Cloud SQL for PostgreSQL: Qwik Start

Why it matters

Relational systems remain authoritative sources for many agent workflows. Tool access must preserve transaction, identity, and query boundaries rather than treating the database as prompt context.

What to practise

Create a Cloud SQL instance, connect with a client, load data, and run SQL while observing the network and credential steps required for access.

How it fits

Use the exercise to reason about the governed database and MCP boundaries in subsection 3.2, including least privilege and separation between retrieval and mutation.
