Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_transcript_languagesA | List the subtitle tracks available for a YouTube video. Call this when you do not know which languages a video has, or after get_transcript reported that the requested language is unavailable. Args: url: YouTube video URL (watch, youtu.be, shorts or embed form), or the bare 11-character video id. Returns: One line per track: " - (manual|auto-generated)". |
| get_transcriptA | Get the full transcript text of a YouTube video. Returns the whole transcript as plain text without timestamps. Long videos produce long text: a two-hour video is roughly 20-30 thousand words. If the requested language is unavailable, English is used as a fallback. If neither exists, this fails and lists the languages the video does have - pick one of them and call again. Args: url: YouTube video URL (watch, youtu.be, shorts or embed form), or the bare 11-character video id. language: Language code of the wanted transcript, e.g. "en", "ru", "de". Returns: The transcript as a single plain-text string. |

Scored across 2 tools
The two tools have distinct purposes: one lists available subtitle tracks, the other retrieves a transcript in a specified language. There is no overlap in functionality, and the descriptions clarify when to use each.
Both tool names follow a consistent verb_noun pattern: 'list_transcript_languages' and 'get_transcript'. This creates a predictable and readable convention.
Two tools is slightly below the typical 3-15 range, but it is well-scoped for a focused YouTube transcript server. The count feels appropriate rather than thin, covering the core use cases.
The tool surface covers the essential lifecycle: discovering available languages and fetching the transcript. The fallback to English and error messaging that suggests other languages complement the workflow, leaving no obvious gaps.
