Frequently asked questions
Can my AI send SMS and track delivery status?
Yes. Use send_sms to deliver a text message, then get_sms_status with the returned message ID to check delivery confirmation in real time.
How does phone verification work through the AI?
Two steps: first, send_verification sends an OTP code to the user's phone. Then, check_verification validates the code the user submits. Both operations run through the 8x8 Verify API.
Can I send messages through WhatsApp and other chat channels?
Yes. The send_chat_message tool supports WhatsApp, Viber, and LINE. Just specify the channel, recipient identifier, and message text.
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.
