Automate list management in LangChain

Trigger `create_acelle_list` inside your chains to segment audiences based on real-time agent reasoning. You stop manual data entry and let the agent handle list creation when specific criteria are met. Your LangChain agents use `add_acelle_subscriber` to update records as users interact with other parts of your stack. The output from one tool feeds directly into the next, keeping your mailing lists current without human intervention.

Analyze Acelle Mail performance with MCP Server tools

Plug `list_acelle_campaigns` into your LangGraph nodes to fetch recent blast data for automated reporting. Your agent parses the response to identify which subject lines hit the highest engagement marks. Use `get_acelle_campaign` to pull granular stats for a specific send. This gives your agent the context needed to adjust future messaging strategies within the same chain.

Build observable marketing pipelines

Monitor every `list_acelle_subscribers` call through LangSmith to track latency and token efficiency across your agentic workflows. You see exactly how the model interacts with your email data in real time. This MCP Server provides the raw inputs for your decision trees. By chaining these tools, you build complex logic that decides when to trigger a new campaign based on existing subscriber behavior.

Setup guide

Set up Acelle Mail 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 Acelle Mail 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({
    "acelle-mail-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 Acelle Mail transactions"
    })
    print(result["messages"][-1].content)

Common questions about Acelle Mail MCP in LangChain

Yes. You connect the tools to your agent, which then executes the logic to fetch lists or create campaigns based on your instructions.

Vinkius manages the authentication layer. You provide one endpoint token, and the server handles the rest, keeping your credentials out of your local code.

It does. Because every call is a link in a chain, your agent can pull a list, filter the subscribers, and add them to a new campaign in a single automated flow.

Your subscriber data stays within your self-hosted Acelle Mail instance. The server acts as a bridge, reading and writing only what you authorize via the tool interface.

The server uses a zero-trust architecture. It only touches subscriber emails and campaign metrics, never storing your private data on Vinkius infrastructure.
