Frequently asked questions
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.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
