How to Use the Brevo MCP in LangChain

Q: How do I handle rate limits when running Brevo tools in LangChain?

Monitor the latency of tools like sendemail using LangSmith. If you hit limits, configure your LangChain runnables with exponential backoff before calling the MCP Server again.

Q: Can a LangChain agent manage my lists using this Brevo integration?

Yes. Your agent can call listcontactlists to find the correct ID, then execute createcontact to update your audience database.

Q: How does LangChain trace payload errors from Brevo tools?

Every execution of getsmtpstatistics or other tools passes through the MCP connection, logging full input and output schemas directly to LangSmith for debugging.

Q: Do I need to manually configure senders before running campaigns?

Yes. The agent uses listsenders to verify your active configurations, preventing failures when triggering createemailcampaign.

Build LangChain agents that run your marketing by linking Brevo tools directly into your multi-step pipelines.

Perplexity

Chain contact imports with live list checks

Your LangChain agent checks existing lists using `list_contact_lists` and instantly routes new sign-ups. It fires `create_contact` to add users to the right segment based on upstream data from your database. This MCP Server setup lets you trace every contact creation step inside LangSmith. You see the exact latency of the `get_contact` call before the chain triggers the next step.

Automated campaign generation in LangChain pipelines

Build LangChain chains that pull content from your database and feed it straight into `create_email_campaign`. The agent evaluates previous performance metrics using `get_smtp_statistics` to adjust the send parameters before launching. By connecting this MCP Server, your LangChain agent runs autonomous loops that check `list_senders` to ensure compliance before firing any campaign.

Transactional triggers based on agent decisions

Let your LangChain agent decide when to fire transactional messages by evaluating user behavior data and executing `send_email`. The agent queries `get_account` to verify remaining credits before attempting any dispatch. Your LangChain runnable handles the conditional branching logic, switching between `get_contact` and `send_email` based on live context.

Setup guide

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