## FAQ

### Does this server return actual data from my tables?

No, the server is strictly read-only and never returns rows from your tables, focusing instead on the catalog and statistics.

### How is the read-only restriction enforced?

Read-only access is enforced by running every call in its own READ ONLY transaction with a statement timeout.

### Is it safe to use with sensitive data?

Yes, it is designed to minimize data leakage by only accessing the catalog and statistics views rather than table rows.
