Cuthol is an open-source local NLE that AI agents can drive through MCP or CLI. Your agent cuts, captions, mixes and renders video on your machine, and checks the edit by reading text (transcripts, timings, geometry) instead of guessing from pixels.
Why it exists Most people using agents for video end up regenerating the whole composition every time they want a small change. That burns tokens and limits fast. Cuthol keeps a persistent timeline. You edit the timeline, you don t regenerate the video.
Tell your AI agent what you want and it edits the video: cuts pauses and retakes, captions every word, ducks music under the voice, adds code-based motion graphics, checks its own work and renders. Local, MIT-licensed, driven through a CLI and an MCP server.
