Samantha: MCP Memory Manager

📚 Overview

Samantha is a sophisticated MCP (Model Context Protocol) server that dynamically extracts and manages user memory from LLM conversations. This memory can be shared across different LLMs, allowing for consistent personalization even when switching between models.

Samantha analyzes conversations, extracting information about learning styles, topics of interest, knowledge levels, and personal preferences, creating a comprehensive user profile that LLMs can use to provide tailored responses.

🔄 Memory Extraction Process

The memory extraction process involves:

1. Conversation Analysis: Processing text for learning style indicators, topic mentions, and preferences

2. Pattern Matching: Identifying learning patterns using NLP techniques

3. Weighted Updates: Incorporating new insights with a 30/70 weighted model (new/existing)

4. Profile Construction: Building a comprehensive user profile

5. Persistent Storage: Saving memory in JSON format for retrieval

🎮 Dashboard Features

The interactive Streamlit dashboard provides:

• User Profile Overview: Summary of all memory components

• Learning Style Management: Visual editors for VARK profiles

• Topic Network Visualization: Interactive graph of knowledge areas

• System Prompt Library: Create and rate effective prompts

• Preference Management: Track and organize user likes

• Import/Export Tools: Data backup and transfer functionality

🔧 Production Deployment

For production deployment, consider:

Docker Swarm/Kubernetes

# Deploy to Docker Swarm
docker stack deploy -c docker-compose.yml samantha

# Or with Kubernetes
kubectl apply -f k8s-deployment.yml

Multiple Instances with Load Balancing

# Example docker-compose.override.yml
services:
  samantha:
    deploy:
      replicas: 3
  
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
    depends_on:
      - samantha

Data Volume Management

The data directory contains all user profiles and should be backed up regularly:

# Backup data
tar -czf samantha-data-backup.tar.gz data/

# Restore data
tar -xzf samantha-data-backup.tar.gz

🔍 Troubleshooting

Common Issues

Logs

# View container logs
docker-compose logs -f

# Check specific container
docker logs samantha

📊 Performance Monitoring

For production deployments, add monitoring:

# With Prometheus/Grafana
docker-compose -f docker-compose.yml -f docker-compose.monitoring.yml up -d
