Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent.

How to install

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
