Implementation Status - Advanced Memory System

Overview

✅ COMPLETE: Full implementation of the Advanced Memory System as specified in the application requirements.

Implementation Summary

The advanced-memory application has been successfully implemented according to the specifications in application.md and Combining GraphRAG and Mem0_.md. This system combines GraphRAG (graph-based retrieval augmented generation) with Mem0 (memory management) via an MCP (Model Context Protocol) server.

  • ✅ Mem0 Provider: Persistent memory management with user profiles
  • ✅ Configuration System: Pydantic-based settings with environment variables
  • ✅ Logging System: Structured JSON logging with multiple handlers

📊 Data Models

  • ✅ MCP Models: Request/response structures, tool definitions
  • ✅ Knowledge Models: Entities, relationships, communities, queries
  • ✅ Memory Models: User memory, search results, conversation turns, profiles

🔧 Tools & API

  • ✅ query_knowledge_base: Global and local GraphRAG search
  • ✅ add_interaction_memory: Store conversation turns in user memory
