Moodle MCP

Moodle MCP

An open source, read-only MCP server for Moodle. Connect it to Claude and ask about your assignments, deadlines, grades, courses, forums and notifications in plain language.

Not affiliated with or endorsed by Moodle Pty Ltd. "Moodle" is a trademark of its owner.

What you can ask

• "Which assignments do I still have to hand in this month?"
• "What's due this week, and what have I already submitted?"
• "What are my grades in Machine Learning?"
• "Any new announcements in my courses?"
• "Show me the sections and activities of my Computer Graphics course."

Tools

All tools are read-only and return concise, readable output.

Requirements

• A Moodle site with Web Services / mobile app access enabled (Moodle 4.x; developed against 4.5).
• Your own web service token (below). Functions your institution disables simply return an error for that tool.
• Node 20+ for the server (Node 22+ to deploy with Wrangler), or Docker, or a free Cloudflare account.

Setup

1. Get your Moodle URL and token

• URL: the root of your Moodle, without a page or /webservice, e.g. https://moodle.example.edu (if Moodle lives in a subfolder, include it: https://example.edu/moodle).
• Token: in Moodle, Preferences → Security keys shows a key for Moodle mobile web service. Some sites only show a label there; Reset generates a new key (and signs out your Moodle mobile app). Alternatively, if you log in with a Moodle username and password (not SSO), request one: curl -s "$MOODLE_URL/login/token.php" -d username=... --data-urlencode password=... -d service=moodle_mobile_app (type the password interactively so it doesn't end up in your shell history).

2. Configure

Copy .env.example to .env and fill in MOODLE_URL, MOODLE_TOKEN and MCP_AUTH_SECRET (generate the latter with openssl rand -hex 24). .env is git-ignored.

3. Run it, pick one

Cloudflare Workers (free, always on, no domain needed): recommended

npm ci
npx wrangler login
npx wrangler secret put MOODLE_URL        # https://your.moodle.edu
npx wrangler secret put MOODLE_TOKEN      # your Moodle web service token
npx wrangler secret put MCP_AUTH_SECRET   # openssl rand -hex 24
npm run deploy                            # prints https://moodle-mcp.<you>.workers.dev

Check Cloudflare's current free-tier limits. Try it locally first by copying your .env values to a git-ignored .dev.vars and running npm run dev:worker.

Docker / Node (self-hosted)

docker build -t moodle-mcp . && docker run --env-file .env -p 3000:3000 moodle-mcp
# or: npm ci && npm run build && npm start

Then expose it over HTTPS (for example with a Cloudflare Tunnel or Tailscale Funnel).

Local only (Claude Desktop / Claude Code, stdio): no install needed:

MCP_TRANSPORT=stdio MOODLE_URL=https://your.moodle.edu MOODLE_TOKEN=... npx -y @fabioov/moodle-mcp

MCP_AUTH_SECRET is not needed in this mode.

4. Add it to Claude

• Claude.ai: Settings → Connectors → Add custom connector. URL https://<your-host>/mcp, choose No sign-in, then Add header Authorization = Bearer <MCP_AUTH_SECRET>.
• Claude Code: claude mcp add --transport http moodle https://<your-host>/mcp --header "Authorization: Bearer <MCP_AUTH_SECRET>"
• If a client can only be given a URL, use https://<your-host>/mcp/<MCP_AUTH_SECRET>. Treat that URL as a password; the header is preferred because URLs end up in logs.

Security and privacy

• Your token acts as you: anyone who can call your endpoint can read what your token can read. Keep MOODLE_TOKEN and MCP_AUTH_SECRET in environment variables or Cloudflare secrets, never in the repo.
• The server is read-only by design and has no write tools.
• Whatever the tools return (grades, messages, names) is sent to Claude as part of your conversation. Check your institution's rules on sharing academic data with third-party services before using this, especially if you have access to other people's data (for example as a teacher).
• See SECURITY.md to report a vulnerability.

Known limitations

• Tested mainly against Moodle 4.5 with a student account. Teacher/admin roles and other versions or plugins are untested; reports and fixtures are welcome.
• Sites can disable individual web service functions, so some tools may not work everywhere.
• Large result sets are trimmed (for example, 25 assignments by default) to save context.

Development

npm ci
npm test            # unit tests with fixtures (no Moodle needed)
npm run typecheck
npm run dev         # HTTP server on :3000 (needs .env)
npm run dev:worker  # Cloudflare Worker locally (needs .dev.vars)
