Frequently asked questions
Can I send an SMS to multiple phone numbers at the same time?
Yes! Use the send_bulk_sms tool. You can provide an array of recipient numbers in E.164 format and a single message body to reach multiple users at once.
How do I verify a security code sent to a user?
After sending a code with send_2fa, use the verify_2fa tool. You will need the requestId from the initial send and the code provided by the user to confirm their identity.
Can I check which countries I am sending the most messages to?
Yes, the get_sms_usage_by_country tool allows you to retrieve usage statistics grouped by country, helping you analyze your global communication reach.
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.
