Frequently asked questions
How do I track a specific shipment using its ID?
You can use the 'get_shipment' tool and provide the Flexport Shipment ID. The agent will return the most recent status, location, and estimated arrival dates for that shipment.
Can I retrieve commercial invoices for customs purposes?
Yes! The 'list_commercial_invoices' and 'list_documents' tools allow you to access the necessary paperwork for customs clearance. You can even use 'download_document' to get a temporary link to the actual file.
Is it possible to filter invoices by shipment?
Absolutely. Use the 'list_shipment_invoices' tool and provide the Shipment ID. The agent will retrieve all freight billing documents associated with that specific cargo movement.
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.
Which LangChain agent types work with MCP?
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.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
