Frequently asked questions
Can I search for a specific drug brand like 'Advil'?
Yes! Use the search_drug_labels tool with a search parameter like openfda.brand_name:"Advil". The agent will return the official SPL data including warnings and ingredients.
How can I find out how many different manufacturers produce a specific generic drug?
You can use the count_drug_labels tool. Set the count parameter to openfda.manufacturer_name.exact and use the search parameter to filter by the generic name.
Is it possible to sort results by the most recent label updates?
Yes. When using search_drug_labels, you can provide a sort parameter such as effective_time:desc to see the most recently updated labels first.
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.
