What can it do?

Once connected, your AI can:

  • Extract clean, word-for-word video transcripts - no credentials required.
  • Search YouTube for videos, channels, and playlists.
  • Retrieve video stats, metadata, comments, and captions.

Getting Started

The server supports three access tiers. Pick the one that fits your use case.

Guest Mode (No Setup)

Works out of the box. The get_video_transcript tool uses yt-dlp to extract transcripts without any API credentials.

{
  "mcpServers": {
    "youtube-mcp": {
      "command": "npx",
      "args": ["-y", "@mrsknetwork/ytmcp@latest"]
    }
  }
}

API Key (Recommended)

Unlocks all public data tools. Best for search, metadata, comments, and transcripts.

1. Get a Google API Key

  1. Open the Google Cloud Console.
  2. Enable YouTube Data API v3 for your project.
  3. Go to Credentials and create an API Key.

2. Add to your MCP client config

{
  "mcpServers": {
    "youtube-mcp": {
      "command": "npx",
      "args": ["-y", "@mrsknetwork/ytmcp@latest", "YOUR_GOOGLE_API_KEY"]
    }
  }
}

OAuth 2.0

Required for private subscriptions, memberships, and account activity.

1. Create an OAuth 2.0 Client

  1. Open the Google Cloud Console.
  2. Enable YouTube Data API v3 for your project.
  3. Go to Credentials > Create Credentials > OAuth 2.0 Client ID.
  4. Set Application type to Web application.
  5. Add this exact Redirect URI: http://localhost:31415/oauth2callback.
  6. Go to OAuth Consent Screen > Test Users and add your Gmail address.

2. Add to your MCP client config

Credentials are passed securely via environment variables in the MCP config. They are never stored in files.

{
  "mcpServers": {
    "youtube-mcp": {
      "command": "npx",
      "args": ["-y", "@mrsknetwork/ytmcp@latest"],
      "env": {
        "GOOGLE_CLIENT_ID": "your-client-id.apps.googleusercontent.com",
        "GOOGLE_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

3. First-time login

On your first tool call, the AI will share a login link. Click it, authorize the app in your browser, then tell the AI you are done. Your session is saved - you won't need to log in again unless you revoke access.
