Looks things up and changes nothing. Claude Code: allow.

### `youtube_search`

- The name "youtube_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search YouTube live via SerpAPI. Returns video_results (videos), plus channels, playlists, movies and related searches. Each video result's id is the YouTube video id — feed it as `v` to youtube_video (details, related videos, comments) and to youtube_transcript. `sp` carries SerpAPI filter and next-page tokens from a prior result for pagination / refined filtering.
```

### `youtube_transcript`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a YouTube video's transcript via SerpAPI. `v` is the video id from a youtube_search result. Pick a track with language_code (default 'en' — use the video's own language), and optionally title and type ('asr' for auto-generated captions). When the requested track doesn't exist the tool falls back once to an available track (same language first, manual before auto-generated) and says so in `note`.
```

### `youtube_video`

- The description's first verb is "fetch": a word for reading.
- Tag untrusted-input: The description's first sentence says "fetch" and "comment": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Fetch a single YouTube video by id via SerpAPI: details, related videos, comments and replies. `v` is the video id from a youtube_search video_results entry. Page related videos / comments / replies with next_page_token from a prior result.
```

## Claude Code permissions

      "mcp__youtube__youtube_video",
      "mcp__youtube__youtube_transcript"
    ],
    "ask": [],
    "deny": []
  }
}
```
