Gergy AI - MCP Architecture Foundation

Gergy AI is an intelligent assistant powered by Model Context Protocol (MCP) architecture, designed to provide cross-domain intelligence across five key life areas: Financial, Family, Lifestyle, Professional, and Home management.

🏗️ Architecture Overview

This foundational implementation provides the shared infrastructure that all five MCP servers will build upon:

Shared Infrastructure

• Database Layer: PostgreSQL with JSONB for flexible schema and cross-domain knowledge storage

• Caching Layer: Redis for high-performance caching with cross-domain relevance

• Pattern Recognition: Intelligent cross-domain pattern detection and suggestions

• Cost Management: Distributed API budget tracking and optimization

• Base MCP Framework: Foundation class for all domain servers

Domain Servers

1. Financial Server - Budget management, expense tracking, investment insights

2. Family Server - Event planning, relationship management, family coordination

3. Lifestyle Server - Health, fitness, personal development, leisure activities

4. Professional Server - Career development, skill tracking, professional networking

5. Home Server - Home maintenance, improvement projects, household management

🚀 Quick Start

Prerequisites

• Python 3.10+ (tested with 3.10.12)

• Docker and Docker Compose

• PostgreSQL client tools (optional for manual access)

• Redis client tools (optional for manual access)

Note: PostgreSQL and Redis will run in Docker containers, so you don't need them installed locally.

Installation

1. Clone and setup:

git clone <repository-url> gergy-mcp
cd gergy-mcp

2. Environment configuration:

cp .env.example .env
# Edit .env with your specific configuration

3. Start the infrastructure:

docker-compose up -d postgres redis

4. Install dependencies:

pip install -r requirements.txt

5. Initialize database:

python -c "
from shared.models.database import DatabaseConfig
import os
config = DatabaseConfig(os.getenv('DATABASE_URL'))
config.create_tables()
print('Database initialized successfully')
"

🛠️ Key Features

Cross-Domain Intelligence

• Pattern Recognition: Automatically detects patterns across domains (e.g., financial decisions affecting family plans)

• Knowledge Sharing: Unified knowledge base accessible across all servers

• Context Awareness: Maintains conversation context and suggests relevant cross-domain insights

Performance & Cost Optimization

• Smart Caching: Redis-based caching with cross-domain relevance scoring

• Cost Tracking: Real-time API usage monitoring with budget alerts

• Pattern-Based Suggestions: Reduces API calls through intelligent pattern matching

Scalable Architecture

• Modular Design: Each domain server inherits from BaseMCPServer

• Database Flexibility: JSONB fields allow schema evolution without migrations

• Containerized Deployment: Docker Compose for easy scaling and deployment

📊 Database Schema

Core Tables

• knowledge_items: Cross-domain knowledge with flexible JSONB metadata

• user_sessions: Conversation tracking and context accumulation

• temporal_cache: Expiration management and cross-module relevance

• cross_domain_patterns: Pattern recognition system

• api_usage_analytics: Cost tracking per server

Example Usage

from shared.services.database_service import DatabaseService
from shared.services.pattern_recognition_service import PatternRecognitionService

# Initialize services
db_service = DatabaseService("postgresql://...")
pattern_service = PatternRecognitionService(db_service)

# Store knowledge across domains
await db_service.store_knowledge(
    domain="financial",
    title="Budget Planning",
    content="Monthly budget analysis...",
    metadata={"category": "planning", "priority": "high"},
    keywords=["budget", "planning", "monthly"]
)

# Detect cross-domain patterns
patterns = await pattern_service.analyze_conversation(
    content="Planning a family vacation",
    domain="family",
    session_id="user_123"
)

🔧 Configuration

Environment Variables

Key configuration options in .env:

# Database
