MCP servers for Amazon sellers in 2026: what each one reads, writes and costs
TL;DR
Amazon's own Ads and Selling Partner MCP servers, AMZ Vault, PPCAssist, Sophie Society, Helium 10, DataDoe and AgentXray compared on data, write approval and price.
An MCP server lets Claude, ChatGPT or another AI assistant read an Amazon seller account and, in some cases, change it. By October 2026 Amazon runs two official ones and several seller-tool companies run their own. They differ on three questions that matter more than the tool count: which data the assistant reads, whether it can change anything on Amazon, and who approves that change.
Every fact below comes from the vendor's own public page, read on 15 October 2026. Where a page does not say something, this article says "not stated" rather than guessing.
The short version
| Server | Made by | Writes to Amazon | Approval before a change | Published price |
|---|---|---|---|---|
| Amazon Ads MCP Server | Amazon Ads | Yes: campaigns, settings | Stated for the one-prompt Sponsored Products campaign | Not stated |
| Amazon Selling Partner connector | Amazon | Yes | "Review and approve every action" | Not stated |
| AMZ Vault | The Burdz, LLC | Yes, staged as diffs | "Nothing reaches Amazon until you confirm" | $49/mo |
| PPCAssist | PPC Assist | Yes | The AI client asks before acting | $49/mo (MCP only) |
| Sophie MCP | Sophie Society | Yes | "None of it happens until you approve it" | $100/month |
| Helium 10 MCP | Helium 10 | Yes, "with your approval" | Yes | Included in the Diamond plan |
| DataDoe | DataDoe | Yes | "A preview before any write reaches Amazon" | $97/mo |
| AgentXray | Avanta Global EOOD | Yes, drafted | Only after a person approves in the browser | From $29/mo |
Amazon's own servers
Amazon Ads MCP Server. Amazon Ads opened it as a beta on 2 February 2026 for Ads partners with active API credentials. It can create, update and delete campaigns, run reporting queries and read account settings and billing data, and it can build a full Sponsored Products campaign from one prompt. For that campaign builder the announcement says the result is ready to launch after review and approval; it does not describe an approval step for the other actions. It works with Claude, ChatGPT, Gemini or a custom agent. No price is published.
Amazon Selling Partner connector. Amazon's Claude connector, listed as added in September 2026, reads sales, inventory and listing performance and can act on the account. It launched for sellers in Amazon's U.S. stores, with international expansion announced as coming later. Amazon's toolkit documentation states that write actions are always drafted for the seller's approval. The pages read for this article do not say whether it reads settlement or fee data.
Neither official server is a profit tool. The Ads server sees advertising; the Selling Partner connector sees sales, stock and listings. Working out what a sale actually earned still means joining those numbers with the fees Amazon deducted, which is the gap the third-party servers compete on.
Third-party servers
AMZ Vault combines Seller Central and Ads data and describes its profit view as settlement-accurate. Changes to bids, budgets, negatives, campaigns and listings are staged as diffs in an approval inbox before anything is sent. It lists 139 tools and 17 marketplaces. The Vault plan is $49/mo for one Amazon account, with a 14-day trial.
PPCAssist reads Amazon Ads, Seller Central and Brand Analytics and lists 81 tools, including budget, pause and negative-keyword actions. Approval sits in the AI client, which asks before it touches Amazon; no server-side approval queue is described. Its homepage and its MCP page disagree on currency and trial length for the MCP plan ($49/mo with a 30-day trial on one, €49/mo with a 7-day trial on the other), so check the checkout page before relying on either.
Sophie MCP, from the Sophie Society agency, reads Seller Central and Ads data and can build campaigns and update listings after approval. It costs $100/month with a 14-day trial, and access opens after the brand is confirmed through an application or a call.
Helium 10 MCP reads account ads and search-term data alongside Helium 10's own marketplace data and can change bids and budgets with approval. It is included for Diamond plan customers; the MCP page does not publish a separate price.
DataDoe bundles MCP, a REST API and BigQuery access in one $97/mo plan with Seller, Vendor and Ads data. It can push changes to Amazon and shows a preview before any write.
Open-source option. MarceauSolutions/amazon-seller-mcp runs locally with the seller's own SP-API credentials. It reads orders, inventory and product details, makes no changes, and estimates profit from a fee calculator rather than from settlements.
AgentXray
AgentXray is an MCP server listed in the official MCP Registry. It reads the seller's settlement line items, so profit and break-even ACoS come from the fees Amazon actually posted, and gaps are shown rather than estimated. Bid, budget and negative-keyword changes are drafted by the seller's own Claude or ChatGPT, and listing title, bullet, image and price changes are drafted and validated by Amazon before submit. Nothing reaches Amazon until a person approves it in the browser; the connector token the assistant holds is refused at the approval endpoint. Each applied change is judged 14 days later on net contribution, or reported as inconclusive. Pricing is from $29/mo, USD, with a 14-day trial and no commission. Setup steps are in the MCP connection guide. Product research and historical price tools are paused.
How to choose
- Decide whether the assistant should only read. If yes, any of these works, and the open-source server costs nothing.
- If it should change things, find where approval happens. Approval in the AI client means the assistant itself is the gate. A server-side queue, where the assistant can propose but not apply, is a stronger guarantee.
- Ask where profit comes from. A fee calculator gives an estimate; settlement data gives what Amazon actually charged. Break-even ACoS, and therefore every bid decision, inherits that difference.
- Check the marketplace. Amazon's Selling Partner connector started with U.S. stores only.
