Claude MCP for Amazon Sellers - Live Data in One Query 2026
Claude MCP finally lets AI answer real questions about your Amazon business. This guide covers what MCP is, what the Amazon MCP landscape looks like in mid-2026, and how to connect Claude to your live Nova data in an afternoon.
Nova MCP for Claude is live. Existing customers connect it in a single click from the integrations panel.
Amazon's Selling Partner plugin for Claude is in beta for US stores since 23 September 2026, with a waitlist. It reads listings, inventory and sales, and has no view of your cost of goods, freight, duties or VAT. How it compares with Nova.
Amazon's Ads MCP Server remains in open beta. It covers the ads silo only, so it complements Nova rather than replacing it.
This guide walks through what Claude MCP is, what Nova MCP exposes, and how to wire the two together on your own data.
Claude MCP finally makes it easy to ask Claude real questions about your Amazon business. But the answer is only as good as the data model Claude reads. This guide covers what MCP is, what Nova MCP exposes, and how to point Claude at your live seller data in an afternoon.
The custom connector links Claude to Nova for questions about your Amazon data.
What Claude MCP actually is
Model Context Protocol (MCP) is the open standard Anthropic published in late 2024 to let AI assistants call external tools through a structured interface. Instead of pasting CSVs into a chat, you run (or connect to) an MCP server that exposes tools. Claude decides which tools to call, calls them, and reasons on the returned data inside the same conversation.
For Amazon sellers, the important thing is that MCP is a data protocol, not a data model. Anyone can publish a server; the quality of the answers Claude gives depends on what that server actually joins together for it.
The Amazon MCP landscape in mid-2026
Three groups of servers matter today:
Amazon Ads MCP Server - open beta, covers Sponsored Products, Brands and Display metrics from Amazon's ad accounts. Announcement at advertising.amazon.com. Useful, but ads-only.
Community SP-API wrappers - GitHub projects that thinly wrap Selling Partner API endpoints. They give Claude a socket to SP-API but no data model: it still has to reconcile fees, joins and rate limits inside the prompt.
Nova MCP - a seller-grade MCP server that exposes Nova's joined Amazon data model (orders, 40+ fee types, FBA inventory, PPC at product level, organic) as tools Claude can call in one turn.
Pick a server based on the question you want Claude to answer. If it is "what happened in my ads this week", Amazon's own MCP is fine. If it is "which 10 SKUs killed my margin across DE and UK last week and why", you need a seller-grade model, not a raw API socket.
What Nova MCP exposes to Claude
Nova MCP is a Claude connector on top of the same Nova data model that powers the dashboard. Everything in the model is joined at the SKU and marketplace grain, refreshed hourly, and covers all 23 Amazon marketplaces.
Concretely, Claude can query:
Reconciled SKU profit across 40+ Amazon fee types
FBA inventory, inbound and days of cover per ASIN
Sponsored Products, Brands and Display spend at the product level
Organic share, Buy Box, Subscribe & Save, BSR on your own ASINs
Settlement-grade P&L per marketplace and per date range
Nova MCP reads by default. Listing edits are available only when a workspace owner turns them on, and every edit is previewed and confirmed before it reaches Amazon. Prices and stock levels are never changed. Credentials are per account and revocable at any time from your Nova settings.
Connecting Claude to Nova MCP
The full walkthrough with screenshots lives in the connect-Claude tutorial:
Step by step
Connect Claude to Nova MCP
Add Nova MCP to Claude Desktop, Claude Code, or any MCP-capable client. Five minutes, no SP-API plumbing.
Sign in to Nova and connect Seller Central and Ads accounts if you have not already.
In Nova, open the MCP panel and generate a per-account credential for Claude.
Add the endpoint to Claude's MCP settings. Save.
Ask Claude a real question. The first working answer usually lands inside 24 hours.
Prompts that work well on day one
These are the prompts our team runs when we onboard a new account. They exercise the model across profit, inventory and ads without needing you to know any SQL.
