Overview

AI-generated overview

Remote MCP server that gives an assistant timestamped YouTube transcripts for single videos, channels and playlists, with optional AI caption cleanup.

What you can do
  • Fetch a timestamped markdown transcript for one YouTube video
  • Get a cleaned-up version of messy auto-generated captions, with punctuation, paragraphs and corrected names
  • Pull transcripts for a channel's most recent videos, newest first
  • Pull transcripts for every video in a playlist, in playlist order
When to use it
Useful when an assistant needs to read, quote or summarize YouTube content: a single video, a creator's recent output, or a course or series in a playlist. The polish tool helps when raw auto-captions are too messy to quote directly.
Requirements
A remote streamable HTTP endpoint; no local package or runtime. A bearer API key is required in the Authorization header, obtained from the provider's account page; a free key comes with 25 free credits. Network access to the provider is needed.
Before you install
Every successful transcript call spends credits, including repeat fetches of the same video, and channel or playlist calls charge per video returned, so costs can add up quickly. The API key is a secret sent in the Authorization header. Requests reveal which videos, channels and playlists you look up to the third-party provider.

Installation

In SourceWeft

  1. Open YouTube Transcript Downloader in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.youtubetranscriptdownload%2Ftranscripts/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

get_transcript

Get YouTube Transcript

Get the full transcript of a single YouTube video as timestamped markdown. Read-only: fetches existing captions, modifies nothing. Requires an API key; each successful call charges 1 credit, including repeat calls for the same video, so reuse a transcript already in context instead of re-fetching. Videos without captions return an error and cost nothing. Rate limit: 5 requests per 10 seconds.

Parametersvideorequired

polish_transcript

Polish YouTube Transcript

Get a cleaned-up transcript of a YouTube video's auto-generated captions: punctuation and capitalisation restored, filler and false starts removed, paragraphs added, misheard names fixed, faithful to what was said. Use when raw captions are too messy to read or quote; for a plain transcript use get_transcript. Read-only; requires an API key. Each call charges credits by transcript length (about 3 per 1,000 words, minimum 5), including repeat calls, so keep the result in context. Human-uploaded captions (already clean) and transcripts over ~7,000 words return an error without charging. Rate limit: 5 requests per 10 seconds.

Parametersvideorequired

Get Channel Transcripts

Charges 1 credit per video that returns a transcript, including repeat calls; videos without captions are skipped free. A 10-video call typically costs up to 10 credits, so start with a small limit. Rate limit: 5 requests per 10 seconds.
