# PostgreSQL MCP Server Project - ✅ COMPLETED
## Completed MCP Server Implementation ✅
- [x] Updated project configuration for MCP server
- [x] Added MCP and PostgreSQL dependencies
- [x] Implemented MCP server core functionality
- [x] Added PostgreSQL connection handling with async connection pooling
- [x] Implemented database tools (query, schema inspection, etc.)
- [x] Added configuration management with environment variables
- [x] Added security and error handling (read-only queries, row limits)
- [x] Created comprehensive test suite
- [x] Added documentation and examples (README.md)
- [x] Created configuration examples (.env.example, config.example.json)
## Completed Enhancement: Query Validation and Optimization ✅
- [x] Implemented comprehensive query validation and optimization suggestions
- [x] Created SQL parser and validator using sqlparse
- [x] Added performance optimization suggestions with specific recommendations
- [x] Implemented security validation with SQL injection detection
- [x] Added index usage analysis and recommendations
- [x] Created query complexity scoring (1-10 scale)
- [x] Added comprehensive tests for validation features
- [x] Integrated validation into existing query tool with real-time feedback
- [x] Created standalone validate_query tool for detailed analysis
- [x] Updated documentation with new features
## Next Steps (Optional Enhancements)
- [ ] Add support for custom query templates
