Frequently asked questions
How can I filter a datatable for a specific ticker and date range?
Use the get_datatable tool and provide a JSON string in the filters parameter, such as {"ticker": "AAPL", "date.gt": "2023-01-01"}. This allows you to narrow down results precisely.
How do I check which columns are available in a dataset before querying it?
Run the get_datatable_metadata tool with the vendor_code and table_code. It will return the table's schema, including column names, types, and which fields support filtering.
What should I do if the dataset is too large for a standard query?
For very large datasets, use the request_bulk_download tool. This initiates an asynchronous export process. Once the status reaches 'SUCCEEDED', you can use get_bulk_download_file to retrieve the data.
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.
