FAQ

Frequently asked questions

01

How can I check if a shipment is at risk of affecting my reputation?

You can use the get_shipment_sla tool with the Shipment ID. It will return the maximum dispatch time allowed to avoid penalties on your seller metrics.

02

Can the AI help me find the right category for a new product?

Yes! Use the predict_category tool by providing the product title and your site ID (e.g., MLA, MLB). The agent will suggest the most accurate category ID for your listing.

03

How do I see pending questions from buyers?

Ask the agent to run search_questions using your Seller User ID. It will list the recent questions asked by buyers on your items so you can answer them using answer_question.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
