You asked Claude Sample · numbers illustrative

“How many products are disapproved, and what should I fix first?”

1 merchant_products_status Merchant Center
2 merchant_performance Merchant Center

86 products are disapproved in the US, and 71 of them for the same reason: a missing GTIN.

Five of those were in your top 20 by clicks last period. Fix those five first.

Can Claude connect to Google Merchant Center?

Yes, through MCP. SiteWide reads the Merchant Center accounts your Google login can access. It only reads: it never edits products or your feed.

The Merchant Center tools.

You never call them by name. Ask the question and Claude picks the tool.

Questions about Merchant Center and AI.

Can it fix my feed?

No. It reads product status and performance and tells you what to fix. You make the changes in your feed or in Merchant Center.

Does it work with Shopify?

Yes, if your Shopify store syncs products to Merchant Center. SiteWide reads Merchant Center directly, so it doesn’t matter where the feed comes from.

Does it work with ChatGPT and Cursor?

Yes. Any client that supports remote MCP servers can connect: Claude (claude.ai, the desktop and mobile apps, and Claude Code), ChatGPT in developer mode, Cursor and others. Clients that support MCP’s OAuth sign in to your account; for one that doesn’t, create a token URL on your account page.

Can anyone else see my data?

No. Your account is scoped to your own sites, checked on every call. What the tools return goes straight to your assistant: it isn’t stored, sold or used to train AI models. The details are in the privacy policy.

What does it cost?

The free plan is 500 requests a month across every tool, with no card. The paid plan has no request limit and starts with 30 days free, then $9 a month at the launch price, which ends October 31, and $29 after that.
