Learning Hub MCP

Learning Hub MCP

learninghub.cc

Beta — fully functional, tested with one family. Feedback and bug reports welcome via GitHub Issues.

MCP server for student learning workflow with SQLite database. Each instance serves one student — deploy a separate instance per child for isolated, focused AI tutoring.

Features

• Subjects - school subjects with multi-country support (UA, CZ, DE, etc.)
• Grades - grade tracking with 5-point European scale (1=best, 5=worst)
• Topics - subject topics for improvement tracking
• Homework - assignment tracking with deadlines
• Bonus Tasks - motivational tasks that reward game minutes
• Game Minutes - immutable transaction ledger for tracking earned/spent game time
• Books - textbook library with markdown summaries and content indexing
• Topic Reviews - reinforcement tracking for weak topics
• Escalation - bad grade notifications for parents
• Instruction Tools - markdown algorithms that guide AI agents through workflows
• Sync Providers - pluggable sync framework (EduPage, PRONOTE)
• Secrets - secure credential storage for sync providers

Installation

# Install dependencies
poetry install

# Initialize database
poetry run alembic upgrade head

Configuration

Database defaults to ./data/learning_hub.db. Override via environment variable:

DATABASE_URL=sqlite+aiosqlite:///./data/learning_hub.db

Sync provider credentials (EduPage, PRONOTE, etc.) are stored in the secrets table and managed via MCP tools (set_secret, list_secrets).

Config System (SQLite)

Runtime configuration stored in the configs table. Managed via MCP tools (get_config, set_config, list_configs). Use check_system_readiness to verify all required configs are set.

Entries with defaults (seeded by migration)

Required entries (must be set before use)

Usage

Run MCP Server

poetry run learning-hub-mcp

OpenClaw Bridge Plugin

The learning-hub-bridge/ directory contains a TypeScript plugin that makes all MCP tools available as native OpenClaw agent tools.

Why

OpenClaw doesn't support MCP servers natively. Without the bridge, the agent would need exec + mcporter — slow (~3s per call), buggy (mcporter serialization issues with lists), and invisible to the model (tools not in tool list).

How it works

1. On gateway startup, the bridge spawns the Python MCP server as a child process (STDIO)
2. Discovers all tools via client.listTools() (MCP protocol)
3. Registers each as a native OpenClaw tool via api.registerTool() with prefix learning_hub_
4. Proxies execute() → client.callTool(), merging multiple TextContent blocks into a single JSON array
5. Auto-reconnects if the Python process dies

After this, the model sees learning_hub_list_subjects, learning_hub_add_grade, etc. directly in its tool list.

Deployment

The bridge must be installed as an OpenClaw extension. The source lives in learning-hub-bridge/ inside this repo, but OpenClaw loads plugins from ~/.openclaw/extensions/<pluginId>/.

Step 1. Copy the bridge to extensions:

cp -r /path/to/learning-hub-mcp/learning-hub-bridge ~/.openclaw/extensions/learning-hub

Step 2. Install dependencies:

cd ~/.openclaw/extensions/learning-hub
npm install

Step 3. Add plugin config to openclaw.json:

{
  "plugins": {
    "entries": {
      "learning-hub": {
        "enabled": true,
        "config": {
          "command": "/bin/bash",
          "args": ["-lc", "cd /path/to/learning-hub-mcp && exec .venv/bin/learning-hub-mcp"],
          "cwd": "/path/to/learning-hub-mcp",
          "toolPrefix": "learning_hub"
        }
      }
    }
  }
}

Step 4. Allow tools for the agent in openclaw.json:

{
  "agents": {
    "list": [
      {
        "id": "main",
        "tools": {
          "alsoAllow": ["learning-hub"]
        }
      }
    ]
  }
}

Step 5. Restart gateway:

openclaw gateway restart

Config options

Updating after MCP changes

When new tools are added to the MCP server, the bridge picks them up automatically on gateway restart — no bridge code changes needed. Just restart:

openclaw gateway restart

Development

# Run tests

# Run tests with coverage
poetry run pytest --cov=learning_hub

# Lint code

# Fix lint issues
poetry run ruff check --fix .

Known Limitations

• Tested with a single family (one student, two schools: EduPage CZ + UA)
• PRONOTE sync implemented but minimally tested
• SQLite only — designed for single-family self-hosted use
• Requires OpenClaw as the AI agent runtime
• Edge cases with diverse school configurations are likely not yet covered
