You decide what it may do

When you connect, the app opens a SellerMagnet page. You sign in there and choose:

Permissions
Reading is always on. Bids, pausing, budgets, keywords, campaign settings and recommendations are separate switches.
Amazon Ads profiles
Only the profiles you tick. The app never sees your other projects.
How changes are made
Apply directly within your limits, or have bid, budget and pause changes wait in your Approval Center until you approve them.
Safety limits
By default at most 50% bid change and 50% budget change per action, 300 changes a day and 50 items per request. You set your own values on the same page.

What happens to every change

Your assistant cannot reach Amazon past SellerMagnet. Each change it asks for goes through the same steps:

  1. Preview

    Every change tool has a dry run, and the server asks your assistant to show you the preview before it applies anything.

  2. Checks

    SellerMagnet confirms the ids belong to your profiles and applies your limits and PPC guardrails: protected keywords, maximum bid steps, and raises only with performance evidence.

  3. Live or waiting

    In direct mode the change goes to Amazon. In approval mode, bid, budget and pause changes wait in your Approval Center until you approve them, and anything that cannot wait there is refused.

  4. Logged

    The change appears in your PPC Activity Log, marked as made by an AI assistant, next to your own changes.

  5. Reversible

    Undo bid, budget and state changes for 24 hours. Revoke the app in Settings and it loses access at once.

Security, in plain terms

Sign-in
OAuth 2.1 with PKCE. You sign in on SellerMagnet and the app only receives a token.
Access
One project and the Amazon Ads profiles you ticked. Every id the app sends is checked against them.
Tokens
Access tokens last 60 minutes. Refresh tokens last 30 days and change on every use; reusing an old one ends the connection.
Expiry
A connection ends after 90 days, or the moment you revoke it.
Rate limits
120 calls and 30 write calls per minute for each connection.
Records
Every tool call the server runs is audited. Every change is in your PPC Activity Log.
Amazon credentials
Stay with SellerMagnet. The AI app never receives them.
Your data
What your assistant reads is sent to the AI provider you use, under that provider's terms.

Questions sellers ask

What is an MCP server?
MCP (Model Context Protocol) is the open standard AI apps use to call outside tools. The SellerMagnet MCP server gives your assistant 27 PPC tools, 17 that read data and 10 that make changes, all limited to your own account.
How is this different from uploading reports to ChatGPT or Claude?
An uploaded report is a one-off snapshot your assistant can only read. Through the SellerMagnet Amazon Ads MCP server it reads the data SellerMagnet keeps in sync with your Amazon Ads account whenever you ask, and it can make changes within your permissions and limits, each one checked and logged.
Can Claude or ChatGPT manage my Amazon PPC?
Yes, through this server. Connect it once, then ask in plain language: find wasted spend, compare campaigns, lower bids, add negatives. Changes respect your limits and your PPC guardrails, and you can require your approval for every one.
Can the AI break my campaigns?
It can only do what you allowed, inside the limits you set. Bid changes go through the same checks as SellerMagnet's own automation, every change is logged, and in approval mode nothing goes live without you.
Does it cost extra?
No. It is included with the PPC Manager. Your assistant runs in your own AI app, so it uses no SellerMagnet credits.
Which AI apps work with it?
Any app that supports remote MCP servers with OAuth sign-in: Claude on the web, in the desktop app and in Claude Code, ChatGPT, Cursor, VS Code and others.
Can it create or delete campaigns?
Not yet. Today it reads everything, changes bids, budgets, states and bidding settings, adds keywords and negatives, harvests search terms and handles recommendations. Creating and archiving campaigns come next.
Which marketplaces are covered?
Every Amazon Ads profile connected to your SellerMagnet project. Data stays in each marketplace's currency, and the money limits you set in US dollars are converted to it.
How do I disconnect an app?
Open Settings > AI connections and press Revoke. The app loses access at once and its tokens stop working.
