- Optional timestamps in plain-text transcripts
- Summarize videos — returns transcript with the prompt clearly broken out for human review before the LLM acts on it
- List playlist videos — fast enumeration of any public playlist with optional sorting
- Search videos — clean ranked results with sort and filter options, without the ads, Shorts shelves, and personalized recommendations of the YouTube website
- List available languages for any video's transcripts

youtube.com/watch?v=,youtu.be/,youtube.com/embed/,youtube.com/shorts/) or bare video IDs - Multi-language support — request transcripts in specific languages with fallback priority
Tools
get_transcript
Fetch a YouTube video's transcript. By default the response is prefixed with a [METADATA] block (title, channel, published, duration, views, description); pass include_metadata=false for transcript-only output.
| Parameter | Type | Default | Description |
|---|---|---|---|
url |
string | required | YouTube video URL or video ID |
languages |
string[] | ["en"] |
Preferred languages in priority order |
format |
string | "text" |
Output format: text, json, pretty, webvtt, srt |
preserve_formatting |
boolean | false |
Keep HTML formatting tags in the transcript |
include_timestamps |
boolean | false |
When true with format="text", prefix each line with [HH:MM:SS]. Ignored for other formats (they already include timestamps). |
include_metadata |
boolean | true |
Prepend a [METADATA] block before the transcript. Pass false for transcript-only output. |
summarize_transcript
Fetch a transcript and return it with summarization instructions. The response is structured into clearly-labeled sections ([INSTRUCTIONS], [PROMPT_SOURCE], [VIDEO], [METADATA], [TRANSCRIPT]) so a human can review the prompt before letting the LLM act on it.
| Parameter | Type | Default | Description |
|---|---|---|---|
url |
string | required | YouTube video URL or video ID |
prompt |
string | (default prompt) | Custom summarization instructions |
languages |
string[] | ["en"] |
Preferred languages in priority order |
include_timestamps |
boolean | false |
Prefix each transcript line with [HH:MM:SS]. |
include_metadata |
boolean | true |
Include a [VIDEO] block with title, channel, published, duration, views, and description. |
get_video_metadata
Fetch metadata (title, description, channel, upload date, duration, views, tags, chapters, etc.) for a YouTube video. Backed by yt-dlp.
| Parameter | Type | Default | Description |
|---|---|---|---|
url |
string | required | YouTube video URL or video ID |
list_playlist_videos
List the videos in a YouTube playlist (title, ID, channel, duration, views, URL). Per-video metadata is intentionally lean so the call stays fast even for large playlists; call get_video_metadata with a specific video ID for full detail.
| Parameter | Type | Default | Description |
|---|---|---|---|
url |
string | required | YouTube playlist URL (with ?list=...) or bare playlist ID |
limit |
integer | 500 |
Maximum videos to return |

One of: index (playlist order), title, duration, views. upload_date is not supported. |
order |
string | "asc" |
asc or desc |
search_videos
Search YouTube for videos and return a clean ranked list (title, ID, channel, duration, views, URL) — only actual videos, with no ads, recommendation shelves, or personalization. Relevance ordering still comes from YouTube's backend. Pair with get_transcript or summarize_transcript on a result's ID or URL.
| Parameter | Type | Default | Description |
|---|---|---|---|
query |
string | required | Search terms |
limit |
integer | 10 |
Maximum results to return |
sort_by |
string | "relevance" |
One of: relevance, date (newest first), views, rating |
uploaded |

Filter by length: any, short (<4 min), medium (4–20 min), long (>20 min) |
list_transcripts
