How to Use the LiveKit Real-Time Rooms MCP in LangChain

Q: Can I use LiveKit Real-Time Rooms metadata with LangChain?

Absolutely. You can call updateroommetadata to save custom JSON data, and then your agent reads that state later in the chain when it needs context.

Q: What if I want to check room status using LiveKit Real-Time Rooms with LangChain?

You can first call listrooms to see all active environments. Then, passing a specific room ID, you use listparticipants to get an immediate count and roster of who's currently connected.

Q: Does LangChain support managing access control for LiveKit Real-Time Rooms?

Yes. If the agent needs to restrict access, it uses removeparticipant. This action not only tells LiveKit to kick them out but also ensures their associated token is revoked.

Multi-Step Room Management with MCP Server

You'll start by calling `create_room`. The resulting room ID immediately feeds into a subsequent step, like using `list_participants` to check who joined. You can then chain that information—for example, updating the room settings via `update_room_metadata` with context gathered from those initial participants.

Controlled Communications Flow

Need to manage attendees? Call `get_participant` to pull detailed info on a user. If something goes wrong, the agent can revoke their access by calling `remove_participant`. You'll use these tool calls sequentially to build a complex flow that handles setup, verification, and tear-down.

Targeted Messaging and State Updates

Sending data is more than just broadcasting. Use `send_data` with either 'reliable' or 'lossy' for specific needs. After the message goes out, you can update participant status using `update_participant_metadata`, keeping track of who saw what and when.

Setup guide

Set up LiveKit Real-Time Rooms 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 LiveKit Real-Time Rooms 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({
    "tt-voice-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 LiveKit Real-Time Rooms transactions"
    })
    print(result["messages"][-1].content)
