Overview

AI-generated overview

Local MCP server that fetches YouTube video transcripts and metadata into an assistant's workflow, with language selection and pagination for long videos.

What you can do
  • Retrieve a plain-text transcript for a YouTube video URL
  • Retrieve timestamped transcript segments with start times and durations
  • List available transcript languages, both manual and auto-generated
  • Fetch video metadata such as title and channel information
  • Page through long transcripts in chunks using a next cursor
When to use it
Useful when you want an assistant to read, summarize, quote or search the spoken content of YouTube videos, including long lectures, conference talks and podcasts, without copying transcripts by hand.
Requirements
Runs locally over stdio; the README recommends uv/uvx (or a Docker image or the .mcpb bundle for Claude Desktop). Network access to YouTube is required. Optional proxy credentials can be supplied through environment variables such as WEBSHARE_PROXY_USERNAME, WEBSHARE_PROXY_PASSWORD, SCRAPINGANT_API_TOKEN or HTTPS_PROXY.
Before you install
Transcript requests go to YouTube, which may rate-limit or block cloud and data-center IPs; the README suggests paid residential proxy services, and ScrapingAnt access requires a paid subscription that consumes credits. Proxy credentials are passed as environment variables or command-line flags, so keep them out of shared configs. Transcripts are third-party content and may be inaccurate, especially auto-generated ones.

Installation

In SourceWeft

  1. Open Mcp Youtube Transcript in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

YouTube Transcript MCP Server

[uv] [Python Application] [pre-commit] [GitHub License] [Dockerhub]

A Model Context Protocol (MCP) server that fetches transcripts and metadata from YouTube videos directly into your LLM workflows.

Designed specifically for AI agents, it seamlessly handles long-form videos through automatic pagination and provides robust proxy support to circumvent YouTube rate limits and IP bans.

Key Features

  • Rich Transcript Retrieval: Fetch raw text, timestamped segments, and video metadata in multiple languages.
  • Smart Chunking & Pagination: Automatically chunks long transcripts (default: 50,000 characters) to prevent context window overflow, letting models page through hours of video effortlessly.
  • Resilient Proxy Support: Built-in support for residential proxies (Webshare, ScrapingAnt) and standard HTTP/HTTPS proxies to prevent IP blocks.
  • Universal Compatibility: Works with Claude Desktop, Cursor, LM Studio, Goose, and any standard MCP client.

Quick Start & Installation

[!NOTE] You'll need uv installed on your system to use uvx command.

This server communicates via standard stdio. Most MCP clients can run it directly using uvx (part of Astral uv).

General Configuration (Standard MCP JSON)

Add this entry to your client's MCP configuration file (typically under mcpServers):

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

Claude Desktop
  • GUI (Drag & Drop): Download the .mcpb bundle from the Releases page and drop it into your Claude Desktop Settings.
  • Manual Config: Add the JSON above to claude_desktop_config.json (restart Claude Desktop after saving):
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
Cursor
  1. Go to Cursor Settings > Features > MCP Servers.
  2. Click + Add New MCP Server.
  3. Name: youtube-transcript, Type: command.
  4. Command: uvx --from git+https://github.com/jkawamoto/mcp-youtube-transcript mcp-youtube-transcript
Goose

Using Docker

A Docker image for this server is available on Docker Hub. Please refer to the Docker Hub page for detailed usage instructions and documentation.

Available Tools

The server registers the following MCP tools for LLM agents:

ToolDescription
get_transcriptRetrieves the plain-text transcript for a YouTube video URL.
get_timed_transcriptRetrieves transcript segments with start times and durations.
get_available_languagesLists all available transcript languages (manual & auto-generated).
get_video_infoFetches video metadata such as title and channel information.
Tool Parameters & Schema
  • get_transcript

    • url (string, required): Full YouTube video URL.
    • lang (string, optional): Preferred language code (defaults to "en").
    • next_cursor (integer, optional): Cursor to fetch the next chunk for long videos.
  • get_timed_transcript

    • url (string, required): Full YouTube video URL.
    • lang (string, optional): Preferred language code (defaults to "en").
    • next_cursor (integer, optional): Cursor to fetch the next chunk.
  • get_available_languages

    • url (string, required): Full YouTube video URL.
  • get_video_info

    • url (string, required): Full YouTube video URL.

Advanced Configuration

Handling Long Videos (Pagination)

Long videos (e.g., lectures, conferences, podcast episodes) can quickly exceed LLM token context limits. By default, transcripts exceeding 50,000 characters are chunked. When a response is split, a next_cursor is provided so the LLM agent can autonomously query the rest.

To customize the chunk character limit, supply --response-limit. To disable pagination and fetch the entire transcript at once, set --response-limit to a negative value (e.g., -1):

json
{  "mcpServers": {    "youtube-transcript": {      "command": "uvx",      "args": [        "--from",        "git+https://github.com/jkawamoto/mcp-youtube-transcript",        "mcp-youtube-transcript",        "--response-limit",        "15000"      ]    }  }}

Avoiding IP Bans (Proxy Setup)

YouTube aggressively blocks automated transcript requests from cloud providers and data center IPs. Using residential or rotating proxies ensures uninterrupted access.

1. Webshare Residential Proxy

Set credentials via environment variables or command-line flags:

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

(CLI equivalents: --webshare-proxy-username and --webshare-proxy-password)

2. ScrapingAnt

If using ScrapingAnt, supply your API token:

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

(CLI equivalent: --scrapingant-api-token)

Accessing YouTube requires a paid ScrapingAnt Web Scraping API subscription. YouTube access requires residential proxies, which consume more ScrapingAnt credits than standard proxy requests. See the ScrapingAnt credit cost documentation for details.

3. Standard / Generic HTTP & HTTPS Proxies

Specify custom proxy endpoints via HTTP_PROXY / HTTPS_PROXY (or --http-proxy / --https-proxy):

json
{  "mcpServers": {    "youtube-transcript": {      "command": "uvx",      "args": [        "--from",        "git+https://github.com/jkawamoto/mcp-youtube-transcript",        "mcp-youtube-transcript"      ],      "env": {        "HTTPS_PROXY": "http://username:[email protected]:8080"      }    }  }}
