FAQ

Frequently asked questions

01

Can my AI initiate phone calls?

Yes. Use create_call with an agent ID and phone number. The AI agent handles the conversation automatically.

02

Can I read call transcripts?

Yes. get_call_transcript returns the full conversation for any completed call.

03

How do I create a new voice agent?

Use create_agent with a name and system prompt. The agent will use the prompt to guide conversations.

04

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.

05

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.

06

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.
