Frequently asked questions
Can I send a message to a customer who hasn't messaged me in the last 24 hours?
Yes, but you must use the send_template_message tool. WhatsApp requires Meta-approved templates to initiate contact outside the 24-hour service window. For active conversations within that window, you can use the send_text_message tool for free-form replies.
How many quick-reply buttons can I send at once?
Using the send_quick_reply_buttons tool, you can send up to 3 interactive buttons along with a message block. This is ideal for helping users choose between options like 'Confirm', 'Cancel', or 'Reschedule' with a single tap.
Can I share images or PDF documents through this server?
Absolutely. Use the send_media_message tool and provide a public URL to your asset. You can specify the type as 'image' or 'document' and even add a custom caption to the message.
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.
