YouTube Transcript MCP Server: Enhanced Data Retrieval for Intelligent Applications

Overview: What is YouTube Transcript MCP Server?

The YouTube Transcript MCP Server, built on Model Context Protocol (MCP), serves as an indispensable tool for developers and AI application users looking to automate or enhance the capabilities of their applications through direct data access. By leveraging the power of MCP, this server ensures seamless integration with various intelligent tools such as Claude Desktop, Continue, Cursor, and other MCP clients, enabling them to retrieve YouTube video transcripts directly and efficiently.

🔧 Core Features & MCP Capabilities

The YouTube Transcript MCP Server focuses on retrieving transcripts from specified YouTube videos. It offers two main features:

1. Tool: get_transcript
   • Functionality: Fetches the transcript of a designated YouTube video.
   • Parameters:
     • url (string): The complete URL of the YouTube video, which is mandatory.
     • **lang (string, optional): Specifies the preferred language for the transcript. By default, it uses English (en`).

⚙️ MCP Architecture & Protocol Implementation

This server operates on a client-server model, where each AI application acts as an MCP client and communicates over HTTP/HTTPS protocols with the server using standardized commands. The communication flow is depicted in the following diagram:

Integration Process

The interaction begins when an MCP client sends a request to the YouTube Transcript Server. The server processes the request, retrieves the necessary data from external APIs or databases, and responds back with the required information.

🚀 Getting Started with Installation

To set up and use the YouTube Transcript MCP Server in various AI applications, follow these steps for different clients:

For Goose CLI

Edit your ~/.config/goose/config.yaml file as follows to enable the YouTube Transcript extension:

extensions:
  youtube-transcript:
    name: Youtube Transcript
    cmd: uvx
    args: [--from, git+https://github.com/jkawamoto/mcp-youtube-transcript, mcp-youtube-transcript]
    enabled: true
    type: stdio

This configuration ensures that the server is recognized by Goose CLI and enables its use in command-line operations.

For Goose Desktop

Add a new extension with these settings:

• Type: Standard IO
• ID: youtube-transcript
• Name: Youtube Transcript
• Description: Retrieve transcripts of YouTube videos
• Command: uvx --from git+https://github.com/jkawamoto/mcp-youtube-transcript mcp-youtube-transcript

Review the official Goose Desktop documentation for detailed instructions.

For Claude Desktop

Edit your claude_desktop_config.json file with this entry under mcpServers:

{
  "mcpServers": {
    "youtube-transcript": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/jkawamoto/mcp-youtube-transcript",
        "mcp-youtube-transcript"
      ]
    }
  }
}

After editing, restart the Claude Desktop application to apply the changes.

Installing via Smithery

To install automatically on Claude Desktop through Smithery, use this command:

npx -y @smithery/cli install @jkawamoto/mcp-youtube-transcript --client claude

💡 Key Use Cases in AI Workflows

The YouTube Transcript MCP Server can be integrated into a wide array of applications. Here are two typical scenarios where it offers significant benefits:

1. Automatic Captioning for Educational Content
   • Scenario: A learning platform wants to provide real-time captions for their video lectures.
     • Implementation: The server fetches the transcript, which can then be used to auto-generate subtitles or display live captions.
2. Content Analysis in Marketing Reports
   • Scenario: An e-commerce site needs to analyze user feedback from product review videos.
     • Implementation: By extracting transcripts and performing Natural Language Processing (NLP), companies can gain insights into customer sentiment and preferences.
