justtranscribe-mcp

MCP server for JustTranscribe — transcribe public videos and audio into accurate, timestamped text without leaving your AI assistant. Paste a YouTube, TikTok or Instagram link in the chat; get the transcript back, export SRT/TXT/Markdown, or pull the AI breakdown of a social video. Spanish, English and dozens of languages are auto-detected.

Two ways to connect — both use the same API key and the same account limits:

	Transport	For
Hosted https://justtranscribe.ai/api/mcp	Streamable HTTP	Claude Code, Cursor, any client that supports remote servers with headers
This package npx justtranscribe-mcp	stdio	Claude Desktop and other stdio-only clients

Setup

1. Create a free API key at https://justtranscribe.ai/api-keys (free during the beta, no card).
2. Add the server to your client.

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "justtranscribe": {
      "command": "npx",
      "args": ["-y", "justtranscribe-mcp"],
      "env": { "JUSTTRANSCRIBE_API_KEY": "jt_live_..." }
    }
  }
}

Claude Code (hosted variant — no install):

claude mcp add --transport http justtranscribe https://justtranscribe.ai/api/mcp \
  --header "Authorization: Bearer jt_live_..."

Claude Code plugin

This repo is also a Claude Code plugin. It runs this package as a local MCP server and adds a transcribe skill that knows the limits and the export formats.

/plugin marketplace add anthropics/claude-plugins-community
/plugin install justtranscribe@claude-community

Set your key once (create one free at https://justtranscribe.ai/api-keys) and restart Claude Code:

export JUSTTRANSCRIBE_API_KEY=jt_live_...

Then:

/justtranscribe:transcribe https://www.youtube.com/watch?v=jNQXAC9IVRw

Prefer signing in to pasting a key? Use the hosted server directly instead of the plugin — claude mcp add --transport http justtranscribe https://justtranscribe.ai/api/mcp — which runs an OAuth sign-in. (A plugin's .mcp.json only loads local stdio servers, so the plugin ships the npx variant.)

To try the plugin before it is listed, clone this repo and run claude --plugin-dir ./justtranscribe-mcp.

Tools

• transcribe_url — start transcribing a public video/audio link (YouTube, TikTok, Instagram, Facebook, Pinterest, Google Drive). Returns an id; processing takes minutes.
• get_transcript — poll by id; returns the full text once complete (optionally timestamped segments and the AI analysis).
• list_transcripts — the account's transcripts, newest first.
• export_transcript — TXT, SRT, VTT, Markdown or CSV as text.
• delete_transcript — permanently remove a transcript and its media.
• get_account — identify the key's account and limits.

Limits

Public links only (no private or login-required videos, no live streams), up to 150 minutes per recording. The server enforces the same limits as the app and the REST API: 120 requests/minute per key, 3 new transcripts/hour, one processing at a time during the beta. File upload isn't possible over MCP — use the app or the REST API.

Environment

• JUSTTRANSCRIBE_API_KEY (required) — your jt_live_… key.
• JUSTTRANSCRIBE_API_URL (optional) — API origin override; defaults to https://justtranscribe.ai.
