You decide what it may do

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

Areas
Tick the areas the app may read: sales, products, expenses, reimbursements, repricer, listings, Offer Watch, alerts, review requests, tags, product research and PPC.
Actions
Every kind of change is a switch of its own, per area. Nothing is ticked for you.
Safety limits
By default at most 300 changes a day, 50 items per request, 25% repricer price change per action, 50 review requests and 25 product lookups a day. You set your own values on the same page; 0 switches an action off.
Narrow or revoke later
In Settings > AI connections you can remove areas and actions from a connection or revoke it. It loses access at once.

Only your own data, always

A connection belongs to one SellerMagnet project. Everything your assistant reads or changes is checked against that project on every call.

One project
The connection sees the project you chose when connecting, never your other projects or another seller's data.
Every id checked
Order, product, repricer, claim, expense and alert ids are checked against the project before anything is read or changed. An id of another account is refused.
Your membership
If you leave the project or it is deleted, the connection stops working: at once for every area, within 30 seconds for PPC.
Same rules as the dashboard
The assistant goes through the same checks, plan limits and protections as you do in SellerMagnet.
No secrets
Amazon tokens, passwords and payment data never reach the AI app.

What happens to every change

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

  1. Preview

    Every action has a dry run, and the server asks your assistant to show you the preview first.

  2. Confirm

    What cannot be undone or costs money, like deleting, sending review requests or AI drafts, needs a second confirmation.

  3. Checks

    SellerMagnet applies your permissions, limits, plan and its own guardrails, the same ones the dashboard uses.

  4. Logged

    Every call is in Settings > AI connections > Activity, and PPC changes also in your PPC Activity Log.

  5. Reversible

    Repricer band changes and listing edits can be undone. Revoke the app 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 areas you ticked. Every id the app sends is checked against that project.
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 is audited and listed under Settings > AI connections.
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 the SellerMagnet MCP server?
A remote MCP server that connects AI apps such as Claude, ChatGPT and Cursor to your SellerMagnet account. It offers 108 tools across 12 areas, 64 that read data and 44 that make changes.
Can the assistant see other sellers' data?
No. A connection belongs to one of your projects, and every id it sends is checked against that project on every call. It never sees your other projects or anyone else's data.
Which areas can it use?
Sales and orders, products and inventory, expenses and refunds, reimbursements and fee audit, repricer, listings, Offer Watch, alerts and notifications, review requests, tags, product research and Amazon Ads (PPC). You choose which when connecting.
Can it change my repricer?
If you allow it: create, edit, start, stop and delete repricers, and raise or lower their price bands within your largest-price-change limit. Every change is previewed first, deleting needs a confirmation, and band changes can be undone.
Does it cost extra?
No. Your assistant runs in your own AI app and uses the SellerMagnet tools your plan or trial includes. Only actions that also cost in the dashboard, like AI drafts or product lookups, use your credits or allowance, inside the daily limits you set.
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 the AI do something I did not want?
Only within the areas and actions you ticked and the limits you set. Every action has a preview, irreversible or paid ones need a confirmation, and you can narrow or revoke the connection at any time.
How is this different from the PPC MCP server?
It is the same server. The PPC page explains the Amazon Ads part in detail; this page covers every area. One connection can include PPC and any other area.
How do I disconnect an app?
Open Settings > AI connections and press Revoke. The app loses access at once and its tokens stop working.

The tools your assistant works with

The MCP server works on the same data, rules and history as the SellerMagnet tools you use every day.
