Frequently asked questions
Why do I need to use templates to send a message?
WhatsApp requires the use of pre-approved templates for any message initiated by the business or sent after 24 hours of the last customer interaction. This prevents spam and ensures high-quality communications.
Can I send PDF documents or images via the agent?
Yes! Use the send_file tool and provide the recipient's number and the public URL of the document or image. Your agent will handle the formatting and delivery automatically.
How can I check if my WhatsApp channel is currently online?
Use the get_status tool. It returns the current state of your 1msg.io instance (e.g., connected, connecting, or disconnected). This is crucial for monitoring your automation health.
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?
