Chain Cvent event data in LangChain

Feed `list_events` output directly into your logic chains to trigger downstream workflows. Your agents grab event IDs and pass them immediately to `get_event_details` without manual intervention. This MCP server treats every response as a linkable object. You map registration counts to database updates or notification triggers inside your LangGraph state.

Automate Cvent attendee management

Use `list_event_attendees` to pull participant lists for your agent to process. Your pipeline sorts these records and matches them against your custom CRM entries. Everything happens in memory. You define the sequence of calls so your agents handle registration logic based on real-time API feedback.

Schedule Cvent sessions with agents

Call `list_event_sessions` to extract agenda items for your scheduling logic. Your chain organizes these time slots into a format your calendar tools accept. This connection keeps your data flow tight. The agent resolves speaker names from `list_event_speakers` and attaches them to specific sessions automatically.

Setup guide

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