Installation

Local Installation (Recommended)

1. Clone this repository:

git clone https://github.com/aranej/youtube-mcp-enhanced.git
cd youtube-mcp-enhanced
npm install
npm run build

2. Add to your Claude Desktop or Claude Code configuration:

Claude Desktop (%APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "youtube": {
      "command": "node",
      "args": ["/path/to/youtube-mcp-enhanced/dist/cli.js"],
      "env": {
        "YOUTUBE_API_KEY": "your_youtube_api_key_here"
      }
    }
  }
}

Claude Code CLI (~/.claude.json):

{
  "mcpServers": {
    "youtube": {
      "command": "node",
      "args": ["/path/to/youtube-mcp-enhanced/dist/cli.js"],
      "env": {
        "YOUTUBE_API_KEY": "your_youtube_api_key_here"
      }
    }
  }
}

Configuration

Set the following environment variables:

• YOUTUBE_API_KEY: Your YouTube Data API key (required)
• YOUTUBE_TRANSCRIPT_LANG: Default language for transcripts (optional, defaults to 'en')

YouTube API Setup

1. Go to Google Cloud Console
2. Create a new project or select an existing one
3. Enable the YouTube Data API v3
4. Create API credentials (API key)
5. Copy the API key for configuration

Examples

Managing Videos

// Get video details (now includes URL)
const video = await youtube.videos.getVideo({
  videoId: "dQw4w9WgXcQ"
});

// Enhanced response now includes:
// - video.url: "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
// - video.videoId: "dQw4w9WgXcQ"
// - All original YouTube API data

// Get video transcript
const transcript = await youtube.transcripts.getTranscript({
  videoId: "video-id",
  language: "en"
});

// Search videos (results now include URLs)
const searchResults = await youtube.videos.searchVideos({
  query: "search term",
  maxResults: 10
});

// Each search result includes:
// - result.url: "https://www.youtube.com/watch?v={videoId}"
// - result.videoId: "{videoId}"
// - All original YouTube search data

Managing Channels

// Get channel details
const channel = await youtube.channels.getChannel({
  channelId: "channel-id"
});

// List channel videos
const videos = await youtube.channels.listVideos({
  channelId: "channel-id",
  maxResults: 50
});

Managing Playlists

// Get playlist items
const playlistItems = await youtube.playlists.getPlaylistItems({
  playlistId: "playlist-id",
  maxResults: 50
});

// Get playlist details
const playlist = await youtube.playlists.getPlaylist({
  playlistId: "playlist-id"
});

Enhanced Response Structure

Video Objects with URLs

All video-related responses now include enhanced fields for easier integration:

interface EnhancedVideoResponse {
  // Original YouTube API fields
  kind?: string;
  etag?: string;
  id?: string | YouTubeSearchResultId;
  snippet?: YouTubeSnippet;
  contentDetails?: any;
  statistics?: any;

  // NEW: Enhanced fields
  url: string;           // Direct YouTube video URL
  videoId: string;       // Extracted video ID
}

Example Enhanced Response

{
  "kind": "youtube#video",
  "id": "dQw4w9WgXcQ",
  "snippet": {
    "title": "Never Gonna Give You Up",
    "channelTitle": "Rick Astley",
    "description": "Official video for \"Never Gonna Give You Up\""
  },
  "statistics": {
    "viewCount": "1.5B",
    "likeCount": "15M"
  },
  // Enhanced fields:
  "url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
  "videoId": "dQw4w9WgXcQ"
}

Benefits

• Easy URL Access: No need to manually construct URLs
• Consistent Structure: Both search and individual video responses include URLs
• Backward Compatible: All existing YouTube API data is preserved
• Type Safe: Full TypeScript support available

Development

# Install dependencies
npm install

# Build TypeScript to JavaScript
npm run build

# Development mode with auto-rebuild and hot reload
npm run dev

# Start the server (requires YOUTUBE_API_KEY)
npm start

# Publish to npm (runs build first)
npm run prepublishOnly

Architecture

This project uses a dual-architecture service-based design with the following features:

• Shared Utilities: Single source of truth for all MCP server configuration (src/server-utils.ts)
• Modern McpServer: Updated from deprecated Server class to the new McpServer
• Dynamic Version Management: Version automatically read from package.json
• Type-Safe Tool Registration: Uses zod schemas for input validation
• ES Modules: Full ES module support with proper .js extensions
• Enhanced Video Responses: All video operations include url and videoId fields
• Lazy Initialization: YouTube API client initialized only when needed
• Code Deduplication: Eliminated 90% code duplication through shared utilities (407 → 285 lines)
