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

1. Check. check_live_app starts 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).
2. Read. get_check_result returns 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.
3. Confirm my fix. After you fix something, confirm_fix re-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.

Prices

If we can't complete your re-check, you get your money back.

• "Confirm my fix: re-check the problems from my last check."
• "New people say the confirmation email never arrives. What is the likely cause?"

• The AI agent is often right and sometimes wrong. Look at the evidence each finding shows.
• assess_broken_app works from a description alone and says so in its answer.
