The database has to be a defensive boundary again

As AI agents gain live database access, security has to move below the app layer and back into the database itself.

The article highlights Tabularis MCP safeguards: connection-level read-only enforcement, approval gates for writes and heavy reads, and pre-flight EXPLAIN checks.

It also adds local query audit logs and full activity tracing so DBA teams can observe agent behavior and reconstruct incidents.

This matters because agentic SQL can be non-deterministic, long-lived, and risky, making database-level guardrails essential to prevent data loss.
