VibeFix: an AI agent that signs up to your live app like a new person
VibeFix is an AI agent that signs up to your live, published app like a brand-new person, with a real inbox, on a phone and a computer, and shows what breaks. For each problem it confirms, it tells your AI tool what to fix: where it is, the likely cause, and how you'll know it's fixed.
Every app gets one free check. This repository is the MCP connection for it: add the server to your AI tool, then ask it to check your live app.
- Endpoint:
https://vibe-fixer.com/mcp - Transport: Streamable HTTP
- Authentication: two tools need no sign-in; five use OAuth sign-in to your VibeFix account (the client is prompted when you call one)
- Website: vibe-fixer.com
- Server card:
/.well-known/mcp.json - Registry name:
com.vibe-fixer/vibefix
What it does
- Check.
check_live_appstarts a check of your published app. It signs up as a brand-new person with a real inbox, follows the confirmation email, and uses the app on a phone and a computer. Every app gets one free check (one new app a day per account). - Read.
get_check_resultreturns what it found, with evidence. For each problem it confirms, it says where it is, the likely cause, and how you'll know it's fixed. - Confirm my fix. After you fix something,
confirm_fixre-checks those problems on your live app and marks each one fixed or not.
VibeFix checks your app; it never changes it. A full check runs only when you confirm the app is yours; otherwise the check is look-only and does not sign up.

- "New people say the confirmation email never arrives. What is the likely cause?"
