How to Use the MagicBell MCP in LangChain

Q: Can LangChain use MagicBell to trigger alerts?

Yes. Your agent uses the createbroadcast tool to send messages as part of a multi-step chain. This allows for automated alerting based on your custom agent logic.

Trigger broadcasts directly from your agent

You can push notifications straight from your reasoning chain. The `create_broadcast` tool allows your agent to initiate alerts based on logic defined in your LangChain nodes. This removes the need for manual API handling. Your agent handles the payload structure, ensuring alerts fire exactly when your chain logic dictates.

Fetch notification details for chain context

Use `get_broadcast` to pull specific notification data into your workflow. This is useful when you need to verify if an alert reached its target before proceeding with the next step in your sequence. Your agent can inspect the response to adjust its future actions. If a broadcast fails or hangs, the chain detects it immediately.

Audit notification history with list_broadcasts

The `list_broadcasts` tool provides a snapshot of all recent activity. You can feed this list into your LangChain state to analyze trends or identify bottlenecks in your alert volume. This data visibility helps your agent make informed decisions about future notifications. It keeps your pipeline aware of the current system state.

Setup guide

Set up MagicBell 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 MagicBell 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({
    "magicbell-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 MagicBell transactions"
    })
    print(result["messages"][-1].content)
