The Goodies - Smart Home Knowledge Graph System

🏠 Overview

The Goodies is a modern smart home knowledge graph data store layer built around the Model Context Protocol (MCP) architecture. The system provides a unified interface for managing smart home devices, relationships, and automations through a graph-based data model.

Current Status: ✅ Production Ready - All tests passing (225/225), comprehensive MCP functionality, full client-server synchronization, and enterprise-grade security features.

Related Projects: adrianco/consciousness is an early prototype of the backend server that will be rewritten from scratch later. adrianco/c11s-house-ios is a native Swift iOS app that is the front end for the system. This repo is the knowledge graph protocol that will interface the app to the backend, and includes a command line client in Python that acts as a prototype implementation for the next phase, adrianco/the-goodies-swift, which will be integrated with adrianco/c11s-house-ios.

🔐 Security Features (Phase 5)

The system includes enterprise-grade security features that have been fully implemented and tested:

Core Security Features

• ✅ Authentication System - Admin password login with Argon2id hashing
• ✅ JWT Tokens - Secure token-based API access with configurable expiration
• ✅ Rate Limiting - Brute force protection (5 attempts/5 min window)
• ✅ Audit Logging - Comprehensive security event tracking with 15 event types
• ✅ Guest Access - QR code-based temporary read-only access
• ✅ Progressive Delays - Increasing lockout periods (up to 5x) for repeated failures
• ✅ Permission System - Role-based access control (admin/guest)

Security Configuration

1. Development Setup (Quick Start)

# For development/testing - uses "admin" as the default password
export ADMIN_PASSWORD_HASH=""
export JWT_SECRET="development-secret"
 
# Start the server
python -m funkygibbon

2. Production Setup (Secure)

# Option A: Use the installer (recommended)
./install.sh
# The installer will:
# - Prompt for a secure admin password
# - Generate password hash automatically
# - Create a secure JWT secret
# - Set up start_funkygibbon.sh with your configuration
 
# Option B: Manual setup
# Step 1: Generate a secure password hash
python -c "from funkygibbon.auth import PasswordManager; pm = PasswordManager(); print(pm.hash_password('YourSecurePassword123!'))"
 
# Step 2: Set environment variables with generated values
export ADMIN_PASSWORD_HASH="$argon2id$v=19$m=65536,t=2,p=1$..."  # Use output from step 1
export JWT_SECRET="$(openssl rand -hex 32)"  # Generate secure random string
 
# Step 3: Start the server
python -m funkygibbon

3. Security Environment Variables

Authentication Usage

Admin Login

# Login with admin password
curl -X POST http://localhost:8000/api/v1/auth/admin/login \
  -H "Content-Type: application/json" \
  -d '{"password": "admin"}'
 
# Save the access token from response
export AUTH_TOKEN="<access-token-from-response>"
 
# Use token for authenticated requests
curl http://localhost:8000/api/v1/auth/me \
  -H "Authorization: Bearer $AUTH_TOKEN"

Guest Access (QR Code)

# Generate guest QR code (requires admin token)
curl -X POST http://localhost:8000/api/v1/auth/guest/generate-qr \
  -H "Authorization: Bearer $AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"duration_hours": 24}'
 
# Response includes QR code image and guest token

Security Implementation Details

Rate Limiting

• Protection: Prevents brute force attacks on authentication endpoints
• Configuration: 5 attempts allowed per 5-minute window per IP address
• Progressive Delays: Failed attempts result in increasing lockout periods (up to 5x)
• Response: HTTP 429 (Too Many Requests) with Retry-After header
• Automatic Cleanup: Old rate limit entries cleaned up hourly

Audit Logging

• Coverage: All authentication attempts, token operations, and permission checks
• Event Types: 15 different security events tracked including:
  • Authentication success/failure/lockout
  • Token creation/verification/expiration
  • Permission grants/denials
  • Guest access generation
  • Suspicious pattern detection
