||||
- Structured logging
|
||||
|
||||
**Endpoints**:
|
||||
```
|
||||
POST /v1/memories/ - Add new memory

## Configuration
|
||||
|
||||
### Environment Variables Required
|
||||
|
||||
```bash
|
||||
# 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
|
||||
```bash
|
||||
cd /home/klas/mem0
|
||||
cp .env.example .env
|
||||
# Edit .env with your credentials
|
||||
```
|
||||
|
||||
### 2. Apply Supabase Migration
|
||||
```bash
|
||||
psql "$SUPABASE_CONNECTION_STRING" -f migrations/supabase/001_init_vector_store.sql
|
||||
```
|
||||
|
||||
### 3. Start Services
|
||||
```bash
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
### 4. Verify
|
||||
```bash
|
||||
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
|
||||
|
||||
1. **Custom MCP Server**: Built custom instead of using OpenMemory MCP to support Supabase + Neo4j
|
||||
2. **Hybrid Storage**: Vector + Graph + Key-Value for optimal query patterns
|
||||
3. **Docker Network**: All services on localai network for container-to-container communication
|
||||
4. **Configuration Module**: Shared config between API and MCP server
|
||||
5. **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
|
||||
|
||||
## Repository Access
|
||||
|
||||
- **URL**: https://git.colsys.tech/klas/t6_mem0_v2
|
||||
- **Branch**: main
|
||||
- **Commits**: 2 (initial + implementation)
|
||||
|
||||
## Files Created
|
||||
|
||||
**Total**: 30 files
|
||||
**Code**: ~3,200 lines
|

|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"messages": [{"role": "user", "content": "I love pizza"}],
|
||||
"user_id": "alice"
|
||||
}'
|
||||
```
|
||||
|
||||
### MCP Server Test
|
||||
Add to Claude Code config:
|
||||
```json
|
||||
{
|
||||
"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:
|
||||
