YouTube Transcript MCP Server

1. Get an API key

Your API key is the code of a KlipTools credits pack. It looks like KT-XXXX-XXXX and is shown on screen and by email right after checkout. There is no account to create: the code is the key.

Pack	Price	Credits	Downloads via MCP
Lite	$7	500,000	555
Plus	$12	1,000,000	1,111
Pro	$19	2,000,000	2,222
Enterprise	$79	10,000,000	11,111

Buy a credits pack

Credits are valid for 365 days and work across every KlipTools tool — the subtitle downloader, the SRT translator and the AI tools on kliptools.io spend the same balance.

2. Connect your client

Replace KT-XXXX-XXXX with your code in the examples below.

Claude Code

claude mcp add --transport http kliptools https://kliptools.com/mcp \
  --header "Authorization: Bearer KT-XXXX-XXXX"

Cursor

In ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "kliptools": {
      "url": "https://kliptools.com/mcp",
      "headers": { "Authorization": "Bearer KT-XXXX-XXXX" }
    }
  }
}

Claude Desktop

Claude Desktop reaches remote servers with a key through the mcp-remote bridge (needs Node.js). In claude_desktop_config.json:

{
  "mcpServers": {
    "kliptools": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://kliptools.com/mcp",
               "--header", "Authorization:${KLIPTOOLS_AUTH}"],
      "env": { "KLIPTOOLS_AUTH": "Bearer KT-XXXX-XXXX" }
    }
  }
}

The header value sits in env on purpose: on Windows, Claude Desktop does not escape spaces inside args.

claude.ai and ChatGPT (no key to paste)

In claude.ai, add a custom connector with the URL https://kliptools.com/mcp and leave the OAuth fields empty. In ChatGPT, turn on developer mode and create a connector with the same URL and OAuth authentication. Either app opens a KlipTools window: enter your pack code there, click Connect, and the app never sees the code.

Any other MCP client

Point it at https://kliptools.com/mcp with the Streamable HTTP transport. Send the header Authorization: Bearer KT-XXXX-XXXX (or X-KlipTools-Key: KT-XXXX-XXXX), or let the client sign in with OAuth: discovery, dynamic registration and PKCE are supported.

3. Tools

get_youtube_subtitles

Returns the subtitle file of a YouTube video as text, preceded by one line with the title and the credits charged and left.

• url — a watch, youtu.be or Shorts link, or the 11-character video ID.
• language — ISO 639-1 code of the track: en, es, pt, fr, de… Default en. Auto-generated captions count.
• format — srt or vtt keep the timestamps; text is the plain transcript, best for summaries. Default srt.

check_credits

Returns the credits left on your key, the expiry date, the price per download and how many downloads the balance still buys. Free to call.

How charging works

• Every successful download costs 900 credits — including a video you downloaded before. The price is the same whatever the length of the video.
• A download that fails costs nothing: no subtitles in that language, a private or deleted video, a bad link. The agent is told it was not charged.
• There is no free tier on MCP. The website's free daily downloads are for people using the page; in exchange the MCP price is 10% lower than the website's 1,000 credits.
• Each key can download up to 1,000 files a day. That limit is there to contain a leaked key, not to throttle normal use.

Try it

Once connected, ask your agent in plain language:

"Get the transcript of https://www.youtube.com/watch?v=… as plain text and summarise it in five bullet points."

Questions

What is an MCP server?

MCP (Model Context Protocol) is the open standard AI assistants use to call outside tools. Connecting this server gives your assistant a tool that fetches YouTube subtitles, so it can read a video instead of guessing what is in it.

How much does one transcript cost?

900 credits per successful download, whatever the length of the video. In money that is about $0.013 on the $7 pack and about $0.007 on the $79 pack. Failed downloads cost nothing.

Which languages are available?

Any language the video has subtitles in, including YouTube's auto-generated captions. Ask for it with its two-letter code, such as en, es, pt, fr or de. If that track does not exist, the tool says so and you are not charged.

Does it work with Claude, ChatGPT and Cursor?

Yes. Claude Code, Cursor and Claude Desktop connect with the key as shown above. claude.ai and ChatGPT connect with the URL alone: they open a KlipTools sign-in window where you enter your pack code once.

Is there a free trial?

Not on MCP — every download is paid. To test before buying, use the subtitle downloader page, which gives three free downloads a day. The smallest pack, $7, covers 555 MCP downloads.

What if my key leaks?

Anyone holding the code can spend its credits, so keep it out of shared repositories. The daily limit of 1,000 downloads per key caps the damage. If that happens, write to us from the address below.
