What is the Minio MCP Service MCP server?

Minio MCP Service MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Minio MCP Python Implementation.

What you get

This project implements a Model-Context Protocol (MCP) server and client for MinIO object storage. It provides a standardized way to interact with MinIO.

What the assistant can call

Once Minio MCP Service is connected, these are the calls the assistant has available:

  • Server — The Server tool exposed by this server
  • Resources — Exposes MinIO data through Resources. The server can access and provide: - Text files (automatically detected based on file extension) - Binary
  • Tools — The Tools tool exposed by this server
  • Client — 1. Basic Client - Simple client for direct interaction with the MinIO MCP server 2. Anthropic Client - Integration with Anthropic's Claude
  • Configuration — The Configuration tool exposed by this server

Setting it up

Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Configuration and credentials

You will need 4 environment variables: MINIO_ACCESS_KEY, MINIO_SECRET_KEY, SERVER_HOST, ANTHROPIC_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Minio MCP Service's toolset — Server, Resources, Tools and 2 more — is a fair guide to whether it matches your workflow. It is maintained by ucesys; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the minio mcp service mcp server does with a few real requests.
