Permissions and safety

• Read Only connections run reads only. Write actions need a Read + Write connection.
• delete_datasource, delete_product, delete_region, delete_return_policy and remove_user are destructive, so they stay off until an owner, admin or operator enables them in Configure actions for this account.
• update_shipping_settings replaces all existing shipping services with one flat-rate service. It is a regular write action, so turn it off where agents should not change shipping.
• add_user can grant admin access to the Merchant Center account and is a regular write action.
• Product changes update what Google shows in Shopping, so review them before running.
• Write actions need the Owner, Administrator or Operator role. Members with the User role only get the enabled read actions on accounts granted to them.

Limits

• insert_product and insert_promotion need an API-based data source. Create one with create_primary_feed or create_promotion_feed first; products can't be written to file-based feeds.
• Promotions and inventory can't be deleted over MCP.
• Return policies can be created and deleted but not edited.
• Shipping can only be replaced with a single flat-rate service.
• create_local_inventory_feed creates a scheduled-fetch file data source, as Google requires for local inventory.

Example prompts

• "Using Google Merchant Center, which products are disapproved and why?"
• "Show my top 20 products by clicks over the last 30 days."
• "Which of my products are priced above the benchmark price?"
• "Are there any account-level issues affecting Shopping ads?"

Troubleshooting

• "No Merchant Center accounts found. Please ensure your Google account has access to Google Merchant Center.": sign in with a Google login that has access to the Merchant Center account, or ask an account admin to add you.
• Product or promotion writes fail with a data source error: pass the ID of an API-based data source from list_datasources, or create one first.
• "This account is connected read-only, so this action cannot be enabled for it. An owner or admin must reconnect it with Read & Write permissions.": reconnect the account and choose Read + Write.
• "This action is disabled for this connected account. An owner or admin must enable it for the account.": an owner, admin or operator can enable it in Configure actions for this account.

FAQ

Do I need a Google Cloud project?

No. You connect with Google sign-in in the InsightfulPipe app and choose the Merchant Center accounts. InsightfulPipe calls the Merchant API for you.

Can I connect several Merchant Center accounts?

Yes. The account picker lists every Merchant Center account your Google login can access, and each account you select becomes its own connection on your plan.

Can an agent publish products to my live feed?

On a Read + Write connection, insert_product and update_product change product data in an API-based data source, which feeds what Google shows. Connect Read Only or turn those actions off if agents should only report.
