Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Oh My Cassette

> 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.

Hosts start it with `uvx oh-my-cassette==0.6.0`. 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.

How to install

The exact contents, by fingerprint
mdr add cassette-editor/oh-my-cassette/llms.txt@sha256:ae753e0c6dd48766

The line at the top of this page pins the label git:20261026.474f1bc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
