FAQ
How do I connect my Walmart seller account to Claude or ChatGPT?
Connect your Walmart store to SellerFile, then add the SellerFile MCP server URL to your assistant and sign in with SellerFile when it asks. The steps for each assistant are on this page.
Can the assistant change anything in my Walmart account?
No. Every tool is read-only. The server reads the reports SellerFile already calculates and never calls Walmart on your behalf.
Which data does the assistant see?
Only the answers to the tools it calls: profit summaries and per-product rows for the period you ask about, across all your stores. Those answers are sent to the AI provider you use.
Do I need a SellerFile account?
Explaining a metric works without one. Your own numbers need a SellerFile account with a connected Walmart store; you can create one when the assistant asks you to sign in.
How do I disconnect an assistant?
Open the MCP page in the SellerFile app and choose Disconnect next to the assistant, or Disconnect all. Its next request is refused.
