# Oh My Cassette

- > Oh My Cassette is an open-source AI video editing plugin and local MCP server for Claude Code, Codex, Hermes Agent, and OpenCode. It turns natural-language chat into finished montage videos on Cassette (https://trycassette.online) — beat-synced cuts, auto-matched music, subtitles, transitions, and picture-in-picture.

+ > Oh My Cassette is an open-source MCP server (PyPI: `oh-my-cassette`) that lets Claude Code, Codex, OpenCode and Hermes drive the Cassette video editor: import local media, send the user's editing requests to the Cassette agent one turn at a time, read the versioned timeline back, undo/redo, and export.

- Claude Code, Codex, Hermes Agent, and OpenCode launch the same local stdio MCP runtime. It handles media ingestion, edit planning, and job supervision; editing and rendering happen on the Cassette cloud service. Each editing turn returns a timeline delta, a CTL digest, and a contact-sheet JPEG saved locally with a clickable link, so an edit can be reviewed before anything renders. The runtime emits no editor deep link, and agents must not construct one. MIT licensed. Requires a Cassette account.

+ Hosts start it with `uvx oh-my-cassette==0.5.0`. It is a generic bridge to the Cassette MCP service (`CASSETTE_MCP_URL`, Streamable HTTP, bearer token): the editing tools, their descriptions and the workflow instructions come from that service. The bridge adds only what needs the user's machine: it transcodes local video with ffmpeg and uploads local files before a call, downloads exported files after one, and answers a typed `preparing` status while local work continues in the background. MIT licensed.