A connected Claude conversation can pair an analysis with an event to revisit.
"Rank the 10 SKUs that lost the most contribution margin in the last 30 days across all marketplaces. For each, cite the top driver: fees, refunds, or ad spend."
"Draft a weekly P&L brief with the 5 biggest revenue and profit swings by marketplace, with root cause per row."
"Which ASINs will stock out in the next 21 days? Return days of cover and recommended reorder quantity."
"Which Sponsored Products campaigns spent above the break-even ACoS last week? Show ACoS, spend, and sales share."
"Compare DE and UK contribution margin this quarter vs last. Highlight the SKUs responsible for the delta."
The point is not the prompt list; it is that Claude answers each of these in one turn because Nova already joined the underlying tables. Feed the same prompt to a raw SP-API server and you will burn 8 to 20 tool calls chasing pagination and reconciliation.
From Q&A to agents
Once Claude is answering ad-hoc questions well, the natural next step is to turn the best prompts into repeatable agents. Nova customers ship three patterns most often:
Profit Watchdog - a daily Claude run that flags any SKU whose contribution margin dropped more than a threshold and posts the summary to Slack.
Restock Copilot - a weekly run that returns the reorder list with days of cover and lead-time buffer.
Ad Spend Auditor - a run after each ad-spend batch that names the campaigns above break-even ACoS with the exact reason.
None of these need custom code. They are prompts scheduled against a Claude client that has Nova MCP wired in.
Where Nova MCP stops
Two boundaries remain:
It does not change campaigns, bids, prices or stock levels. Listing edits require a workspace owner to enable them, and every change is previewed and confirmed before it reaches Amazon.
It is not a keyword-research surface. For SEO or keyword scouting, use a research tool that crawls the SERP. Nova is about your own numbers, not the wider marketplace.
Everything else that reads from your Amazon business - profit, ads, inventory, organic on your own ASINs, cross-marketplace briefings - is what Nova MCP is built for.

Find answers to common questions about our platform
Model Context Protocol (MCP) is Anthropic's open standard for connecting Claude to external data and tools. A Claude MCP server exposes a set of read or action tools that Claude can call inside a conversation. For Amazon sellers, that means Claude can query live SP-API and Ads data through a single MCP server instead of asking you to paste CSVs.
Yes, since 23 September 2026. Amazon's Selling Partner plugin for Claude is in beta for US stores, with a waitlist and a Professional selling plan required, and Amazon says it pulls listings, inventory levels and sales analytics. Amazon also ships an Ads MCP Server for advertising. Neither holds your cost side (cost of goods, freight, duties, VAT), which is where Nova MCP differs: it exposes a pre-modeled seller data model (orders, 40+ fee types, FBA inventory, PPC at the product level, organic) as MCP tools Claude can call.
Profit questions (which SKUs lost margin last week), inventory questions (which ASINs risk stockout in 21 days), PPC questions (which campaigns spent above break-even ACoS), and cross-marketplace briefings (P&L delta across the 23 marketplaces). Claude answers in one turn because the data is already joined in Nova.
Nova MCP reads by default. Listing edits are available only when a workspace owner turns them on, and every edit is previewed and confirmed before it reaches Amazon. Prices and stock levels are never changed, and Nova does not change campaigns, budgets or bids.
Any Claude client that supports MCP works: Claude Desktop, Claude Code, or another MCP-capable client. Nova provides the endpoint and the credentials. You bring your own Claude account.
A CSV export is stale the second you download it and stops at whatever slice you pulled. Nova MCP gives Claude live access to 371 metrics across 23 marketplaces, with orders and units arriving in real time, joined at the SKU level. No re-exports, no reconciliation prompts, no missing fees.
All 23 Amazon marketplaces Nova supports. Claude can answer consolidated or per-marketplace questions from the same model.
Most teams connect Seller Central to Nova, point Claude at the Nova MCP endpoint, and ship their first working prompt within 24 hours. The step-by-step is in our Connect Claude walkthrough.
