## Use when

- give your agent a real editor with layers and keyframes
- apply many effects per asset
- edit motion-heavy social videos

## Install

- Claude Code: `/plugin marketplace add cartesiancs/cartcut  then  /plugin install cartcut-editing@cartcut`
- Any MCP client: `npx -y @cartesiancs/cartcut-mcp`
