# VibeFix > An AI agent that tests a web app like a first customer, then fixes what is broken, whatever > made it (AI app builders such as Lovable, Base44, v0, Bolt or Replit, AI code editors such as > Cursor, or hand-written code), for the people who built it and cannot debug it. Paste the > app's link: the free test goes through sign-up, the main thing the app does and checkout on a > phone and a computer, and shows what breaks. The fix is approved by the owner before it lands. The free test takes about five minutes and needs no account. The result is a grade from A to F, a short list of what a first customer would hit, and screenshots of what the AI agent saw, with a report link that can be emailed. The full diagnosis, the fix, and a re-test every week and after each new publish come with a plan. VibeFix is for non-developers. It is not a code assistant, an IDE plugin, or a chatbot that explains code: it does the repair and hands back a reviewable change. No repository is needed if the app lives in a builder: the AI agent opens the app, the owner signs in to the builder in a browser beside the chat, and the agent works inside it while they watch. If the code is on GitHub, the fix can arrive as a pull request instead. ## Pricing The first test of an app is free. Fixing takes a plan: plans are monthly balances of credits; a repair spends credits according to how much work it took. - $19 a month: 250 credits. - $49 a month: 700 credits. - $149 a month: 2,500 credits. - Top-up: 120 credits for $10; purchased credits do not expire. ## For agents - [MCP server card](https://vibe-fixer.com/.well-known/mcp.json): machine-readable description of the MCP endpoint. - [MCP endpoint](https://vibe-fixer.com/mcp): Streamable HTTP, POST only. Protocol 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26; the handshake-era versions are answered with initialize. - `assess_broken_app`: available without credentials. Give it a described symptom and it returns the most likely cause, the evidence that would confirm it, and what a fix involves. It reads the description only — no code and no access to the app — and says so. - `get_fix_options`: available without credentials. Returns the link that starts a live test of the app, the plans and one-time pack with prices, and what the person provides. Read-only. - `list_projects` and `check_repair_status`: read-only, for a VibeFix account connected by OAuth sign-in (scope repairs:read; metadata at https://vibe-fixer.com/.well-known/oauth-protected-resource). They list the account's projects and the state of each repair; they cannot start or change one. - [Add it to your AI tool](https://vibe-fixer.com/tools): Cursor, Replit, Lovable and Claude, one step each. ## Pages - [Home](https://vibe-fixer.com/): what it does and how to start. - [Pricing](https://vibe-fixer.com/pricing): credits and plans. - [Real repairs](https://vibe-fixer.com/fixes): broken AI-built apps, what was actually wrong, and the fix. - [Use it inside your AI tool](https://vibe-fixer.com/tools): the MCP address and one-step installs. - [Fix guides](https://vibe-fixer.com/guides): what to do when an AI-built app breaks, by symptom. - [Is a secret key or admin page visible on my live app?
