Manage Outreach Campaigns via LangChain

The `list_campaigns` tool lets your agent see every campaign currently running in SmartLead. This helps you check the overall status before starting a sequence. Want to control the flow? You can use `pause_campaign` or `resume_campaign`. Your agent handles these state changes, so you don't have to jump into the web dashboard.

Track Lead Data with LangChain

Need a list of who we're talking to? The `list_leads` tool pulls all current contacts from SmartLead. You can then feed this data directly into subsequent steps in your chain. It’s also smart enough to add new people using `add_lead`. This whole process keeps the lead flow going without manual intervention.

Analyze Performance with LangChain

Determine what's working by calling `get_campaign_analytics`. This tool gives you hard numbers on performance, letting your agent decide if a campaign needs tweaking. If the analytics point to trouble, check out `get_campaign` for deeper details. The ability to chain these calls makes decision-making automatic.

Setup guide

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