YouTube MCP Integration

This project provides a Model Context Protocol (MCP) integration for YouTube, allowing LLMs to search YouTube, get video information, and retrieve transcripts via standardized tools.

Features

• YouTube Search Tool: Search for videos on YouTube with configurable result limits
• Video Info Tool: Get detailed information about a YouTube video
• Transcript Tool: Retrieve and parse the transcript of a YouTube video

Architecture

The implementation follows the Model Context Protocol (MCP) specification, which standardizes how LLMs interact with external tools and resources. The architecture consists of:

1. MCP Server: Provides YouTube functionality as MCP tools through HTTP/SSE transport
2. YouTube API Integration: Scrapes YouTube data to provide search, video info, and transcript functionality
3. MCP Client: Example client showing how to consume the MCP YouTube tools

Getting Started

Prerequisites

• Node.js 18+
• npm

Installation

# Clone the repository
git clone https://github.com/your-username/ephor-youtube-mcp.git
cd ephor-youtube-mcp

# Install dependencies
npm install

# Build the project
npm run build

Running the Server

Start the MCP server:

npm run start

The server will start on http://localhost:3000 with the following endpoints:

• SSE endpoint: /sse
• Message endpoint: /messages

Using with an MCP Client

The MCP tools can be used with any MCP-compatible client. Here’s an example of how to use the tools:

// Initialize client
const client = new Client(
  { name: 'youtube-client', version: '1.0.0' },
  { capabilities: { tools: {} } }
);

// Connect to the server
await client.connect(transport);

// Search YouTube
const searchResults = await client.callTool({
  name: 'youtube_search',
  arguments: {
    query: 'javascript tutorial',
    limit: 3
  }
});

// Get video info
const videoInfo = await client.callTool({
  name: 'youtube_get_video_info',
  arguments: {
    input: 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'
  }
});

// Get video transcript
const transcript = await client.callTool({
  name: 'youtube_get_transcript',
  arguments: {
    input: 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'
  }
});
