MCP (Model Context Protocol) server for [Scriptivox](https://scriptivox.com) — AI-powered audio and video transcription.

Turn any AI assistant into a transcription powerhouse. Transcribe audio and video from URLs or local files with 99% accuracy, speaker diarization, **119 languages**, and word-level timestamps. Plus full CRUD on transcriptions (cancel, delete, list) and caption export in SRT / WebVTT / plain text.

      }
    }
  }
}
```

### Tip: always pass `language` when you know it

Auto-detection works in most cases but has a small failure rate on short clips, code-switched audio, or files starting with music. Passing the ISO code is both faster and more accurate.
