unofficial-magister-mcp

An MCP (Model Context Protocol) server for accessing Dutch school schedules from Magister. Enables Claude and other MCP-compatible AI assistants to query school schedules, drop-off times, and pick-up times.

Note: This is an unofficial package and is not affiliated with Magister or Iddink Group.

Why I Built This

As a parent, I found myself constantly checking the Magister app to plan our mornings and afternoons. "What time does school start tomorrow?" "When's the last class on Friday?" These questions came up daily, and I wanted my AI assistant to just... know.

This MCP server lets you ask your AI agent natural questions like:

• "What time do I need to drop off the kids tomorrow?"
• "What's the schedule for next Monday?"
• "When does school end on Wednesday?"

No more app switching. Just ask and plan.

Features

• Schedule queries - Get daily or weekly school schedules
• Drop-off/pick-up times - Quickly find first and last class times for planning
• Parent account support - Works with both student and parent accounts
• Session persistence - Saves auth state to avoid repeated logins
• Smart caching - 5-minute cache with stale-while-revalidate pattern
• API with DOM fallback - Uses Magister API with automatic fallback to DOM scraping

Requirements

• Node.js 20 or later
• A Magister account (student or parent)
• ~150MB disk space (Playwright browsers)

Installation

npm install -g unofficial-magister-mcp

Or run directly with npx:

npx unofficial-magister-mcp

Configuration

Create a .env file or set environment variables:

MAGISTER_SCHOOL=schoolname.magister.net
MAGISTER_USER=your-username
MAGISTER_PASS=your-password

Usage with Claude Code

Add to your Claude Code MCP configuration (~/.claude/claude_code_config.json):

{
  "mcpServers": {
    "magister": {
      "command": "npx",
      "args": ["-y", "unofficial-magister-mcp"],
      "env": {
        "MAGISTER_SCHOOL": "schoolname.magister.net",
        "MAGISTER_USER": "your-username",
        "MAGISTER_PASS": "your-password"
      }
    }
  }
}

How It Works

1. Authentication: Uses Playwright to automate Magister login, capturing OAuth tokens
2. Session persistence: Saves browser state to .auth-state.json to avoid re-login
3. API access: Fetches schedules via Magister's internal API
4. Fallback: If API fails, falls back to DOM scraping
5. Caching: Caches results for 5 minutes with SWR pattern

Parent Accounts

If you log in with a parent account, the server automatically detects linked children and uses the first child's schedule. Multi-child selection is planned for a future release.

Troubleshooting

"Missing required environment variables"

Make sure all three environment variables are set:

• MAGISTER_SCHOOL - The school's Magister subdomain (e.g., schoolname.magister.net)
• MAGISTER_USER - Your username
• MAGISTER_PASS - Your password

Authentication issues

1. Check the log file at /tmp/magister-mcp.log for details
2. Delete .auth-state.json to force a fresh login
3. Verify your credentials work on the Magister website

Schedule not updating

The server caches schedules for 5 minutes. If you need fresh data, wait for the cache to expire or restart the server.
