Does this MCP server process fulfillment and orders?

No. This server strictly focuses on the Marketplace Catalog and Pricing to maintain secure boundaries. To manage orders, please use the `walmart-orders-mcp` server.

Can I update prices or inventory for multiple SKUs at once?

Yes, the agent interacts with Walmart's Bulk operations endpoint to process batch updates efficiently without rate-limit throttling.

Does this agent configure limited-time promotions for special events?

Yes. You can dynamically set promotional pricing algorithms by specifying precise start and end dates directly impacting your item's Buy Box.
