Scansca Technology Stack

This document outlines the recommended technology stack for implementing Scansca as an MCP server for database intelligence.

Core Components

Backend Services

Component	Technology	Rationale
MCP Server	Go + mark3labs/mcp-go	Native MCP protocol support through official SDK
API Server	Go (Gin)	High-performance, lightweight HTTP framework with middleware support
State Management	Go + Viper	Flexible configuration management with support for multiple formats
Task Scheduling	robfig/cron	Reliable cron-based job scheduling in Go

Database Connectors

Component	Technology	Rationale
PostgreSQL Connector	pgx/v5	High-performance, feature-rich PostgreSQL driver
MySQL/MariaDB Connector	go-sql-driver/mysql	Official MySQL driver with broad compatibility
SQLite Connector	mattn/go-sqlite3	CGo-based SQLite driver with full feature support
DynamoDB Connector	aws-sdk-go	Official AWS SDK for DynamoDB access

Core Storage

Component	Technology	Rationale
Configuration Storage	JSON/YAML + Viper	Flexible, human-readable configuration format
Metadata Storage	PostgreSQL	Robust relational database for structured metadata
Metrics Storage	Prometheus	Time-series database for performance metrics

Infrastructure

Deployment

Component	Technology	Rationale
Containerization	Docker	Portable, isolated runtime environment
Orchestration	Kubernetes (optional)	Scalable deployment for production environments
Configuration	Kustomize	Kubernetes-native configuration management
CI/CD	GitHub Actions	Integrated build and deployment pipeline

Observability

Component	Technology	Rationale
Logging	zerolog	Structured, high-performance logging for Go
Metrics	Prometheus	Industry-standard metrics collection and alerting
Tracing	OpenTelemetry	Distributed tracing for request flows
Visualization	Grafana	Dashboards for logs, metrics, and traces

Security

Component	Technology	Rationale
Authentication	JWT	Stateless authentication for API access
Authorization	RBAC	Role-based access control for database operations
Secret Management	Environment variables + Vault (prod)	Secure secrets management
TLS	Let's Encrypt	Automated certificate management

Development Tools

Component	Technology	Rationale
API Documentation	OpenAPI/Swagger	Industry standard API documentation
Testing	Go testing framework + testify	Comprehensive test coverage
Linting	golangci-lint	Enforces code quality and consistency
Database Migrations	golang-migrate	Version-controlled schema changes

Development Setup Requirements

1. Go 1.22 or higher
2. Docker and Docker Compose
3. Git
4. IDE with Go support (VSCode with Go extension recommended)

Production Deployment Considerations

• Use separate database instances for Scansca metadata and monitored databases
• Implement proper backup and disaster recovery procedures
• Configure appropriate resource limits for database connections
• Use a reverse proxy (Nginx, Traefik) for TLS termination and load balancing
• Implement monitoring and alerting for system health
