# MCP Server Enhancement Issues

## Priority 1: Core Infrastructure

### Issue 1: Database Integration with Existing PostgreSQL Setup
**Labels**: `enhancement`, `database`, `priority-high`

#### Description
Currently, the MCP server uses in-memory storage for transactions. We need to integrate it with the existing PostgreSQL database.

#### Tasks
- [ ] Add SQLAlchemy to requirements.txt
- [ ] Create database models that align with existing Prisma schema
- [ ] Implement database connection handling
- [ ] Convert in-memory operations to database operations
- [ ] Add database migration system
- [ ] Add connection error handling
- [ ] Add database connection pooling

#### Technical Details
- Use existing PostgreSQL setup from docker-compose.yml
- Align with existing Prisma schema structure
- Implement proper connection closing and resource cleanup

#### Dependencies
- SQLAlchemy
- alembic (for migrations)
- psycopg2-binary

**Estimated time**: 3-4 days
