Frequently asked questions
How can I find datasets about a specific topic like 'coffee'?
You can use the search_packages tool with the query 'café'. It will return all datasets that match the term in their title or description.
How do I get the actual download link for a data file?
First, use get_package to find the resource IDs within a dataset. Then, call get_resource with the specific ID to retrieve the download URL and file format.
Can I see which government departments publish the data?
Yes! Use the list_organizations tool to see all publishing entities. You can then use get_organization to see all datasets managed by a specific department.
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.
