Free, open-source desktop video editor for macOS, Windows and Linux that you can also hand to an AI agent over MCP.
About WeftCut
WeftCut is a free, open-source non-linear video editor for macOS (Apple Silicon), Windows and Linux. It has an A/B-roll timeline, keyframes with a curve editor, effects and transitions, captions, a role-based audio mixer and hardware-accelerated export, and everything you do by hand can also be done by an AI agent: a local MCP server exposes all editing tools, so Claude, Codex or any MCP client can edit the project you are watching, with checkpoints you can restore in one click. AI features are optional: connect your own MCP agent; transcription uses your own API key or an optional local model. Pre-1.0 (v0.5) and under active development. The macOS build is Apple Silicon only and not notarized (allow it via Privacy & Security > Open Anyway); the Windows installer is unsigned. Windows and Linux builds download updates automatically by default (can be turned off). Licensed MIT; installers bundle FFmpeg under its own licenses.
