T6 Mem0 v2 - Implementation Summary
Date: 2025-10-13 Status: ✅ Complete - Phase 1 Implementation Repository: https://git.colsys.tech/klas/t6_mem0_v2
What Was Built
A production-ready memory system for LLM applications based on mem0.ai with:
1. REST API (FastAPI) ✅
- Location:
/api/ - Port: 8080
- Features:
- Full CRUD operations for memories
- Bearer token authentication
- OpenAPI documentation (auto-generated)
- Health checks and statistics
- Structured logging
Endpoints:
POST /v1/memories/ - Add new memory
GET /v1/memories/search - Semantic search
GET /v1/memories/{id} - Get specific memory
GET /v1/memories/user/{id} - Get user memories
PATCH /v1/memories/{id} - Update memory
DELETE /v1/memories/{id} - Delete memory
DELETE /v1/memories/user/{id} - Delete user memories
GET /v1/health - Health check
GET /v1/stats - Statistics
2. MCP Server ✅
- Location:
/mcp-server/ - Port: 8765 (stdio transport)
- Features:
- Model Context Protocol implementation
- 7 memory management tools
- Integration-ready for Claude Code
Tools:
add_memory - Add memory from messages
search_memories - Semantic similarity search
get_memory - Retrieve by ID
get_all_memories - List all for user/agent
update_memory - Update content
delete_memory - Delete by ID
delete_all_memories - Bulk delete
3. Database Setup ✅
- Supabase Migration: Vector store with pgvector
- Neo4j Configuration: Graph database for relationships
- Location:
/migrations/supabase/
Features:
- HNSW vector indexing
- Full-text search
- Metadata JSONB storage
- Similarity search functions
- Statistics functions
4. Docker Infrastructure ✅
- Location:
/docker-compose.yml,/docker/ - Network: localai (172.21.0.0/16)
Services:
neo4j - Graph database (ports 7474, 7687)
api - REST API (port 8080)
mcp-server - MCP server (port 8765)
5. Documentation ✅
- Location:
/docs/ - Framework: Mintlify
Pages Created:
- Introduction - Overview and features
- Quickstart - 5-minute setup guide
- Architecture - Technical deep dive
- Mint.json - Site configuration

Technology Stack
| Layer | Technology | Purpose |
|---|---|---|
| Core | mem0ai | Memory management |
| Vector DB | Supabase (pgvector) | Semantic search |
| Graph DB | Neo4j 5.26 | Relationships |
| LLM | OpenAI API | Embeddings + reasoning |

Configuration
Environment Variables Required
# OpenAI
OPENAI_API_KEY=sk-...
# Supabase (existing instance)
SUPABASE_CONNECTION_STRING=postgresql://...@172.21.0.12:5432/postgres
# Neo4j
NEO4J_PASSWORD=...
# API
API_KEY=...
See .env.example for complete template.
Deployment Steps
1. Clone & Configure
cd /home/klas/mem0
cp .env.example .env
# Edit .env with your credentials
2. Apply Supabase Migration
psql "$SUPABASE_CONNECTION_STRING" -f migrations/supabase/001_init_vector_store.sql
3. Start Services
docker compose up -d
4. Verify
curl http://localhost:8080/v1/health
Next Steps - Phase 2
Ollama Integration (Future)
- Add local LLM support
- Configuration-driven provider switching
- No code changes needed
Testing
- Unit tests for API endpoints
- Integration tests for MCP tools
- End-to-end workflow tests
Additional Documentation
- API endpoint examples
- MCP integration guides
- N8N workflow examples
- Python client examples
Production Hardening
- Rate limiting
- Request validation
- Error handling improvements
- Monitoring dashboards
- Backup strategies
Key Design Decisions
- Custom MCP Server: Built custom instead of using OpenMemory MCP to support Supabase + Neo4j
- Hybrid Storage: Vector + Graph + Key-Value for optimal query patterns
- Docker Network: All services on localai network for container-to-container communication
- Configuration Module: Shared config between API and MCP server
- Phase Approach: OpenAI first, Ollama later via config
Performance Targets (Based on mem0.ai)
- 26% accuracy improvement over baseline OpenAI
- 91% lower latency vs full-context approaches
- 90% token cost savings through selective retrieval

Testing the System
REST API Test
curl -X POST http://localhost:8080/v1/memories/ \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"messages": [{"role": "user", "content": "I love pizza"}],
"user_id": "alice"
}'
MCP Server Test
Add to Claude Code config:
{
"mcpServers": {
"t6-mem0": {
"command": "python",
"args": ["-m", "mcp_server.main"],
"cwd": "/home/klas/mem0"
}
}
}
Conclusion
Phase 1 implementation is complete and ready for deployment. All core functionality is implemented:

- ✅ MCP server with 7 memory tools
- ✅ Supabase vector store setup
- ✅ Neo4j graph integration
- ✅ Docker orchestration
- ✅ Comprehensive documentation
Next: Deploy, test, and iterate based on real-world usage.
