ChatGPTTL;DR - Key Takeaways
- •There is no official Amazon MCP server for the Selling Partner API. Amazon's own server covers advertising, and it is free.
- •Ranked by criterion rather than overall. Nova wins profit modelling, Search Query Performance, marketplace coverage and multi-account. Amazon Ads MCP wins write actions today. The open source repositories win on free.
- •Nova reconciles net profit per SKU after 40+ Amazon fee types, with your own COGS, FBM cost and VAT. No other server on this list models that.
- •Free and self-hosted exists: community SP-API wrappers on GitHub. The most visible one had 43 stars and was last pushed in April 2025.
- •Every claim below carries a source and a verified date, last checked 30 August 2026.
Thirteen servers an Amazon seller can connect this week. What each one reads, what it can change, and which one wins on the criterion you actually care about. Ecommerce platforms are covered further down; the money question here is Amazon.
The short answer
- Your money, per SKU: Nova. Net profit after 40+ Amazon fee types, your COGS, your FBM costs, across 23 marketplaces. Search Query Performance too, which almost nobody else exposes. Write mode is in beta.
- Changing campaigns today: Amazon's own Ads MCP server. Official, free, and it writes. Use it for execution.
- Free and self-hosted: the community SP-API repositories on GitHub. No profit model, no maintenance either.
- Market research, outside your account: SmartScout.
Test it in 5 minutes
- 1. Start a Nova trial. 14 days, no card.
- 2. Connect Seller Central with Amazon OAuth.
- 3. Paste one connector URL into Claude, ChatGPT, Gemini or Cursor.
- 4. Ask this, word for word:Which SKUs lost the most net profit versus last month, and why?
You get rows: SKU, profit change, and the fee, price or ad-spend line that moved it.
Start the free trialRanked by criterion, not overall
One overall ranking on a vendor's own page is worth nothing, so here is the ranking split by the thing you are buying for. Nova wins four rows. It loses two, and it loses them cleanly.
Deepest profit modelling
Net profit reconciled to the cent at SKU level across 40+ Amazon fee types, with your own COGS, FBM cost and VAT categories included.
Closest alternative: DataDoe models SKU profit but on daily tables and without your landed cost.
Search Query Performance
SQP exposed through the assistant, de-duplicated, with like-for-like period comparisons. Almost no other Amazon MCP exposes SQP at all.
Closest alternative: Helium 10 covers keyword and reverse-ASIN research, which is a different question.
Marketplace coverage and history
23 marketplaces in a single call, currency-normalised, with 24 months of backfilled history.
Closest alternative: Fluvi publishes broader marketplace coverage but not the history depth.
Agencies and multi-account
Several Seller Central accounts under one connection, one currency, one model, so a client question is one call rather than one call per account.
Closest alternative: Two Minute Reports puts Amazon beside other channels, but without the account economics.
Campaign write actions available today
Amazon's own server, free, generally reachable with Ads API credentials, and it creates campaigns and moves bids today. Nova write mode is still in beta.
Closest alternative: PPC Assist and DataDoe also write, both third-party, both paid.
Free and self-hosted
No licence, no vendor, full control. You get raw endpoints and you maintain them.
Closest alternative: Amazon Ads MCP is also free, but scoped to advertising only.
Every server, entry by entry
Nova's entry is verified first-hand by introspecting the live server. Everything else comes from vendor documentation, the official MCP Registry or public repository metadata, and each entry says which. Nothing here was tested on a live competitor account.
Nova
The data + action MCP for Amazon sellers
Profit you cannot get elsewhere. Net profit per SKU after every Amazon deduction, reconciled to the cent across 40+fee types, with your own COGS and FBM costs inside the number. Every other server on this list either stops at account level or stops at what Amazon publishes.
Search Query Performance in the chat. De-duplicated, with like-for-like period comparisons. Ask which keyword lost share and get the answer, not a report to download.
Write actions with profit context, in beta. Amazon's server can move a bid but does not know your landed cost, so it cannot tell a profitable ACoS from an unprofitable one. A profit tool that cannot act leaves you doing the work by hand. Nova is building the combination, and write mode is in beta today, not shipped.
Your cost data, maintained by talking. COGS per SKU, FBM rates and VAT categories can be set and corrected through the MCP itself, in conversation. That is live now, and no competitor on this list offers it.
One call, not eight. Pre-aggregated, structured tables rather than raw payloads, so a question costs one low-token call instead of paging through orders, settlements and fees and joining them in the model.
The widest modeled Amazon layer on the market: SKU-level profit after every fee, PPC, search query performance, inventory, inbound and 3PL, listing health and BSR, joined in one model, plus live Vendor Central (1P) connections. Write mode is in beta.
- •Net profit per SKU after every Amazon fee, plus your COGS and FBM costs
- •PPC spend, ACoS, TACoS and search terms at product level
- •Search Query Performance, de-duplicated, with like-for-like comparisons
- •Inventory, days of cover, inbound shipments and 3PL
- •Listing health, Buy Box state and BSR on your own ASINs
- •23 marketplaces, 24 months of history, refreshed up to every 30 minutes on money metrics
Best for: Brands and agencies that want an assistant to answer any Amazon question, from which SKU is losing money after fees to which keyword is worth the bid.
