How Quince MCP works
Quince MCP is a remote MCP server. Your AI app connects to it, and it connects to your Amazon accounts through Amazon's Selling Partner API and Amazon Ads API.
What you need
- A Seller Central account in a North America or Europe marketplace. To connect ads, an Amazon Ads account too.
- The account owner's login, or a user with permission to authorize apps.
- Claude, ChatGPT or another app that supports remote MCP servers.
Connect your Amazon accounts
- Sign in to Quince MCP and open Connect.
- Choose Connect Seller Central. Amazon shows its own consent page listing the access Quince MCP asks for. Approve it there.
- Choose Connect Amazon Ads and approve on Amazon's consent page, then pick the ad profiles you want available.
We never see your Amazon password. To revoke access later, disconnect in Quince MCP or remove the app in Seller Central under Apps and Services, Manage Your Apps.
Add it to Claude or ChatGPT
- In Claude, open Settings, Connectors, Add custom connector. In ChatGPT, add it as a connector in Settings.
- Paste the address
https://quincemcp.com/mcp. - Sign in to Quince MCP when the app asks. That's the only login the AI app gets.

What Claude can change
Every type of change starts switched off. You turn on the ones you want under Permissions.
| Change | How you approve it |
|---|---|
| Pause or enable keywords, targets and campaigns | One tap in the chat |
| Add negative keywords and negative product targets | One tap in the chat |
| Change bids, budgets and placement adjustments | Approval page |
| Add harvested search terms as keywords | Approval page |
| Create a Sponsored Products campaign (created paused) | Approval page |
| Change a product's price | Approval page, with a price warning and a second confirm over 20% |
| Restore earlier bids, budgets, states and prices | Approval page |
How an approval works
- Claude proposes a set of changes. Each proposal stores the current values from your account and expires after a while.
- You open the approval link on quincemcp.com, signed in as yourself, and approve or reject each change. The AI app can't open this page for you.
- Before applying, we check your account again. If a value moved since the proposal, that change is refused and Claude proposes it again.
- We apply the change through Amazon's API, read it back to confirm it landed, and log it with the before and after values.
