SealMyApp security tools

This is a small helper that gives your AI assistant a set of security checks for apps you built with tools like Lovable, Bolt, Cursor, Replit or v0. It can tell you whether a key is safe to show in your app, hand you SQL to check your Supabase rules, and walk you through a pre-launch checklist. It is handy if you are not a developer but you have shipped or are about to ship an app.

What this MCP server does

You ask your AI something like whether a key is safe to put in your frontend. Your AI passes that to this helper. The helper looks at the format of the key and decides if it is meant to be public or if it is a secret. It also has ready-made SQL you can run in Supabase to find tables with weak rules, plus templates for safer rules and a pre-launch checklist. Everything runs on your own computer and makes no network calls.

What you can do with it

• Check whether a key is safe to expose or should be rotated
• Get SQL to audit Row Level Security in your Supabase project
• Generate owner-only policy templates for common tables
• Run a pre-launch security checklist for your builder
• Get instructions for a free ownership-verified scan of your app

Try asking your AI

• “Is a key starting sk_live_ safe in my frontend?”
• “Give me SQL to audit RLS in my Supabase project”
• “Run the pre-launch security checklist for my Lovable app”
• “Show me a safe RLS policy template for a profiles table”

What it gives back to you

You get short, plain answers in the chat. For a key, it tells you whether it is public by design or secret, and what to do next. For Supabase, it gives you SQL you can copy and run, plus how to read the results. For the checklist, it gives you a list of things to check before you launch.