Weakness: Write mode is in beta rather than generally available.

Give your AI assistant every Amazon number
Nova MCP exposes SKU-level profit after fees, PPC and search terms, inventory, inbound and listing health across 23 marketplaces, and write mode (in beta) lets the assistant act on them. Connect Seller Central once.
What an MCP server does, in one paragraph
The Model Context Protocol is an open standard for connecting AI assistants to external systems. A server publishes a set of tools with typed inputs; the assistant reads the tool list, decides which one answers the question in front of it, calls it, and reasons on what comes back. The specification and a reference server collection are public on the protocol documentation site and in the modelcontextprotocol/servers repository, which is where most of the ecosystem started.
The important consequence for operators: the assistant is no longer limited by what you remembered to paste into the chat. It is limited by what the server exposes, and by how usable that data is once it arrives.
Data servers, action servers, and the one that does both
Every ecommerce MCP server falls into one of two jobs, and confusing them is the most common reason a first connection disappoints.
- Data servers read a modeled view of your business: revenue, margin, fees, stock cover, keyword efficiency. This is where the decision gets made.
- Action servers change something: create a campaign, adjust a bid, confirm a shipment. Amazon's Ads MCP server is the reference example.
Until now you needed one of each. Nova closes that gap: it is the widest data server on the market, and write mode, in beta today, turns the same connection into an action server. That is the trajectory that puts an Amazon business on autopilot: one assistant, one connection, answers and execution on the strength of the data model underneath.
Multi-channel brands often add a platform server too, such as the storefront server documented in the Shopify developer docs, which is why two or three connections enabled at once is normal.

The gap nobody fills by accident
Is there an official Amazon SP-API MCP server?
No. Amazon publishes an official MCP server for advertising, in open beta since February 2026, and it can create campaigns and move bids. There is no first-party server for the Selling Partner API, so every profit, fee, inventory and listing answer available through MCP today comes from a third party or from a wrapper you host yourself.
That is the whole shape of this market. The official server can act but cannot see your margin. The third-party servers can see, and only some can act.
Free and open source Amazon seller MCP servers
There are free options, and they are honest about what they are. Community repositories wrap Selling Partner API endpoints as MCP tools. The most visible one, mattcoatsworth/AmazonSeller-mcp-server, had 43 stars and was last pushed in April 2025 when we checked its GitHub metadata on 7 September 2026. Two Minute Reports also publishes a Seller Central repository, created April 2026.
What you get: raw endpoints, no licence fee, full control. What you carry: SP-API credentials, rate limits, breaking changes, and the fact that none of these model profit. An unmaintained wrapper is a fine weekend project and a poor foundation for a decision about restocking.
Amazon's Ads MCP server is the other genuinely free option, and it is maintained by Amazon. It is scoped to advertising.
Ecommerce beyond Amazon
Multi-channel brands usually add a platform server next to the Amazon one. Two or three connections enabled at once is normal, and they answer different questions: the platform server knows the storefront, the Amazon server knows the marketplace economics. Each of these was checked against its own documentation.
Storefront MCP
ShopifyCatalog search, cart operations and storefront context for agents shopping a Shopify store.
Gap: Storefront-facing. Not a merchant finance or margin layer.
Stripe MCP
StripePayments objects: customers, invoices, subscriptions, balance and payment intents, plus documentation search.
Gap: Payments only. No view of marketplace fees or fulfilment cost.
PayPal MCP
PayPalInvoices, orders, subscriptions, disputes and transaction reporting on the PayPal account.
Gap: One payment method's view of revenue, not the whole store.
Klaviyo MCP
KlaviyoProfiles, lists and segments, campaigns, flows and campaign performance metrics.
Gap: Marketing engagement, not order economics.
AWS MCP servers
AWS LabsA large open-source collection covering AWS services: documentation, cost analysis, databases, infrastructure.
Gap: Infrastructure, not commerce. Nothing here reads a Seller Central account.
Coverage is table stakes. Correct answers are not
Some Amazon figures must never be summed. Search query volume repeats on every parent ASIN that ranks on it. FBA quantities share pools across SKUs. A good server refuses those additions in the tool contract rather than trusting the model to know. Four guards built into Nova:
Search volume, de-duplicated
Naively summing search query rows overstates demand by roughly 2.4x. Nova returns the de-duplicated total.
Like-for-like comparisons
Year on year is computed only over keywords present in both periods. Raw totals can read +34% where the truth is -3%.
Calendars aligned
Amazon search weeks start Sunday, ad weeks start Monday. Nova states the exact days each period covers.
Pools and namespaces separated
Shared FBA pools are flagged, and product, ads and search metrics stay in separate universes so nothing cross-sums.
How to judge a server before you connect it
Five questions separate a server you still use in three months from one you disable after a week.
Does it join the data, or hand over silos?
Profit is orders minus every Amazon fee minus your landed cost minus ad spend. A server that returns each of those from a different endpoint pushes the join into the model, which is exactly where it goes wrong.
