What you can do with Google Merchant Center MCP
Your catalog is an operating system for commerce on Google. Markifact gives your AI the reporting, diagnostics, data-source, product, inventory, promotion, and policy tools to keep it accurate and commercially ready.

Report from catalog to conversion
Analyze impressions, clicks, click-through rate, conversions, revenue, and product-level trends across Merchant Center accounts with flexible fields, filters, dates, and comparisons.
Find issues before they cost demand
Inspect processed products, approval status, destination eligibility, item issues, price competitiveness, and price suggestions to isolate exactly what is limiting visibility.

Build and manage data sources
Create, inspect, update, fetch, and delete primary, supplemental, local inventory, regional inventory, and promotions data sources without leaving the conversation.
Control the full product lifecycle
Insert new products, patch price or availability, update titles and attributes, add supplemental data, refresh products, or delete retired offers through approval-gated write operations.

Keep commerce data synchronized
Update online, local, and regional inventory, reconcile price and availability, manage shipping and return policies, and apply changes across large product groups.
Operate promotions and accounts at scale
Create and update promotions, manage conversion sources and account settings, work across several merchant accounts, and review the exact mutation before it reaches Google.
Use Merchant Center in your favorite AI.

One MCP connection brings Google Merchant Center, your wider commerce stack, and your preferred AI assistant into the same workflow.

Google Merchant Center MCP prompt examples
Start with a live catalog question. These prompts show how Markifact can audit products, repair feed issues, launch commerce data, and queue controlled optimizations.
Prepare precise catalog fixes and review them before execution.
Update availability for these 42 SKUs from the inventory file and wait for my approval.
Fix missing GTIN values for the matched products using this supplier export.
Patch titles and product types for this collection without changing any other attributes.
Delete offers that have been retired from our commerce platform for more than 60 days.
What a session actually looks like
A single request can move from product diagnosis to a prepared catalog fix without hiding the decision. Here, Claude finds stale availability, prepares 18 product updates, and stops at approval.

Example session. Claude uses Merchant Center operations (gmc_get_product_status, gmc_update_products); the product changes stop before execution and wait for your approval.
Which Merchant Center MCP option is right for you?
Google announced a Merchant API MCP alpha in May 2026 with a focus on read-only data and insights. Community servers can expose broad API coverage. Markifact provides managed full read and write operations where every catalog change waits for approval.

Open-source MCPs
Self-hosted code with broad potential coverage
Choose it if
- You want to inspect or customize projects such as gmc-mcp
- You can own OAuth, hosting, permissions, safeguards, and upgrades
Markifact
Managed full read and write commerce operations
Choose it if
- You need to create data sources and update products from your AI
