Want it fixed? Our AI agent finds the cause, fixes it in your code and re-checks your live app. $79 for one bug, paid up front.

Steps

1. Open your workspace menu at the bottom left and choose Account preferences.
2. Under Builder, scroll to MCP Connections and press Add custom MCP.
3. Name: VibeFix. URL: https://vibe-fixer.com/mcp
4. Authentication: choose OAuth and sign in to VibeFix when asked. If that step fails, choose Not required instead.
5. Press Test, then Test & add.

What to ask in the Base44 chat

• "Use VibeFix: new users can't sign up to my app. What is the likely cause?"
• "Use VibeFix to check my published app at https://your-app.base44.app like a brand-new user."

Asking what is wrong, and getting the link to a free check, works without signing in. Starting a check from the chat needs the VibeFix sign-in.

Right after you publish, the Base44 AI may offer one VibeFix check. It only starts one if you say yes.

An AI agent opens your published app as a brand-new person, signs up with a real inbox and uses the app on a phone and a computer. The free check shows how many problems a new user would hit, plus one screenshot. Our AI agent can find the cause, fix it in your code and re-check your live app: $79 for one bug, paid up front. The free check never changes your app.

Only check an app that is yours.

Notes

• Base44 says MCP connections are only available in the editor chat while you build, not inside your published app.
• Base44 allows up to 20 MCP servers per account.
