Which plans include the MCP server?

Every paid plan: Scout, Hunter and Predator. There is no add-on fee.

What does it cost to use?

Reading your leads, sellers, products, eligibility and profit is free. A fresh Apex Read costs one credit, and a cached one is free. Scoring a batch costs one credit per unscored product, and it tells you the total before charging.

Can the AI touch my Seller Central account?

No. The connection can read your Arbitrage Stalker data, check eligibility, save products and manage monitors when you ask. It cannot reach your password, your billing or Seller Central.

Which AI apps work with it?

Claude on web, desktop and phone, ChatGPT, Claude Code and Cursor. Claude and ChatGPT sign in with OAuth, so there is no key to copy. Claude Code and Cursor use a connection key.

How do I disconnect it?

Open AI Connection Keys in your account and click Revoke. It stops working on the next request.

Is this the same as Amazon's Selling Partner plugin?

No. Amazon's plugin reads your own listings, inventory and sales. Arbitrage Stalker covers sourcing: what competitors are adding, what you can sell, and whether a buy makes money.

MCP server

Your sourcing data, inside Claude and ChatGPT

Arbitrage Stalker runs an MCP server, so Claude, ChatGPT, Claude Code or Cursor can read your own account: the products your tracked sellers just added, your saved leads, what your Amazon account is allowed to sell, and the profit on each deal using your prep and inbound costs. You ask in plain English. The numbers come from the same calculator behind your dashboard, not from the model's memory.

What did my sellers add today?

New products from the storefronts you track, filtered by brand, category, price or rank. Run it each morning and you only see what's new since your last run.

Can I sell these 100 ASINs?

Checks each one against your own Amazon account. Back comes BUY, APPLY with Amazon's approval link, SKIP or BAD_ASIN for a typo. It never submits an ungating request for you.

Is this worth buying at $12?

Exact profit and ROI with your saved prep and inbound costs, plus the rank and competition behind the call. Fee math runs through the app, so the AI can't guess it wrong.

Which brand can I actually sell?

Ask about a whole brand. It samples the best sellers first and tells you when the brand sits behind one approval, instead of listing hundreds of locked products.

Which tracked sellers produce?

Your store roster with 7-day and 30-day finds per seller, so you can swap out the dead slots. Add a store by pasting a seller ID or storefront link.
