Frequently asked questions
How can I check if a carrier is currently authorized to transport goods?
You can use the get_carrier_authority tool with the carrier's DOT number. This will return the official operating authority status directly from FMCSA records.
Can I find a carrier's DOT number if I only have their business name?
Yes, use the search_carriers_by_name tool. Provide the Legal or DBA name, and the agent will return a list of matching carriers along with their U.S. DOT numbers.
Does this tool show safety ratings and inspection violations?
Yes. The get_carrier_basics tool retrieves safety performance data (BASIC measures), and get_carrier_oos provides data on Out-of-Service orders.
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.
