Cue

Video answers with timestamp-level proof

Cue gives agents a local video timeline they can search and cite: streams, chapters, subtitles, scenes, frames, and exact timestamps.

npx -y @sylphx/cue

For Claude Code:

claude mcp add cue -- npx -y @sylphx/cue

The fastest useful workflow

{
  "sources": [{ "path": "/absolute/path/to/demo.mp4" }],
  "include_subtitles": true
}

Then ask:

“Find the moment where the presenter explains the pricing change.”

Cue returns the matching timestamp, surrounding transcript, source hash, and a route to render or crop the exact frame.

Tool surface

Tool

Purpose

read_video

Build a local timeline from streams, subtitles, scenes, and keyframes

search_video

Search subtitles/transcripts and return timestamped matches

video_evidence

Render, crop, or OCR a frame at a known timestamp

Predictable defaults

  • fast probes streams and reads embedded metadata/subtitles.

  • quality explicitly requests scene detection, keyframes, OCR, or local ASR.

  • No cloud video API or frame-by-frame vision model is required.

  • Missing ffprobe, subtitles, or ASR is reported as a gap, not guessed around.

Why agents trust it

Every claim can point back to timestamp_ms, stream index, subtitle range, frame index, or source hash. Structural keyframes are preferred over sampling every frame.
