How to Use the YouTube MCP in LangChain

Q: How can YouTube statistics be used with LangChain?

You build a multi-step chain. First, you use getchannel to pull raw stats. Then, the agent processes those numbers—maybe calculating growth rates—and uses that calculated data as input for another action.

Q: What is the best way to analyze YouTube content with LangChain?

Use LangChain's ability to chain tools. You can combine searchvideos results, pull deep metrics using getvideo, and then analyze community feedback via listcomments. It’s a full audit in one run.

Q: Can I search for specific YouTube videos using LangChain?

Absolutely. Your agent calls searchvideos with your keyword, gets the list of video metadata, and then you can pass those resulting titles to another tool call if needed. It’s designed for sequential data processing.

Multi-Step YouTube Audits for LangChain

Your agent decides the workflow. You can build complex chains that first use `search_videos` to find relevant content, then take those titles and pass them to a loop that calls `get_video` for detailed stats. This lets your AI client perform multi-step reasoning: it finds videos, extracts metadata from each one, and builds an overall report without you writing boilerplate code.

Channel Performance Analysis with MCP Server

Need to track a competitor? Start by calling `get_channel` to pull all the core branding and statistics for a YouTube channel. The output then feeds directly into another step that might use `list_comments` to gauge recent community sentiment. This capability lets your agent chain together data sources—from high-level stats down to individual comment threads—all within one single, traceable execution path.

Video Metadata Extraction via LangChain

When you call `get_video`, it delivers the full metadata and statistics for a specific YouTube video. You can't just stop there; your agent uses that data—like the video description—as input for the next tool, perhaps checking if related videos exist using `search_videos`. It’s all about flow. The output of one tool call immediately becomes the context and required input for the subsequent step in your chain.

Setup guide

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