## What it does

A small PyPI MCP bridge that lets Claude Code, Codex, OpenCode or Hermes talk to the hosted Cassette montage agent. You import clips and a song, give a short brief and revisions in plain words, and get an exported MP4; the editing tools come from the Cassette service so they update without a plugin release.

## Use when

- cut a teaser or travel montage to a song
- revise an edit with one-line notes
- delegate montage editing to a hosted agent

## Install

- Claude Code: `claude plugin marketplace add Cassette-Editor/oh-my-cassette && claude plugin install oh-my-cassette@cassette-editor`
- Any MCP client: `uvx oh-my-cassette==0.6.0 login`
