Frequently asked questions
Can I send messages to members through the AI agent?
Yes. The send_message tool sends a direct message to a member. Provide a JSON payload with the member_id, content (the message text), and type (message type). Use list_members first to find the member ID.
Can I view the full conversation history with a member?
Yes. Use list_conversations to see all active conversations, then get_conversation with a specific conversation ID to retrieve the full message thread including sender, timestamp, and content for each message.
Can I create new member profiles and manage their contact information?
Yes. Use create_member with a JSON payload containing first_name, last_name, email, phone, and other contact details. Use list_members to browse existing members and get_member to inspect a specific profile.
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.
