Your AI Needs Boundaries: Building a Secure Read-Only Oracle Environment for MCP Server

The Problem:

SQLcl’s MCP Server enables powerful AI-assisted database work but exposes all saved connections by default, with no ability to filter production from development or restrict which connections AI can access. 

The Solution: 

A production-tested security architecture using: 

• Dedicated read-only AI user
• Database logon trigger for connection restriction
• Comprehensive audit trail
• Complete implementation SQL (copy-paste ready)

Why Now: 

MCP adoption is accelerating, but security guidance is minimal. Organisations need practical, tested solutions, not just theory.
