Add VibeFix to Cursor in 1 minute

To add VibeFix to Cursor, press Add to Cursor on the tools page and confirm in Cursor. Or add https://vibe-fixer.com/mcp as a url under mcpServers in ~/.cursor/mcp.json.

Steps

1. Open vibe-fixer.com/tools and press Add to Cursor.
2. Cursor opens and asks you to confirm. Nothing to paste.
3. Sign in to VibeFix when Cursor asks, so it can start a check of your live app.

By hand instead: create ~/.cursor/mcp.json (every project) or .cursor/mcp.json (one project) with:

• {"mcpServers": {"vibefix": {"url": "https://vibe-fixer.com/mcp"}}}

What to ask in Cursor

• "Use VibeFix: Google sign-in on my live app fails but works locally. What is the likely cause?"
• "Use VibeFix to check my app at https://your-app.com like a brand-new user."

Right after you publish, Cursor's AI may offer one VibeFix check. It only starts one if you say yes.

What the check gives you

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. The full details and the fix prompt for every problem, plus 3 re-checks, are $9 for that app. VibeFix only checks; it never changes your app.

Only check an app that is yours.
