Check your live app from Claude Code
Claude Code can use outside tools through MCP. Add VibeFix once, and when something in your live app breaks, Claude Code can ask VibeFix: an AI agent that tests live apps the way a first customer would.
The fastest way: paste this to your agent
Copy this one message and paste it into Claude Code. It does the setup and tells you the one step it can't do for you:
Set up VibeFix for me as an MCP server. First run: claude mcp add --transport http vibefix https://vibe-fixer.com/mcp. Then tell me to restart Claude Code, type /mcp, choose vibefix and press Authenticate, so I can sign in to VibeFix and press Allow. From then on, whenever I say something in my live app is broken, call VibeFix's assess_broken_app with my description and my app's link and show me its answer. If I want it fixed, call get_fix_options and show me the options.
Or do it yourself
- In your terminal, run:
claude mcp add --transport http vibefix https://vibe-fixer.com/mcp - Start Claude Code, type
/mcp, choose vibefix and press Authenticate. A VibeFix window opens: sign in and press Allow.
Prefer plugins? The same server installs as a Claude Code plugin with two commands: claude plugin marketplace add yos88da/vibefix-mcp and then claude plugin install vibefix@vibefix
Use it
Ask in plain words, for example: "My published app's Sign in button does nothing for new visitors. Ask VibeFix what's wrong. My app: https://my-app.example.com"
Claude Code calls VibeFix and shows its answer: the most likely cause, what would confirm it, and what a fix involves. Good things to ask about:
- a button that does nothing
- a blank page after publishing
- a sign-in or sign-up that fails
- data that won't save
- something that worked yesterday and broke after a change
What's free and what isn't
Adding VibeFix and asking it are free. To see what a first customer actually hits, paste your app's link at vibe-fixer.com: an AI agent goes through your live app on a phone and a computer and tells you how many problems it finds, free, no account. Fixes are on a paid plan.
Still stuck?
Paste your app’s link for a free test — no account. Your AI agent goes through it like a first customer, shows you what breaks, then fixes it while you watch.
