Getting Supabase MCP running recently was another "oh shit!" moment for me.

Prompting to check the schema is great, but prompting against live data in the DB is amazing! For example:

> When logged in as user me@domain.com, I can't see the Edit button on src/pages/projects/show.tsx. Please use MCP to check if I have the correct permissions in organization_roles. If I do, look at the UI code to see if we are checking it correctly."

Wowzers!
