mc — MinIO AIStor command-line client

mc is a single static binary that talks to any S3-compatible object store (MinIO AIStor, MinIO, AWS S3, and others) and to the local filesystem. It has two surfaces: data-plane commands that move and inspect objects and buckets over the S3 API (ls, cp, rm, mirror, …), and control-plane mc admin commands that manage an AIStor/MinIO server itself (users, config, healing, replication, tiering). A separate mc table surface manages AIStor Iceberg Tables.

This skill teaches the model — the parts an agent gets wrong or can't cheaply discover. It does not reproduce every flag: for the exact, current flags of any command, run mc <command> --help (and mc <command> <subcommand> --help). That help is authoritative and version-matched; this skill is not.

Every remote operation targets an alias: a named endpoint + credentials. First discover what already exists, then create one only if needed:
