For immediate release
TORONTO, ON, November 12, 2026. JillionDB today launched a review step for the database changes that AI coding agents make. Instead of writing a migration straight into a project, an agent sends the change to JillionDB. A person sees it drawn on their schema, with every step marked safe, caution or destructive and a reason anyone can read, then approves, edits or rejects it. Only then does the agent receive the migration, for PostgreSQL, MySQL or SQLite.
Coding agents now write a growing share of new software, including the migrations that change live databases. Some of those changes are quietly dangerous. A rename written as a drop and an add deletes a column’s data. A shorter text limit cuts values off. A new required column fails on a table that already has rows. In a code diff, each of these looks routine, and each is easy to approve without a real look.
JillionDB connects to agents over the Model Context Protocol (MCP), the open standard AI tools use to reach other services, with one command and one key. The agent reads the current schema, proposes its change and waits. The proposal arrives on a visual canvas of the schema, and every step carries its risk and the reason for it. Once approved, the agent receives the exact forward and rollback SQL, which the team’s own tools apply. JillionDB never runs SQL against anyone’s database.
Also launching today is the JillionDB bridge, an open-source command that compares the real database with the reviewed schema. Run with npx jilliondb push on a laptop, inside a private network or in a CI pipeline, it reads table definitions where the database lives and sends only those. The database password never leaves the machine, and JillionDB never connects in. With --fail-on-drift, it stops a build the moment the database and the reviewed schema disagree.
Agents are remarkably good at writing a migration and remarkably bad at knowing what it will cost you. I wanted the moment before a database change to feel like a good code review: you see exactly what will happen, in words you understand, and nothing moves until you say so.
Availability
