Add the MinIO MCP server to Claude Code

Config last verified Jun 1, 2026

The exact config to run MinIO in Claude Code — paste it in, restart, and the tools load.

Prerequisites

Claude Code installed.
MINIO_ENDPOINT — Hostname:port of your MinIO or AIStor server.
MINIO_ACCESS_KEY — Access key used to authenticate to the object store.
MINIO_SECRET_KEY — Secret key paired with the access key.

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.json

json

{
  "mcpServers": {
    "minio": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "MINIO_ENDPOINT",
        "-e",
        "MINIO_ACCESS_KEY",
        "-e",
        "MINIO_SECRET_KEY",
        "-e",
        "MINIO_USE_SSL",
        "-v",
        "/path/to/local/dir:/data",
        "quay.io/minio/aistor/mcp-server-aistor:latest",
        "--allowed-directories",
        "/data"
      ],
      "env": {
        "MINIO_ENDPOINT": "<MINIO_ENDPOINT>",
        "MINIO_ACCESS_KEY": "<MINIO_ACCESS_KEY>",
        "MINIO_SECRET_KEY": "<MINIO_SECRET_KEY>",
        "MINIO_USE_SSL": "<MINIO_USE_SSL>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add minio -- docker run -i --rm -e MINIO_ENDPOINT -e MINIO_ACCESS_KEY -e MINIO_SECRET_KEY -e MINIO_USE_SSL -v /path/to/local/dir:/data quay.io/minio/aistor/mcp-server-aistor:latest --allowed-directories /data

3. Restart Claude Code and confirm the MinIO tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
