Fetch transcripts from YouTube videos for summarization, analysis, or reference. Accepts video ID or full URL. No API key required. Triggers: YouTube transcript, video transcript, get subtitles, what did they say in the video, summarize YouTube, extract video text, caption from video.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# YouTube Transcript
Fetch transcripts from YouTube videos. Works with both auto-generated and manually added captions.
## When to Use
- Summarizing YouTube videos
- Analyzing video content without watching
- Extracting quotes or references from videos
- Any task involving YouTube video content
## Usage
```bash
youtube-transcript <video-id-or-url>
```
Accepts video ID or any YouTube URL format:
```bash
youtube-transcript EBw7gsDPAYQ
youtube-transcript https://www.youtube.com/watch?v=EBw7gsDPAYQ
youtube-transcript https://youtu.be/EBw7gsDPAYQ
```
## Output
Timestamped transcript entries:
```
[0:00] All right. So, I got this UniFi Theta
[0:15] I took the camera out, painted it
[1:23] And here's the final result
```
## Notes
- Requires the video to have captions/transcripts available (auto-generated or manual)
- No API key required
The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
