Google Merchant Center MCP server

Google Merchant Center MCP

English | Русский

A1 Google Merchant Center MCP connects an AI app to your Google Merchant Center account. Find out why products are disapproved, inspect feeds and promotions, explore reports and market prices, then make deliberate changes to product data when you need to.

It works with the Merchant Center data behind Shopping listings: products, data sources, promotions and reports. Campaigns, budgets and bids belong to Google Ads and are outside this server.

• 22 tools. 15 operations only read Merchant Center data; 5 write product, data-source or promotion data; 2 are potentially destructive.
• Your Google access. The server uses your OAuth credentials and the Merchant API v1 — it does not create a separate Merchant Center account.
• Source-aware changes. Product and promotion inputs can be changed only through an API data source. A file feed can be re-fetched, but its contents are not edited here.
• Visible boundaries. Tools carry read-only, write or destructive metadata, so an AI client can distinguish an inspection from a live change.

Start with a read-only question:

Which products are disapproved, and what issues does Google report for each?

You: Which products are disapproved, and what issues does Google report for each?

Assistant: Lists the affected products and explains the item-level issues that Merchant Center reports.

You: Show the current price and availability of product SKU-123, then prepare an availability update to in_stock.

Assistant: Shows the current product input, the API data source it belongs to and the exact change to make. It asks for confirmation before updating the live product input.

You: Confirm the update.

Assistant: Sends the update and explains that Merchant Center processes product data asynchronously. The processed product and its quality status can take several minutes to refresh.

Quick start

You need Node.js 20+, a Google Merchant Center account and a Google Cloud project registered with Merchant Center. OAuth credentials are not required at install time — the server connects from the conversation, see Getting access.

1. Add the server to your AI app using one of the instructions below.
2. Say "connect Google Merchant Center": the assistant walks you through the OAuth client and the browser consent, no config files and no restart.
3. Ask the first read-only question above.

Codex

In the app:

1. Open Settings → MCP servers.
2. Select Add server.
3. Choose STDIO, then enter the launch command npx -y mcp-google-merchants@latest and the four environment variables below.
