MCP agent control
Connect Claude, Cursor, Codex, or another MCP client through Settings → Agent, then let the agent perform editing operations while changes appear on the timeline.
WeftCut
WeftCut is an open-source desktop video editor that connects to Claude, Cursor, Codex, and other MCP clients for agent-assisted timeline editing. It also works as a standalone editor with captions, effects, keyframes, media analysis, and exports for macOS, Windows, and Linux.
Open-source video editing with MCP agents
WeftCut is an open-source desktop video editor designed to work with MCP-compatible AI agents. It runs on macOS, Windows, and Linux, and can connect to clients such as Claude, Cursor, and Codex so an agent can make timeline changes while the editor displays them live.
The application is also usable without an agent. Its core workflow combines conventional timeline editing with checkpoints, a visible change feed, undo, media analysis, captions, effects, audio mixing, reusable motifs, and export controls. Editing and export remain on the user's machine, while any connected agent provides the editing intelligence.
Editing and agent features
Reversible review workflow
Review a live change feed under a checkpoint and undo edits when you want to take back control of the project.
Timeline editing toolkit
Work with trimming, splitting, transitions, keyframes, Bézier curves, motion paths, effects, chroma key, captions, markers, audio mixing, and a searchable command interface.
Captions and subtitles
Transcribe speech or import SRT, VTT, and ASS subtitle files, then restyle captions across the project.
Media analysis
Use shots, pause detection, transcription, and scene description to give the agent more context before it makes edits. Local engines or configured cloud providers can supply optional speech and vision processing.
Video export
Export full timelines or selected ranges in H.264, HEVC, 10-bit AV1, ProRes, or DNxHR.
Practical use cases
Agent-assisted rough cuts
Describe operations such as removing silence, splitting footage at shot changes, labeling scenes, or restyling captions, then inspect the resulting edits on the timeline.
Manual editing and finishing
Use conventional timeline tools, keyframes, effects, transitions, markers, and audio controls when you want to shape pacing and presentation manually.
Interview and spoken-content cleanup
Analyze pauses, shots, speech, or scenes before cutting so the editing process can account for spoken content and visual structure.
Reusable titles and motion graphics
Create reusable motifs such as lower thirds or illustrated animations, preview them on the timeline, and refine them in context for repeated use.
