Nova MCP Server Guide 2026: Connect Your Amazon Seller Data to Claude, ChatGPT, and Gemini

Nova MCP is a remote Model Context Protocol server that lets Claude, ChatGPT, and Gemini query your live Amazon profit, PPC, inventory, and listing data. It is included in every Nova plan from $29 a month, takes about a minute to connect, and returns reconciled numbers with fees and returns already applied. It is read-only, so nothing in Seller Central or the Ads console changes.

What that buys you: 520 metrics across 21 marketplaces, refreshed hourly, answered in one call instead of an export, a pivot table, and fifteen minutes.

• Best for: sellers and agencies who already work in Claude or ChatGPT and want real numbers in the conversation.
• Not for: sellers who want the assistant to change bids or edit listings. Nova MCP reads, it never writes.
• Cost: included in the $29 Sellers & Brand Owners plan, plus a paid Claude plan for custom connectors.
• Trial: Nova's 14-day trial, no card, covers MCP access.

Key Takeaways

Nova MCP is the profit-first Amazon connector. Amazon's own MCP server covers the ads account and Helium 10's covers research. Nova's exposes the reconciled P&L, keyword-level PPC spend, inventory cover, BSR, and listing health. Those are the numbers that decide whether a sale made money. Fourteen tools, one server URL, and a 32-prompt library get you started.

• Fourteen tools exposing 520 data points across 21 Amazon marketplaces.
• Hourly refresh, with money metrics updated every 30 minutes and 24 months of history.
• Works with Claude Desktop, Claude Code, claude.ai, ChatGPT connectors and custom GPTs, MCP-capable Gemini clients, and Cursor.
• Setup is four steps in Claude and needs no engineering.
• Included in the $29 Nova plan; read-only by design.

What Is Nova MCP and How Does It Work?

Nova MCP is the bridge between your AI assistant and Nova's data model. Nova pulls your account through the Amazon Selling Partner API and the Amazon Advertising API. It reconciles 370 transaction lines into 154 P&L lines and stores 24 months of history. The MCP server exposes that model to any assistant that speaks the protocol.

Here is what happens when you ask a question:

1. You ask in plain English, for example which SKUs lost the most net profit last week.
2. The assistant picks the matching Nova tool, such as the movers query, and sends one structured request.
3. Nova ranks and aggregates the answer on its side, so the assistant receives a small table rather than a raw export.
4. The assistant explains the result and can chain a second tool, such as the movement explainer, to show why.

That last step is the useful part. A dashboard shows you a number. A chained MCP call shows the number, the driver behind it, and the search terms that caused it, in one reply.

What Can Your Assistant Query Through Nova MCP?

Nova documents 14 tools, and you never call them by name. You ask a question, the assistant selects the tool, and the ranking happens on Nova's servers. The tools split into three jobs: profit and movement, advertising and demand, and inventory and listings. Three setup helpers list your accounts, metrics, and tags.

Profit and Movement

The profit tools answer what you made, what changed, and why it changed. They read the same reconciled P&L that powers the Nova app. Fees, refunds, reimbursements, and COGS are already netted off before the assistant sees a number. Four tools cover this side of the model.

• Metrics query: net profit by brand, marketplace, or tag for any period against any comparison period.
• Movers: the 10 SKUs that gained or lost the most net profit last week.
• Movement explainer: why one ASIN dropped 30% in profit, split into ad spend, conversion rate, and Buy Box share.
• Cost inputs: which SKUs are missing COGS, so their margin is overstated.

Advertising and Demand

The advertising tools connect spend to the queries behind it and to your share of the funnel. They read campaigns, keywords, and match types from the Ads API, then join them to profit at the SKU level. Amazon's own reporting never makes that join. Four tools cover this side.

• Advertising query: keywords that spent over $100 last month with zero attributed sales.
• Search terms: customer search terms that burned spend without a single order.
• Search Query Performance: where you lose share between click and purchase on your top queries.
• BSR: how Best Sellers Rank moved on an ASIN since a price change, per marketplace and per day.

Inventory, Listings, and Setup

The operational tools cover the problems that quietly cap revenue. Inventory cover is calculated from weighted daily demand. Listing health is the same 12-issue scanner that ranks suppressed listings and lost Buy Boxes by revenue at risk. Three setup helpers let the assistant discover what your account contains.

• Inventory query: ASINs that run out of stock inside 21 days at the current sales rate.
• Listing health: suppressed, hidden, hijacked, or undercut listings, ranked by the sales behind them.
• Accounts, metrics, and tags: the helpers that tell the assistant which Seller Central accounts, metric keys, and custom tags exist, so agencies can scope a question to one client.

