Video editing software designed for motion effects and versatility.

In addition to essential features like basic cut editing, animation, sound mixing, external library extensions, project management, and text editing, our software offers a wide range of powerful tools.

It also supports layer-based editing, which differs from traditional track-based editing. This approach makes it easier to apply multiple effects to individual assets, providing greater flexibility and creative control.

Editing with Claude Code

Cartcut exposes its live timeline over MCP, so Claude Code can edit the project you are looking at: cutting from a transcript, adding subtitles, trimming, restaging clips, motion, transitions and effects. Its edits land in your own undo history, so ⌘Z takes them back.

Install the plugin, which carries both the editing skill and the connection:

/plugin marketplace add cartesiancs/cartcut
/plugin install cartcut-editing@cartcut

It asks for your Cartcut MCP token once. Open Cartcut, click the ⚡ icon at the bottom right, and copy the connection command; the token is the UUID after Bearer . Then ask for an edit in plain language.

The skill is also on the skills CLI, for Claude Code and for other agents:

npx skills add cartesiancs/cartcut --skill cartcut-editing -a claude-code -g

That route installs the skill alone, so run the ⚡ panel's claude mcp add line afterwards to connect the bridge. Take one route or the other, not both.

Any other MCP client (Claude Desktop, Cursor, Codex) connects through @cartesiancs/cartcut-mcp, which is also listed in the official MCP Registry. It finds the token by itself:

npx -y @cartesiancs/cartcut-mcp

plugins/cartcut-editing/README.md has the details, including what to do when it will not connect.
