### Description (declared)

# Youtube MCP

> Fast, minimal, and reliable YouTube MCP for AI agents.

## Install

### Claude Code

```bash
claude mcp add youtube -- uvx youtube-watch-mcp
```

> **Before publish (local dev):** point `uvx` at the checkout instead:
> `claude mcp add youtube -- uvx --from /path/to/youtube-mcp youtube-watch-mcp`

### Claude Desktop / Codex / other MCP clients

Add to the client's MCP config:

```json
{
  "mcpServers": {
    "youtube": {
      "command": "uvx",
      "args": ["youtube-watch-mcp"]
    }
  }
}
```

### CLI only

```bash
uvx --from youtube-watch-mcp youtube-watch-mcp-cli info "https://youtu.be/VIDEO_ID"
```

That's it. `uvx` pulls `youtube-watch-mcp`, `yt-dlp`, and dependencies into an isolated environment automatically. Nothing to install globally.

> **Optional:** `ffmpeg` on PATH is required **only** for `--asr` (speech-to-text on caption-less videos). Core transcript extraction needs nothing.

## Optional API key

A YouTube Data API key is **not needed** to read videos. Add one only to enable cross-YouTube **search**:

```bash
claude mcp add youtube -e YOUTUBE_API_KEY=your_key -- uvx youtube-watch-mcp
```

Transcript extraction never uses the key (YouTube only allows caption download for video owners).

## Tools

| Tool | Returns | Purpose |
|------|---------|---------|
| `get_info(url)` | title, duration, chapters, has_captions | Cheap probe before fetching. |
| `get_transcript(url, asr=False)` | file path + word count + preview | Clean transcript to disk. Returns path, not full text. |
| `search_transcript(url, query)` | timestamped snippets | Grep a long video without loading it all. |
| `get_segment(url, start, end)` | text slice | Read one time range. |

Design principle: **pull, don't dump.** Transcripts write to a local cache file; tools return a path and a short preview. The agent reads or searches on demand — long videos never flood the context.

/get_transcript $url
