MCP Servers

MCP Browser YouTube Transcript

An MCP server that uses Puppeteer and headless Chrome to scrape YouTube transcripts directly from the video page UI. It provides tools for fetching plain text transcripts, timed segments with deep links, and video metadata while bypassing standard API rate limits.

README

MCP Browser YouTube Transcript

A Docker-based MCP server that uses Puppeteer (Headless Chrome) to fetch YouTube transcripts directly from the video page UI. This approach bypasses the aggressive rate limiting (HTTP 429) often encountered with standard API endpoints or youtube-dl.

Features

get_transcript: Fetch the full plain text transcript.
get_timed_transcript: Fetch the transcript with timestamps and deep links.
get_video_info: Fetch video metadata using youtube-dl-exec.

How it Works

Browser Automation: Launches a headless Chromium instance inside the Docker container.
UI Scraping: Navigates to the YouTube video URL, clicks "Show transcript", and parses the DOM elements.
Efficiency: Uses a global browser instance to avoid the overhead of launching a new browser for every request.

Usage

Docker (Recommended)

Build and run the server:

docker compose build
docker compose run --rm -i mcp-browser-youtube

Configure your MCP client (e.g., Claude Desktop, VS Code) to use the Docker command:

{
  "mcpServers": {
    "youtube-browser": {
      "command": "docker",
      "args": ["compose", "-f", "/path/to/mcp-browser-youtube-transcript/docker-compose.yml", "run", "--rm", "-i", "mcp-browser-youtube"]
    }
  }
}

Local Development

Install dependencies:
```
npm install
```
Run the server:
```
node index.js
```
