What we love

✓Official Supabase-built server — covers most of the platform
✓Read-only mode makes exploring schemas safe
✓Branching lets Claude work against a dev clone, not prod

Where it falls short

−Write access can be dangerous without RLS configured
−No visual query builder — you're trusting Claude with SQL
−Realtime channels not fully covered yet
