How to Use the MessageBird MCP in LangChain

Q: How do I configure the MessageBird MCP Server inside my LangChain project?

Install the required adapter using pip install langchain-mcp-adapters langgraph. Then, initialize MultiServerMCPClient with the Vinkius HTTP endpoint and pass the tools from client.gettools() directly into your agent creator.

Q: Can LangChain agents check my MessageBird budget before dispatching texts?

Yes, your agent can call getbalance to inspect remaining credits. You can configure your LangChain runnable sequence to halt execution if the balance drops below your specified threshold.

Q: How does LangChain handle batch contact lookups using MessageBird tools?

The agent uses listcontacts to retrieve multiple records in a single execution block. From there, your LangChain chain can iterate through the list and run individual lookups or group assignments dynamically.

Q: What is the best way to monitor failed SMS deliveries?

Use listmessages to fetch recent dispatches and check their status fields. If a specific message fails, your agent can trigger listhlr to verify if the recipient's phone number is still active on the carrier network.

Run multi-step messaging chains in LangChain using MessageBird to dispatch SMS and check delivery status automatically.

Chain MessageBird tools directly inside LangChain agents

Running `send_sms` inside your LangChain agent lets you trigger SMS workflows and immediately process the results. By feeding the output of one step directly into the next, your agent can run `get_balance` to verify funds before dispatching messages. This stops failed requests before they happen. You do not need to hardcode the flow. The ReAct agent decides when to pull contact details with `get_contact` or check recent dispatches using `list_messages` based on how the conversation unfolds.

Track every MessageBird MCP tool call with LangSmith

Monitoring `list_hlr` and `list_channels` inside your LangChain pipeline is simple with LangSmith tracing. When your pipeline initiates an MCP Server call, you see the exact latency and token usage for your communication tools in real time. This deep observability means you pinpoint exactly why a message failed or where a contact lookup stalled. You get clear inputs and outputs for every single execution of `get_message` without guessing.

Combine global SMS tools with LangChain integrations

Managing `get_group` and `list_groups` alongside 500+ LangChain integrations lets you build smarter messaging pipelines. Connect your existing databases and vector stores to this MCP setup to keep your communication stack unified. The agent coordinates these systems without manual glue code. It can query your internal knowledge base and then use `list_contacts` to find the right recipient, making your automated outreach hyper-targeted.

Setup guide

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