How to Use the Fomo MCP in LangChain

Q: Can I use Fomo with LangChain to track sales?

Yes. Your agent calls createevent whenever your database reports a new sale. It creates a live connection between your store's activity and your public feed.

Q: Does Fomo work well with LangChain for template testing?

It does. You can use listtemplates to pull available designs and gettemplate to verify specific copy before your agent deploys them to production.

Q: How do I monitor Fomo events in LangChain?

Use listevents to pull recent activity into your agent's memory. This lets your system analyze past performance and adjust future triggers.

Chain together real-time social proof events directly inside your LangChain agents for automated conversion tracking.

Automate event streams in LangChain

Your agent can trigger `create_event` calls the moment a purchase happens. This keeps your social proof feed accurate without manual intervention. By chaining `list_templates` into the flow, your agent selects the best message for each specific user action. It ensures your store data stays in sync with your active notifications.

Dynamic event management via MCP Server

The agent inspects current activity using `list_events` to decide if a new entry is needed. It prevents notification fatigue by checking existing logs before pushing updates. Use `update_event` or `delete_event` to correct data on the fly. Your LangChain pipeline handles these adjustments based on the logic you define in your chain.

Account oversight for LangChain pipelines

Get immediate visibility into your store status with `get_application_info`. Your agent uses this data to adjust its behavior based on account limits or configuration settings. It verifies integration health using `list_integrations`. This setup keeps your automated systems running without needing human oversight.

Setup guide

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