AIStor

You can deploy and use this MCP server to interact with AIStor object stores, enabling guided, AI-assisted operations such as listing buckets, describing object contents, uploading data, and managing metadata with secure admin controls.

How to use

You interact with the AIStor MCP server through an MCP-enabled client. Start by configuring a connection to either a remote MCP endpoint or a local, containerized server that exposes the MCP interface. Once connected, you can list buckets and objects, fetch metadata and tags, generate presigned URLs for objects, describe object contents with AI assistance, and perform write and delete actions if you have the proper permissions. Admin commands let you inspect server health and storage usage.

How to install

Prerequisites: you need Docker or Podman installed on your workstation, plus access credentials for an AIStor MinIO-compatible object store (MINIO_ENDPOINT, MINIO_ACCESS_KEY, MINIO_SECRET_KEY). The MCP server runs inside a container and can be configured for HTTP transport or STDIO transport depending on your client.

Additional setup and notes

Configuration for both Claude desktop clients and StreamableHTTP-enabled clients is provided below. By default, the MCP server runs in read-only mode unless you explicitly enable write, delete, and admin capabilities with the appropriate flags. Review the examples to tailor the server behavior to your security and workflow requirements.
