Ask AI

ask anything. change nothing.

It reads your schema, writes the SQL, and shows you every query it ran. Modifying your data isn’t a setting it respects — it’s a thing it cannot do.

CubbyDB with the Ask AI panel open beside the recipes grid: the assistant answers how many recipes contain beef, shows the SELECT it ran, and previews a joined export with a Download CSV button.

Read-only

It can't write. By construction, not by policy.

Asking it to change something isn't refused by a prompt that could be talked around. There is no write path for it to reach.

  • No write methods exposed to the tool layer at all
  • One SELECT-family statement, checked against an allowlist
  • Run in a READ ONLY transaction, always rolled back
