Amazon's plugin and Nova, side by side

Amazon does not know your supplier, freight, duty or VAT costs, so its plugin cannot return profit after them.

Example answers. Figures shown are illustrative, the shape of the response is not.

What you can ask today

  • Ask for net profit by SKU, brand, marketplace or tag over any date range
  • Rank the biggest movers of the week and get the signals behind one of them
  • Pull Sponsored Products, Brands and Display at campaign, ad group and keyword grain
  • Read the customer search terms and Search Query Performance behind a listing
  • Check FBA stock cover, and which SKUs run out inside 21 days at the current rate
  • See suppressed listings, buy box state and Best Seller Rank on your own ASINs

What it will not do

  • 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.
  • Access another seller's account. Credentials are per account and revocable.
  • Read data Amazon does not expose to the Selling Partner and Advertising APIs.
  • Replace Seller Central itself. Case management and account settings stay there.

Why this MCP and not another one

Coverage

SP-API, Ads, Search Query Performance, search terms, inventory, listing health and BSR, across 23 marketplaces. Vendor Central (1P) is live.

Freshness

Orders and units reach Nova within seconds of the sale, with sales estimated until Amazon confirms the exact amounts. Ad spend refreshes every two hours, search term data three times a day, Amazon finance transactions hourly, and the remaining reports daily.

Speed and tokens

Structured, pre-aggregated tables instead of raw dumps, so one question is usually one low-token call rather than several round trips.

Your costs, not just Amazon's

COGS per SKU, FBM cost, your own tags and 24 months of backfilled history, reconciled at 99.9% accuracy across 370 transaction lines.

The full row-by-row comparison lives on the Nova MCP page.

Connecting Seller Central to an assistant raises three fair questions.

Answers in seconds

Pre-aggregated responses, ranked server side, light on tokens.

Revocable

Per-account credentials you can pull back at any time.

Minutes, not a project
