Sellerfy
Sellerfy + Claude · Beta

Connect Claude to your Sellerfy account.

Connect Claude to your Sellerfy account and get answers about your returns, reimbursement claims, inventory and profit in plain English, from the data Sellerfy already syncs from Amazon. Setup takes about two minutes, and Claude never sees your password. New to the connector? See what it can do.

Connect Claude

What you can ask

Claude reads your live Sellerfy data, so you can ask the questions you'd otherwise answer by opening reports.

What was my net profit last month, and what were my biggest Amazon fees?
Show me every open reimbursement claim and its Amazon case ID.
Which recovery cases are ready to file, and how much could I recover?
Which units have been stuck in testing for more than two weeks?
How many units of my best seller are at FBA right now?
Set the unit cost of SKU ABC-123 to $112.

Connect in about two minutes

You'll need a Sellerfy account and a Claude or Codex account. During the beta your Sellerfy account must be enabled for Claude. Ask us to turn it on.

Claude on the web & desktop

claude.ai and the Claude desktop app

  1. In Claude, open Settings → Connectors and choose Add custom connector.
  2. Name it Sellerfy and paste this URL:
    https://mcp.sellerfy.io
  3. Click Connect. A Sellerfy page opens: sign in with your Sellerfy email and password (or passkey).
  4. Check that it says Claude is connecting, then click Allow. You're sent back to Claude.
  5. Start a new chat and ask a question. Claude uses Sellerfy when it's relevant.

See Anthropic's help center for which Claude plans include custom connectors. On Team and Enterprise plans an admin may need to add the connector first.

Other AI apps. Sellerfy's connector uses the open Model Context Protocol (MCP) with secure sign-in. It works with Claude (web, desktop and Claude Code) and OpenAI Codex. Other assistants that support remote MCP servers with browser sign-in may also work.

What Claude can access

Only your own Sellerfy account, and only through these actions. Claude can't reach billing, team members, account settings or your Amazon credentials.

ReadsWhat Claude sees
Returns & claimsReturned units, their status, and reimbursement claims with case IDs
Recovery worklistWhat to file now, pending, in progress, recovered and expired, with amounts and days left to Amazon's deadline
Reimbursements & clawbacksAny Amazon reimbursement by ID or SKU, with its claim window, and reversals linked to the payment they took back
Recovery casesReimbursement discrepancies Sellerfy found, and their filing status
Inventory & costsFBA inventory per SKU and the unit costs you've entered
Inventory ledgerAmazon's ledger for a SKU: receipts, shipments, misplaced and found units, returns and removals
Profit & transactionsProfit and loss, fees and Amazon financial transactions for a date range
RMA pipelineUnits in testing and resale, and how long each has been there
FBA reconciliation & account healthShipped vs received discrepancies and your Amazon connection status
ChangesAlways asks you first
Record a claimRecords in Sellerfy a claim you've already opened in Seller Central for a returned unit (needs the Amazon case ID), so it's tracked to paid. It doesn't file anything with Amazon.
Update a claimMarks a claim in progress, submitted, approved or denied
Set a unit costUpdates the cost of a SKU, which feeds your profit numbers
Withdraw a claimPermanently deletes a claim and its evidence photos. Only when you ask for it by name.

Every change is marked as one that needs your approval, and Sellerfy tells Claude to act only on what you ask, never on instructions that appear inside your data, such as a product title or a note. Review what Claude proposes before you approve it.

Security & privacy

Your password stays with Sellerfy

You sign in on Sellerfy's own page. Claude receives a limited-access key, never your password.

Only your account

The connection is locked to the Sellerfy account you signed in with. It can't see other sellers' data or your Amazon login.

Stays connected up to 30 days

After 30 days, or if you disconnect, Claude has to be approved again. Keys are stored encrypted or hashed and checked on every request.

Every change is recorded

Each claim or cost change Claude makes is logged with who made it and when, and unusual activity alerts our team.

What you ask your AI assistant, and what it reads from Sellerfy to answer, is handled by its provider (Anthropic for Claude, OpenAI for Codex) under your account's terms with them. See our Privacy Policy for how Sellerfy handles your data.

Disconnect

claude.ai & desktop

Settings → Connectors, choose Sellerfy, then Disconnect or Remove.

Claude Code

Type /mcp, select sellerfy and choose Clear authentication. To remove it entirely run:

claude mcp remove sellerfy

OpenAI Codex

Sign out with codex mcp logout sellerfy. To remove it entirely run:

codex mcp remove sellerfy

Deleting your Sellerfy account also ends every Claude connection.

Troubleshooting

It says my account isn't enabled for the Sellerfy MCP beta.

During the beta, Claude access is turned on per account. Email us from your account's email address and we'll enable it.

The Sellerfy page says the connection link expired.

Sign-in links last 10 minutes and only work in the browser Claude opened. Start again from Claude (Connect, or /mcp → Authenticate) and finish in the same browser window.

I signed in with the wrong Sellerfy account.

Disconnect (see above), then connect again. On the Sellerfy page, sign out first if it signs you in automatically.

Claude says Sellerfy is unavailable or asks me to reconnect.

Connections end after 30 days or when you disconnect. Reconnect and approve again. If it keeps happening, email support@sellerfy.io with the time it happened.

Claude's numbers don't match my dashboard.

Claude reads the same data as your dashboard. Check the date range Claude used (it defaults to the last 90 days) and whether Amazon data finished syncing. If it still differs, send us the question and the answer.
