not from the longest feature list.
The best Amazon MCP server for agencies
For an agency, we would start with Nova Analytics, because three things matter more at portfolio scale than they do on one account.
- Account scoping. On Nova, each team member connects their own assistant by signing in, and sees only the workspaces they belong to. A client invited to their own workspace sees only their own accounts.
- Comparing accounts. One Nova call can cover several accounts in one currency, so "which client dropped yesterday?" is one question, not an export per client.
- What the bill does at scale. Per-account pricing and metered rows both grow with your portfolio. Model your real account count, row volume and action volume before you commit, and ask each vendor for an agency quote.
Our own setup: Nova's Data Share feeds our stack with modeled Amazon data, the team works in the Nova App, and the Nova MCP answers the questions in between.
Five prompts to test any Amazon MCP server
Any server looks good in a demo. Run these on a real account during the trial, and check the answers against numbers you already trust.
- Profit: "What was net profit per SKU last month, after every Amazon fee, ads and cost of goods? List any SKU missing a cost." A good answer flags the gaps instead of guessing them.
- Freshness: "How are sales today compared with the same day last week, by account?" If the server syncs daily, today's numbers will not be there.
- PPC with margin: "Which search terms spent the most with no sales in the last 30 days, and what is the break-even ACOS on those SKUs?" Many servers can answer the first half only.
- Vendor Central: "Which invoices did Amazon short-pay last quarter, and which can I still dispute?" Skip this one if you only sell 3P.
- Safe changes: "Fix the title on this listing, and show me the change before you send it." Check that you get a preview, Amazon's validation and a record of what happened.
Nova publishes 51 Amazon MCP prompts if you want a longer list. Before enabling any write access, check what a server can change and whether you can preview it first. Nova's MCP server for Claude and ChatGPT reads by default and shows listing edits with Amazon's validation before they are sent.
