MinIO storage adapter for SwarmauriSDK

Swarmauri MinIO Storage Adapter

Peagen storage adapter that saves artifacts to a MinIO or any S3-compatible bucket using the official minio Python client.

Features

• Automatically creates the target bucket if it does not already exist.
• Optional prefix argument to scope uploads without changing your keys.
• Implements upload, download, upload_dir, download_dir, and iter_prefix helpers for working with single files or directories.
• Exposes a root_uri describing the bucket and prefix (minio[s]://endpoint/bucket/prefix/).
• MinioStorageAdapter.from_uri() reads credentials from MINIO_ACCESS_KEY and MINIO_SECRET_KEY environment variables for zero-copy configuration.

Installation

Using uv

uv add swarmauri_storage_minio
# or install into an existing environment
uv pip install swarmauri_storage_minio

Using Poetry

poetry add swarmauri_storage_minio

Using pip

pip install swarmauri_storage_minio

Usage

The adapter wraps a MinIO client instance. When you instantiate it, the bucket is created if it does not already exist. Use the secure flag for HTTPS endpoints (True by default) and supply a prefix when you want to namespace all uploads under a directory.

from swarmauri_storage_minio import MinioStorageAdapter
import io

adapter = MinioStorageAdapter(
    endpoint="localhost:9000",
    access_key="minio",
    secret_key="minio123",
    bucket="peagen",
    secure=False,
    prefix="examples/",
)
uri = adapter.upload("artifact.txt", io.BytesIO(b"data"))
print(uri)

downloaded = adapter.download("artifact.txt").read()
print(downloaded.decode("utf-8"))

Note: If you store credentials as SecretStr, call .get_secret_value() when passing them to the adapter.

Config-driven instantiation

The adapter can also be created from a URI. Credentials are loaded from environment variables.

from swarmauri_storage_minio import MinioStorageAdapter

adapter = MinioStorageAdapter.from_uri("minio://localhost:9000/peagen/examples/")
print(adapter.root_uri)
