mc (MinIO Client)

mc is the MinIO command-line client for S3-compatible object storage, and it works with RustFS out of the box.

Install

brew install minio/stable/mc

Or download a binary from the official install guide.

Configure

Create an alias pointing at your RustFS endpoint. Replace http://localhost:9000 with your server address, and use your own access keys:

mc alias set rustfs http://localhost:9000 <your-access-key> <your-secret-key>

Added `rustfs` successfully.

mc uses path-style requests by default, which is what RustFS expects. The default region is us-east-1.

Verify

Create a bucket:

mc mb rustfs/my-bucket

Bucket created successfully `rustfs/my-bucket`.

Upload a file:

mc cp /path/to/hello.txt rustfs/my-bucket/

/path/to/hello.txt: 12 B / 12 B  100.00% 1.2 KiB/s 0s

List the bucket:

mc ls rustfs/my-bucket

[2026-07-15 10:30:00 UTC]    12B STANDARD hello.txt