Does it stop the assistant computing a wrong number?
Some Amazon figures must never be summed. Search query volume repeats on every parent ASIN that ranks on it. FBA quantities share pools across SKUs. A good server refuses those additions in the tool contract rather than trusting the model to know.
How fresh is the answer?
Daily tables are fine for a monthly review and useless for a stock-out call at 4pm. Ask what the refresh interval is on money metrics specifically, not on the dataset as a whole.
Read, or read and write?
A read server informs the decision. An action server executes it. They are not competing products, and most people running assistants daily end up with one of each.
Auth and auditability
OAuth with revocable per-account credentials is the baseline. Beyond that, ask whether calls are logged with the reason they were made. Anyone handling client data will be asked this eventually.
Cost is the one people underestimate. A thin API wrapper often needs eight to twenty calls, because the assistant has to page through orders, then settlements, then fees, then join them itself. Amazon also enforces per-operation rate limits, documented in the SP-API usage plans reference, so those calls get slower exactly when the date range gets interesting.
What each category of ecommerce MCP server actually covers
| Server type | Typical scope | Read or write | Best for |
|---|---|---|---|
| Nova (data + action) | P&L, fees, PPC, search terms, SQP, inventory, inbound and 3PL, listings, BSR | Read, write in beta | Profit, pricing and inventory decisions, then execution |
| Amazon Ads MCP (first-party) | Sponsored ads campaigns, bids, reporting | Both | Executing ad changes from chat |
| Shopify MCP (first-party) | Storefront catalog, cart, store data | Read plus commerce actions | Shopify-native storefront workflows |
| Research servers | Brands, sellers, categories, competitor keywords | Read | Sourcing and market mapping |
| Community SP-API wrappers | Raw Selling Partner API endpoints | Read, sometimes write | Developer experiments |
Which should you connect?
Find yourself in the left column. Where a competitor is the right answer, it says so.
Private label brand, 7 to 8 figures
Nova, the data + action MCP
The question you ask most is which product is actually making money after fees, and then what to do about it. Nova answers it from one joined data model, and write mode, in beta, lets the assistant carry out the decision too.
Agency or aggregator, many client accounts
Nova
One connection covers every client account, scoped per client, with each call recorded alongside the reason it was made. That is the part a client will ask about.
Wholesale or online arbitrage
SmartScout, plus Nova once your own catalogue matters
Your first question is about the market, not your P&L. Use a research server for sourcing, and add a data server when margin per SKU starts driving decisions.
Vendor Central (1P)
DataDoe
DataDoe covers Vendor Central today. Nova Vendor Central support is live, so you can run both 1P and 3P in one workspace.
Ads-only operator
Amazon Ads MCP, plus Nova as the guard rail
An ads-only agent cannot see margin, stock cover or Buy Box state, so it will bid confidently on a SKU that loses money or is about to run out. The read layer is what stops that.
Our take
Which MCP server should you connect first?
Connect the server that carries your own numbers and can act on them. Nova reads the whole business, and write mode, in beta, lets the assistant execute as well.
Best fit if
- •Sellers who make daily pricing, restock or ad-budget calls
- •Agencies reporting on several accounts at once
- •Teams already using Claude, ChatGPT or Gemini for analysis
Skip if
- •Developers who only need raw endpoint access for a build
- •Operators whose only question is campaign execution, where the Ads MCP alone is enough
Where this goes next
Two things are changing fast. First, client support is converging: remote MCP servers now work across the major assistants, so vendors ship one endpoint rather than one integration per model. Second, the competition is moving from "do you have an MCP" to "how good is your data model", because every vendor can expose tools and very few can expose a reconciled P&L. Read and write are converging too: the servers that win are the ones that answer the question and then carry out the decision.
For sellers, that is the useful filter. The assistant is a commodity. The data underneath it is not. Related reading: Amazon Ads MCP compared with Nova MCP, Amazon MCP for agencies and the Claude setup walkthrough.

Method and changelog, last verified 30 August 2026
Page last updated 7 September 2026. Nova's entry is verified first-hand by introspecting the live server. Other entries come from vendor documentation, the official MCP Registry and public repository metadata, never from testing a competitor account. Where a vendor publishes no figure, the cell says "not published" rather than an estimate. Reviewed quarterly, and corrections from vendors are welcome.
- 30 August 2026: First publication. All vendors reviewed, Nova verified first-hand by introspecting the live server. Nova rows reflect inbound and 3PL coverage, with write mode in beta and Vendor Central (1P) live. Sellerboard listed as reported only.
- 7 September 2026: Re-targeted the page on Amazon seller MCP servers. Added AgentCentral, PPC Assist, Seller Labs, Zapier MCP, Two Minute Reports and the open source SP-API repositories, each from vendor documentation, the official MCP Registry or GitHub metadata rather than first-hand testing. Replaced the single overall ranking with a ranking by criterion, in which Nova loses the write-actions row to Amazon Ads MCP and the free row to the open source servers. SellerPPC was checked and left out: no MCP offering could be verified. Merged the Nova-specific comparison article into this page and redirected it.
