youtube-mcp

MCP server for YouTube. Exposes four tools to any MCP client (Claude Desktop, etc.):

Zero system dependencies. ffmpeg is bundled via static-ffmpeg and downloaded automatically on first use. No Homebrew, no manual installs.

Setup

1. Get a YouTube Data API v3 key

1. Go to console.cloud.google.com

2. Create a project → APIs & Services → Enable APIs → search "YouTube Data API v3" → Enable

3. APIs & Services → Credentials → Create Credentials → API Key

4. Copy the key

2. Install

git clone https://github.com/sparsh-gaurav/youtube-mcp.git
cd youtube-mcp
pip install -e ".[dev]"

3. Configure

cp .env.example .env
# edit .env and paste your YOUTUBE_API_KEY
# optionally add SARVAM_API_KEY to enable provider="sarvam" in transcribe_video

4. Run tests

pytest -v

5. Wire up Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
 "mcpServers": {
 "youtube": {
 "command": "/path/to/youtube-mcp/.venv/bin/python3",
 "args": ["-m", "youtube_mcp.server"],
 "cwd": "/path/to/youtube-mcp",
 "env": {
 "YOUTUBE_API_KEY": "your_key_here"
 }
 }
 }
}

Restart Claude Desktop. You can then ask things like:

"Search the latest YouTube videos about Ram Mandir fund scam and summarise them"
"Get the transcript for video dQw4w9WgXcQ"
"Transcribe this video even though it has no captions: ..."
"Transcribe this short Hindi clip using Sarvam: ..."
"What is the view count and duration of this YouTube video?"

First-run notes

• transcribe_video first call: downloads the Whisper base model (~145 MB) to ~/.cache/whisper and the bundled ffmpeg binary (~60 MB) to the Python package directory. Both are cached — subsequent calls are fast.

• Temp files: audio downloaded during transcription is stored in a system temp directory and deleted automatically after each call, whether it succeeds or fails.

Tools

get_video(video_id: str) -> VideoMetadata

get_transcript(video_id: str, language: str | None = None) -> list[TranscriptSegment]

Returns YouTube's caption segments when available.

language: BCP-47 code (e.g. "en", "hi"). Defaults to first available language.

search_videos(query: str, max_results: int = 5, language: str | None = None, order: str = "date") -> list[VideoSearchResult]

Searches YouTube via the Data API v3. Returns newest-first by default.

max_results: 1–50, default 5.
order: date (default), relevance, viewCount, rating.
language: BCP-47 relevance hint (e.g. "en", "hi"). Optional.

transcribe_video(video_id: str, language: str | None = None, provider: Literal["whisper", "sarvam"] = "whisper") -> Transcript

Downloads audio and transcribes it. Works even when YouTube captions are unavailable.

• provider="whisper" (default): runs locally via OpenAI Whisper (base model). No API key required.

• provider="sarvam": uses Sarvam AI's Saaras speech-to-text API — strong for Indian languages. Requires SARVAM_API_KEY.

Sarvam 30-second limit. Sarvam's synchronous Saaras API only accepts audio up to 30 seconds — longer videos return a 400 error. Use the default provider="whisper" for anything longer.

Each WhisperSegment:

language: BCP-47 hint (e.g. "en", "hi"). Auto-detected if omitted.
