How Sell Through runs client analysis inside Claude

Josh Grillo swapped once-a-day Data Studio dashboards for Nova, and asks Claude for the answer instead of rebuilding the report.

Runs Nova in

Claude, through the Nova MCP connector

Sell Through is a boutique US retail media agency that manages Amazon accounts to a TACoS target set against the brand's real margin. Before Nova, client reporting came out of Data Studio dashboards refreshed once a day, and the numbers could only be read at account level. Josh tried other Amazon MCP servers first: they returned raw Amazon data, so his team spent more time checking figures than using them.

Before Nova, after Nova

Before Nova

Dashboards pulled once a day, so the numbers in a client call were often already out of date.

Reporting stopped at account level, with no product-level TACoS or ACoS to act on.

Other Amazon MCPs returned raw Amazon data that the team had to verify before trusting it.

After Nova

Data refreshed through the day, and answers pulled live in Claude while the question is still open.

Product-level advertising and profit metrics, so spend decisions happen per ASIN instead of per account.

Nova returns modelled, reconciled metrics, so the answer is the deliverable rather than the starting point.

In his words

"One of the blessings we've had with Nova is the MCP they offer."

"The Nova team has built something truly special. The days of clunky Looker Studio dashboards are over. They are communicative and collaborative, and work hard to make the platform as helpful as possible for their users."

Questions about this setup

How Sell Through runs Nova, and how to do the same.

Data Studio dashboards that were pulled once a day. Josh says in the video that the numbers were frequently out of date by the time they were used, and that reporting could only be read at account level rather than per product.
They returned raw Amazon data. Josh's team spent more time checking whether the numbers were right than using them, so the connector added work instead of removing it.
It exposes Nova's modelled Amazon metrics, 500+ of them across 21 marketplaces, to Claude, ChatGPT or Gemini. The assistant asks Nova for a metric and gets a reconciled figure back, rather than pulling raw reports it has to interpret.
Yes. Nova supports multiple Seller Central and Vendor Central connections with account switching and consolidated reporting, which is how Sell Through runs it. Extra Seller Central accounts start at $29 per month.
Every plan includes a 14-day free trial with no credit card, and the MCP connector is available inside Nova once your Amazon account is connected.
