The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
extract_transcript Extract a YouTube transcript ~204
Pulls the transcript of a YouTube video and returns it as Markdown with timestamps. Use this whenever the user provides a YouTube URL and wants to summarise, quote, search, or otherwise process the video's spoken content. Costs credits on first fetch (1 credit ≤15min, 2 credits 15–45min, 4 credits 45min–2h, 8 credits 2h+). Cached extractions are free — videos other Scribefy users have already extracted are cached for 30 days. Returns the title, channel, duration, language, and the transcript itself split into segments with clickable timestamps.
| Name | Type | Req | Description |
|---|---|---|---|
| lang | string | – | BCP-47 language code for the captions (e.g. 'en', 'es', 'fr', 'zh-Hans'). Defaults to 'en' if omitted. |
| url | string | yes | Full YouTube URL — youtube.com/watch?v=…, youtu.be/…, or shorts. Required. |
No output schema declared.
No examples provided.
get_related_videos Get YouTube's "Up next" feed for a video ~106
Return the videos YouTube recommends after a given video — the 'Up next' / 'Related' feed. Returns up to `limit` results (default 10, max 25). Free — no credits charged. Use this to expand research from a single starting video, or to find adjacent content.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max related videos to return (1–25, default 10). |
| url | string | yes | Full YouTube URL of the seed video. |
No output schema declared.
No examples provided.
get_video_metadata Get metadata for a YouTube video (no transcript) ~95
Look up title, channel, duration, view count, upload date, and available caption tracks for a video. Does NOT pull the transcript — use extract_transcript for that. Free — no credits charged. Useful to inspect a video before deciding whether to extract, or to discover which caption languages are available.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Full YouTube URL (youtube.com/watch?v=…, youtu.be/…, or shorts). |
No output schema declared.
No examples provided.
search_videos Search YouTube videos by free-text query ~118
Search YouTube for videos matching a query string. Returns up to `limit` results (default 10, max 25) with title, channel, duration, view count, and URL. Free — no credits charged. Use this when the user asks 'find me videos about X' before chaining into extract_transcript on a specific result.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max results to return (1–25, default 10). |
| query | string | yes | Free-text search query. Same syntax YouTube's own search bar accepts. |
No output schema declared.
No examples provided.
