Overview

What is AIStor MCP server?

AIStor MCP server is a Model Context Protocol (MCP) server that provides a set of tools for Large Language Models (LLMs) to interact with AIStor or MinIO object stores. It enables read, write, delete, and admin operations through natural language commands.

How to use AIStor MCP server?

Configure the server in your MCP client (e.g., Claude for Desktop) using STDIO transport with a Docker/Podman command, or StreamableHTTP transport with an HTTP endpoint. Set environment variables for MinIO endpoint, access key, and secret key. Use command‑line flags like --allow-write, --allow-delete, and --allow-admin to enable additional operations. See the README for detailed JSON configuration examples.

Frequently asked questions

1

What are the prerequisites to use AIStor MCP server?

You need Docker or Podman, AIStor or MinIO credentials (access key, secret key), and the endpoint URL. For testing you can use the MinIO Playground server.

2

How do I enable write or delete operations?

By default the server runs in read‑only mode. Add `--allow-write` and `--allow-delete` flags to the configuration to enable those operations. Use `--allow-admin` for admin functions.

3

Can I limit the number of objects listed?

Yes, use the `--max-keys` parameter. The default is 1000 objects to avoid exceeding the model’s context window.

4

What transport protocols does the server support?

It supports STDIO transport (for Claude for Desktop) and StreamableHTTP (for clients like Cherry Studio).

5

Is it compatible with MinIO?

Yes, it works with any S3‑compatible object store, including MinIO and AIStor. You can use MinIO Playground for testing.
