Yap MCP lets Claude, Cursor, VS Code, Windsurf and any MCP client transcribe local audio and video files (WAV, MP3, M4A, MP4, FLAC, OGG, Opus, WebM and more, any length) entirely on your computer with NVIDIA Parakeet TDT v3, the same speech engine as the Yap dictation app. 25 European languages are detected automatically, with optional timestamps. No upload, no API key, no account. The speech model (about 670 MB) downloads once, then it works offline. Free and open source (MIT). Built by the Yap team at O-mega Enterprise Inc.
