VibeFix MCP server

VibeFix: fixed in your code, then tested on your live app.

App broke after you published it? Our AI agent fixes it in your code, then tests your live app again so you see the result yourself. The first check is free.

You built the app with an AI tool, published it, and then something stopped working. Maybe new users can't finish signing up. Maybe the confirmation email never arrives, or checkout throws an error. Maybe you asked your builder's AI to fix it, it said it had, and the problem is still there for your users.

VibeFix starts where your users start. Paste the link to your live app and our AI agent signs up as a brand-new user. It walks through your pages the way a stranger would and sends you a screenshot of the problem it hits. The free check never changes your app.

If you want the problem fixed, the agent goes into your code. It looks for the cause, makes the change in your code, and then opens your live app again to test that the problem is gone. You see the re-check, so you're not taking anyone's word that it's fixed.

What it can work on: sign-up and login, emails that don't arrive or link to the wrong place, payments, API, integration and Supabase errors, and front-end bugs, as long as the cause is in the code.

Today the fix is for apps built with Lovable, or any app whose code is on GitHub.

A paid fix is available on vibe-fixer.com.

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. checkliveapp 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. getcheckresult returns what it found, with evidence.
3. Re-check. confirm_fix re-checks those problems on your live app and marks each one fixed or not.

The free check never changes your app. A full check runs only when you confirm the app is yours; otherwise the check is look-only and does not sign up. Today the fix is for apps built with Lovable, or any app whose code is on GitHub.

Free check, paid fix

The check is free: every app gets one free check. A paid fix is available on vibe-fixer.com.
