How to Use the Venue MCP in LangChain

Q: How does LangChain use Venue data for event tracking?

The MCP Server provides tools like geteventanalytics. You pass the resulting data to your chain, and it allows subsequent steps in your workflow to decide how that metric should be used.

Q: Can LangChain use Venue to list past recordings?

Yep. Your agent can call listrecordings after getting basic event context via geteventdetails. This lets you build a chain that confirms the venue details and then retrieves all associated video content.

Q: What if I need LangChain to find all available venues?

You use the listevents tool. This gives you a list of existing events, and then you can sequence calls to tools like geteventdetails for each one in the batch.

Q: If I need LangChain to check account info related to Venue?

The MCP Server includes a basic tool, getme, which retrieves general account information. Your agent can call this as part of validating user permissions before executing more complex venue tools.

Run complex event planning logic using LangChain to manage venues.

Plan multi-step venue booking chains.

The `list_events` tool starts your reasoning chain by fetching a list of current and upcoming events. From there, an agent can decide it needs specific data, like checking the capacity via `get_event_details`, before proposing next steps. This makes LangChain ideal for booking agents. You build pipelines where the output of listing attendees (`list_event_registrations`) feeds directly into creating a new speaker record using `create_speaker`.

Track and compare event data flows.

When you need to see what worked last time, start by calling `get_event_analytics`. This result can then be passed to another tool, like `list_recordings`, so your agent compares past engagement metrics against available content. This whole flow is visible in LangSmith. You'll track the latency and inputs for every step—like verifying event details with `get_event_details` before sending a final confirmation.

Automate venue setup from scratch.

If you're building an agent that needs to launch a new conference, it first calls `create_event`. Once the event exists, the next logical step is registering talent by calling `create_speaker`. You don't write sequential code; your ReAct agent decides this order based on the user prompt. It handles all the necessary steps—from creation to listing initial details using `list_speakers`.

Setup guide

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