Which AI Assistants Work With Nova MCP?

Nova MCP is a remote server with one URL, so any MCP-capable client can use it. Nova documents Claude Desktop, Claude Code, and claude.ai, ChatGPT through connectors and custom GPTs, Gemini through MCP-capable clients, and Cursor. The prompts in Nova's library are written for Claude, but the numbers come from your account, not from the model.

• Claude: add the server as a custom connector in Settings. A paid Claude plan is required for custom connectors.
• ChatGPT: add it through connectors, or build a custom GPT around it.
• Gemini and Cursor: paste the same server URL into the client's MCP or connectors settings.

How to Set Up Nova MCP in Claude

Setup takes four steps and about a minute once your Nova account has completed its first hourly sync. If you are not on Nova yet, start the 14-day trial and connect Seller Central and Amazon Ads with read-only access. Wait for that first sync before adding the connector.

1. Open Claude, go to Settings, then Connectors. This works in the desktop app and on claude.ai.
2. Click Add, then Add custom connector. If the option is missing, check that you are on a paid Claude plan.
3. Name the connector Nova and paste the server URL: https://mcp.novadata.io/api/mcp. Nova says no authentication is required in the current beta.
4. Toggle Nova on, open a new conversation, and ask a question about your live Amazon business.

The same URL works in ChatGPT, Gemini, and Cursor. Add it in that assistant's connectors settings instead of Claude's.

Prompts to Run First

Nova publishes a library of 32 prompts in seven groups: routines, profit, Amazon PPC, keywords, inventory, listing health, and diagnostics. Three of them are marked as verified against live accounts. The routines are the ones worth trying first. Each one chains four or five tools into a single answer, which is the thing a dashboard cannot do.

Nova says the Monday briefing replaces a 40-minute routine. Agencies get a second routine prompt that builds a weekly client report scoped to one account, which is where the accounts helper tool earns its place.

Nova MCP vs Helium 10 MCP vs Amazon Ads MCP

The three MCP servers an Amazon seller can connect today cover different jobs, and most operators end up enabling two of them. Amazon's server moves your ads, Helium 10's answers research questions, and Nova's answers profit questions. The table below shows where each one starts and stops.

Research-first sellers will get more from the Helium 10 MCP guide, which covers keyword and competitor questions on the Diamond plan. Sellers who want to know whether an ad-efficient SKU is profitable need Nova's cost side, because ACoS is a revenue ratio and two SKUs at the same 28% ACoS can sit on opposite sides of break-even. Data Dive answers the MCP question differently, which I cover in the Data Dive MCP page.

How Much Does Nova MCP Cost?

Nova MCP costs nothing on top of a Nova subscription. The Sellers & Brand Owners plan lists MCP for AI assistants as an included feature from $29 a month per Seller Central account. The 14-day trial covers it with no card. The only other cost is on the assistant side, because Claude limits custom connectors to paid plans.

• Nova side: included from $29/mo, custom pricing for agencies with unlimited accounts.
• Claude side: a paid plan for custom connectors; the free tier cannot add one.
• ChatGPT and Gemini: whatever plan your connector or custom GPT requires.
• Call limits: Nova publishes none, unlike Helium 10's 1,000 calls a month.

What Are the Limitations of Nova MCP?

Nova MCP is strong at answering questions and does not try to act on them. It cannot change a bid, pause a campaign, edit a listing, or place a purchase order. The data is near real time rather than live. The answers are only as good as the COGS you upload, and the connector is still labeled a beta.

• Read-only: analysis only. Changes stay with your team or with Amazon's own Ads MCP.
• Hourly, not instant: the P&L refreshes hourly and money metrics every 30 minutes, so a sale from two minutes ago is not in the answer yet.
• Garbage in, garbage out: SKUs without COGS show overstated margin. The cost inputs tool exists to catch that.
• Beta: Nova describes the current connector as a beta with no authentication step, so expect the setup to change.
• Paid assistant plans: Claude's free tier cannot add custom connectors.
• Amazon only: other e-commerce channels are listed as coming soon.

Is Nova MCP Worth Using?

Yes, if you already run your week in Claude or ChatGPT and your Amazon business has real cost complexity. The connector turns a Monday of logins and exports into one question. It is the only seller-data MCP server I know of that returns reconciled profit rather than raw sales. For one account and one product line, the Nova app alone covers the job.

• Use it if: you manage several brands or client accounts, or you want profit context next to every ad decision.
• Skip it if: you want an assistant that changes bids, or you only need a daily profit number.

Nova is one of the tools in my best AI tools for Amazon sellers roundup for exactly this reason: the assistant integration is the feature, and the analytics platform underneath it is what makes the answers trustworthy.
