Frequently asked questions
Can I convert currencies using rates from a specific past date?
Yes. Use the convert_currency tool and provide the date parameter in YYYY-MM-DD format to perform historical conversions.
How do I limit the results to only specific currencies?
When using get_latest_rates or get_historical_rates, use the symbols parameter to provide a comma-separated list of currency codes (e.g., 'EUR,GBP,JPY').
What is the maximum range for time-series data?
The get_timeseries tool typically supports a range of up to 365 days between the start_date and end_date parameters.
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.
