Copy-paste prompt
You have read access to my Amazon Ads and sales data. Don't change anything without my approval. 1. List my current campaigns and the products each one covers. Flag any campaign that mixes different product formats. 2. Propose a structure with one campaign per product format, each with its own keyword list pulled from search terms that already convert for that format. 3. For every change you want to make (new campaign, bid, budget, negative), tell me what and why, and wait for my yes. 4. Each week, report spend, CPC, sales and units by product format against the week before.

What they did
A founder of an 85-person brand fired his ad agency in December 2025 and took the ads back himself, with Claude connected to his Amazon data through Seller Labs' MCP server. The agency had run 12 campaigns; he runs about 40, each built around one product format with its own keywords. At first the AI made changes on its own and he stopped it; now it tells him what it wants to do and why, and he approves every change.
How it went
Per the author, four months later he was saving about $75,000 a month: $15,000 from the agency fee and about $60,000 in ad spend, with daily spend down from $5,800 to $3,800. Cost per click on some ads dropped from $2.50 to $0.90, sales were up by a third, and one product went from 400-500 units a month to 1,400.

Worth knowing
This is a secondhand account from Nhan Dinh of Seller Labs, whose company makes the MCP server the founder uses. The founder's split, in his words: 'I feed Claude 10%, it does 80%, and then I watch the last 10%.'
