How to Use the WhatsApp Business Alternative MCP in LangChain

Q: How does the WhatsApp Business Alternative connect with LangChain?

The MCP Server exposes specific tools—like sendtextmessage or getbusinessprofile—that your LangChain agent can call. This means you don't write complex API code; you just chain tool calls together in a multi-step process.

Q: If I use WhatsApp Business Alternative, how does it affect my data privacy with LangChain?

This server touches account and profile information (e.g., getbusinessprofile output). All tool calls are observed via LangSmith tracing, so you know exactly what data was accessed during the chain run.

Q: Can WhatsApp Business Alternative handle message management using LangChain?

Absolutely. You can use listmessagetemplates to pull a list of templates and then decide if you need to delete one with deletemessagetemplate. The agent decides the whole sequence.

Q: What is the best way to send messages using WhatsApp Business Alternative and LangChain?

You should use sendtemplatemessage for reliable communication. Since it's a structured template, your multi-agent chain can ensure all required parameters are filled before sending.

Managing WhatsApp Templates

Use `list_message_templates` to see all available message templates for your account. This lets you check which pre-approved formats are ready to go before sending anything. Then, if you need to remove an old template, just call `delete_message_template`. It handles the deletion directly on the backend.

Handling Profile Data

Need basic info about your WhatsApp Business setup? The `get_business_profile` tool pulls that data for you. You get a quick look at what's registered under your account. If you need to check the core details of the WABA account, use `get_waba_details`. This gives you deeper insight into the main credentials.

Sending Messages

To start a conversation, call `send_template_message` and send out pre-approved templates. You'll specify which template to use and what variables need filling. For immediate customer service needs, you can execute `send_text_message`. Remember, this usually requires an active customer service window being open.

Setup guide

Set up WhatsApp Business Alternative MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes WhatsApp Business Alternative tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "whatsapp-business-alternative-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent WhatsApp Business Alternative transactions"
    })
    print(result["messages"][-1].content)
