Chain subscriber updates in LangChain

Feed your subscriber data directly into your chains using `upsert_subscriber`. You can push lead info from any database into your email lists without manual entry. This MCP server ensures every contact update flows through your logic. You get full visibility into the process as the agent handles the subscriber record.

Automate segment logic in LangChain

Use `create_segment` and `add_subscriber_to_segment` to build dynamic lists within your agent pipelines. Your code decides which group a user belongs to based on real-time behavior. Building these triggers inside your chain removes the need for manual sorting. The agent calls these tools to ensure your lists stay current as your data changes.

Trigger workflows via LangChain

Connect your email sequences by calling `add_subscriber_to_workflow` from your agent logic. You can start specific campaigns the moment a lead meets your criteria. This keeps your email marketing responsive to user actions. Your agent handles the timing and trigger calls while you monitor the flow in LangSmith.

Setup guide

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