List the CapCut projects in the local draft library, newest first, with duration, resolution and track count. Start here — every other tool takes a project name from this list.

Read one project's timeline: every track, and every segment on it with its start time, duration, speed and the material it plays. Times are in seconds.

List the source files a project references, with size, and whether each still exists on disk. Use this to find edits broken by moved or deleted media.

Build a new CapCut project from video files, laid end to end on one track, each optionally trimmed. Creates a new project only — it never modifies an existing one, and refuses if a project of that name is already there. CapCut must be closed. Open the result in CapCut to confirm it loads.

Find the tempo and beat times of any file with audio. Returns BPM, the spacing between beats, and every beat in seconds. Useful on its own for deciding how long cuts should be.

Build a new project whose cuts land on the beat. Cut lengths come from the detected tempo; the footage for each cut is sampled evenly across the source, so a short edit surveys the whole video rather than its opening. Same safety rules as capcut_create_project.
