Moodle MCP Server Aql

moodle-mcp-server — AI-Powered LMS Analytics

Ask your Moodle instance anything. Get structured answers in seconds.

moodle-mcp-server is an open-source MCP (Model Context Protocol) server that connects AI agents directly to Moodle's Web Services API. It is the first reference implementation of the Agentic Query Layer (AQL) pattern — a software design pattern for giving large language models safe, permission-aware, read-only access to structured data.

Instead of learning report builders, writing SQL, or exporting CSVs, you ask questions in plain English — the AI agent queries your LMS and returns structured data.

Features

• Core query tools — course catalog, user enrollment, assignments, category navigation, site metadata, user lookup, and cache management
• Premium reporting plugins — optional tools such as course completion reports and recent activity can be attached through the plugin runtime
• LLM-agnostic — works with Claude, GPT, Gemini, Ollama, or any MCP-compatible AI client
• Zero LMS modification — uses Moodle's existing Web Services API, no plugin installation required
• Compliance-ready data handling — secure, efficient data processing with privacy by design
• Read-only — never modifies Moodle data, safe for production
• Plugin-extensible — drop new tool modules into a directory; tools and optional agent routing hints auto-register at runtime

Quick Start

Prerequisites

• Node.js 20+
• A Moodle instance with Web Services enabled
• A Moodle API token (Site administration → Plugins → Web services → Manage tokens)

Use With An MCP Client

Most users launch the server through an MCP client such as Claude Desktop:

{

"mcpServers": { "moodle-mcp-server-aql": { "command": "npx", "args": ["-y", "moodle-mcp-server-aql"], "env": { "MOODLE_URL": "https://your-moodle-instance.example", "MOODLE_TOKEN": "your-moodle-web-services-token" } } } }

Setup From Source

# Clone the repo

git clone https://github.com/csmediapro/moodle-mcp-server cd moodle-mcp-server

Install dependencies

npm install

Configure

cp packages/server/.env.example packages/server/.env

Edit .env: add your MOODLE_URL and MOODLE_TOKEN

Run (stdio mode)

npm run server:build node packages/server/dist/index.js

User field schema

User field display settings are generated per Moodle instance and stored locally at packages/server/data/user-field-schema.json. This file is intentionally ignored by git because it can include site-specific custom profile fields.

After connecting to a Moodle site, run the refresh_user_field_schema tool once to discover available standard and custom user fields. A minimal example shape is included at packages/server/data/user-field-schema.example.json.

Separately installed plugins can use this schema to flatten custom profile fields into stable keys such as school. The premium user-directory plugin, for example, uses it to cache and summarize full-user directory fields outside the OSS core.

Config identity

The core owns two different server identity fields:

• server.id — stable machine identity, for example mcp_8f3k2q9x
• server.name — human-facing display label

If server.id is missing, the core generates one once and persists it to the resolved config file before startup continues.

Environment overrides:

• MOODLE_MCP_CONFIG or MOODLE_MCP_SERVER_CONFIG — choose the config file path
• SERVER_ID — explicit server.id override
• SERVER_NAME — explicit server.name override
• SERVER_VERSION — explicit server.version override

If server.id is missing and the resolved config path is not writable, startup fails deliberately.

Using the reference client

# From the project root

cp packages/client/.env.example packages/client/.env npm run client:dev

Open http://localhost:3000

The client will auto-detect your Moodle instance and present a chat interface where you can ask questions in plain English.

Connecting an LLM

moodle-mcp-server needs an AI model to power the natural-language interface. You bring the model — the moodle-mcp-server core and reference client support any MCP-compatible provider.

Option 1: Run Locally (Recommended for Speed & Privacy)

Running a local model keeps all data on your own hardware — nothing leaves your network. Modern quantized models run well on consumer GPUs and even CPU-only setups.

Performance: A quantized 24B model on a single RTX 3090 delivers ~1.5-second responses after the first query — faster than most cloud APIs once the system is initialized.

Via Ollama (easiest)

# Install Ollama: https://ollama.com

ollama pull gemma3:12b # Fast, reliable tool use (~200ms TTFT) ollama pull qwen3:14b # Strong reasoning, good for complex queries ollama pull deepseek-r1:14b # Excellent at multi-step chains

Then point the reference client at http://localhost:11434 (Ollama's default).

Via llama.cpp (maximum control)

# Download a GGUF model (example: Devstral 24B Q4)

Run the llama.cpp server:

llama-server -m devstral-24b-Q4_K_M.gguf --ctx-size 60000 --port 8080

Point the reference client at http://localhost:8080/v1.

Recommended local models

Option 2: Cloud Providers

Anthropic (Claude):

export ANTHROPIC_API_KEY=sk-ant-...

Select "Anthropic" in the reference client's provider dropdown. Claude Sonnet offers the most reliable tool-calling behavior.

OpenAI (GPT):

export OPENAI_API_KEY=sk-...

Select "OpenAI" in the provider dropdown. GPT-4o performs well on structured queries.

Ollama Cloud: Uses the same API as local Ollama, hosted at https://ollama.com/v1. Good middle ground — faster than local cold starts, more private than big cloud providers.

Option 3: Claude Desktop (Direct MCP)

Claude Desktop connects to the moodle-mcp-server core directly over stdio — no reference client needed.

Add to your Claude Desktop config (claude_desktop_config.json):

{

"mcpServers": { "moodle-mcp-server": { "command": "node", "args": ["/path/to/moodle-mcp-server/packages/server/dist/index.js"], "env": { "MOODLE_URL": "https://your-moodle-instance.com", "MOODLE_TOKEN": "your-api-token" } } } }

Restart Claude Desktop. The server's tools will appear in Claude's tool list — ask questions directly.

Architecture

This project is a reference implementation of the Agentic Query Layer (AQL) pattern — a layer that sits between an AI agent and your data, providing permission-aware, read-only, plain-language access without exposing the underlying data to the model.

User (plain English question)

│ ▼ AI Agent (Claude / GPT / Gemini / Ollama / local) │ ▼ MCP Protocol moodle-mcp-server ← AQL connector for Moodle ├── Tool Registry (core + plugins) ├── Agent Runtime Config (core + plugin rules) ├── Optimized Data Layer (secure, efficient data handling) └── Moodle Client (REST API calls) │ ▼ Moodle Web Services API

Transport modes

• Stdio — dist/index.js — runs as a subprocess, used by Claude Desktop and similar clients

The OSS core intentionally ships with stdio only. Any network-facing wrapper, remote supervision, or premium plugin attachment belongs in a separate commercial node agent or wrapper.
