Chain SMS and Email Operations

You can sequence your marketing logic by passing the output of `list_email_campaigns` directly into your next agent step. This lets your agent evaluate performance data before triggering follow-up actions. Your agent handles the logic flow across `send_transactional_email` and `send_sms_broadcast` without manual intervention. It's a clean way to manage multi-step messaging workflows within your chains.

Automate Listrak Contact Management

Feed contact data from internal databases into `create_sms_contact` to keep your lists synced. The agent determines when to add users based on your custom business logic. Use `get_email_contact_details` to pull specific user profiles for context-aware responses. This creates a tight loop between your user data and your messaging platform.

Monitor Listrak Tool Execution

Every interaction with the Listrak MCP Server is logged via your existing observability stack. You track latency and tool inputs for every call. Debugging becomes a matter of inspecting your chain traces. You see exactly what the agent sent to `subscribe_to_sms_list` and why it made that decision.

Setup guide

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

Common questions about Listrak MCP in LangChain

Install the necessary adapters and initialize the client with your endpoint. Pass the list of tools to your agent setup to allow for immediate interaction.

The server relies on the API's native limits. You should implement retry logic within your chain to handle any temporary throttling during bulk operations.

Your API tokens are handled by the Vinkius environment. Data is encrypted in transit, and no raw credentials touch your local application code.

You can use the tool to trigger broadcasts, but ensure your logic handles the payload structure required by the API.

The agent receives the error response directly. You can write fallback chains to handle these failures gracefully.
