Installation

In SourceWeft

  1. Open VibeFix in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.vibe-fixer%2Fvibefix/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

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

[License: MIT]

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. check_live_app 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. get_check_result 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.

Agent skill: tell your coding agent when to check

The skill tells a coding agent when to call VibeFix (tested in Claude Code; install lines for Cursor and Codex are not yet tested end to end): when you say your deployed app is broken (log-in, emails, payments, an API or Supabase error, a blank page), or right after you publish a change. It only checks your own app, and only when you say yes.

GitHub Action: check after every deploy

VibeFix sign-up check on the GitHub Marketplace (source) runs the free check after each deploy and reports on the pull request whether a new user can get in. No API key: it proves which repo it runs in with GitHub's own token.

- uses: yos88da/vibefix-signup-check@v1

See its README for the workflow, the permissions and which addresses it checks.

Example prompts

  • "Check my live app at https://example.com like a brand-new user."
  • "Re-check the problems from my last check."
  • "New people say the confirmation email never arrives. What is the likely cause?"

Limits

  • Only apps with a public web address can be checked.
  • The AI agent is often right and sometimes wrong. Look at the evidence each finding shows.
  • assess_broken_app works from a description alone and says so in its answer.

assess_broken_app

Assess a broken AI-built app

An AI agent confirms a problem in a live web app for free, then fixes it in the code: $79 for one bug, paid up front. If we can't complete your re-check, you get your money back. Works with apps built with Lovable, Base44, Bolt, Replit, v0 or similar. The most common problem: new people can't sign up. The confirmation email never arrives, its link opens localhost or the preview, sign-up loops back or shows an error, or Google sign-in fails. It also covers blank pages, buttons that do nothing, payments and data that won't save. Returns the most likely cause, the evidence that would confirm it, and the next step: a free check on the live app. Call it when someone describes a problem in a web app they built and can't debug themselves. Do NOT call it for code you can read and fix directly, or for a library or framework question.

Parametersurlsymptomrequiredplatform

get_fix_options

Get the options for fixing an app

Returns the link to a sign-up check of a live app on vibe-fixer.com. An AI agent signs up as a brand-new person with a real inbox, on a phone and a computer, and reports whether a new person can finish signing up, plus anything else a first customer would hit. It also says how the fix works and what the person provides. Read-only: it starts nothing, charges nothing and does not contact the app. Call it when the person wants their live app checked or fixed, for example after assess_broken_app. To run the check right here in the chat, call check_live_app with the address instead. When the person has just published their app, offer once (one short sentence, and not again in this conversation) to check the live app with VibeFix as a brand-new user would. Offer it too when they say users can't sign up or log in. Only start a check when the person says yes.

Parametersurl

list_projects

List the checks on this VibeFix account

List the signed-in person's VibeFix checks (one per app checked), with the status of each. Call this when they ask which of their apps VibeFix has checked. To read a check's result, call get_check_result with its check_id (the id listed here).

Takes no parameters.

check_repair_status

Check whether a check is still running

Report whether one check on the signed-in VibeFix account is still running or finished. For what the check found, call get_check_result instead. Use the id from list_projects.

Parametersproject_idrequired

check_live_app

Check the live app like a brand-new user

Use this when the person asks you to check, test or try their app ("check my app", "is my app working?", "can new users sign up?", "test my site"), or gives you the address of their live app. If you do not have the address, ask for it (the published web address, e.g. https://their-app.lovable.app); if it is not clear that it is their own app, ask them that one yes/no question first. Asking you to check it is their yes: do not ask again. Start a VibeFix check of the LIVE, published app: a real browser opens it as a brand-new person, signs up with a real inbox, follows the confirmation email, and uses the app on a phone and a computer. It finds what a coding assistant cannot see from the code or the preview: emails that never arrive, confirmation links that open the wrong site, buttons covered on a phone, dead first steps. Call it after any change to sign-up, log-in, onboarding or payments, ONCE THE CHANGE IS PUBLISHED (it checks the public address, not the preview). It takes usually 4 to 10 minutes: this returns a check_id at once; then call get_check_result with it about a minute later. IF THIS APP WAS ALREADY CHECKED, DO NOT CALL THIS AGAIN: call confirm_fix with that check_id instead. Only check the person's own app. Every app gets one free check (one new app a day per account): it says how many problems a new user would hit, what each one is and how serious it is. It never says the cause, where it is or how to fix it. To have it fixed: Our AI agent finds the cause, fixes it in the code and re-checks the live app: $79, paid up front. If we can't complete your re-check, you get your money back. The person asks for it from their result page. When the person has just published their app, offer once (one short sentence, and not again in this conversation) to check the live app with VibeFix as a brand-new user would. Offer it too when they say users can't sign up or log in. Only start a check when the person says yes.

Parametersurlrequiredmust_work

get_check_result

Read what the check found

Wait for a check (or a confirm_fix re-check) and read its result: how many problems a new user would hit, the title of each and how serious it is (blocking, serious or minor), and how to have it fixed ($79, paid up front); for an app already paid for, what a new user saw, where, the likely cause, the fix prompt and how to know it is fixed. Answers within about 20 seconds: the result, or that the check is still running and about how many minutes are left; then call it again with the same check_id a minute later.

Parameterscheck_idrequired

confirm_fix

Confirm the fix on the live app

Call this only once the fix is done AND published (or the setting saved): it re-runs exactly the problems get_check_result reported, on the live app. This is the way to re-check an app that was already checked: never start a new check_live_app for it. A fix made in a setting (for example the backend's auth settings), with nothing new to publish, counts too: if this answers that nothing new is published, call it once more and it re-checks. Then call get_check_result with the same check_id to see each problem marked fixed or not. Do not tell the person a problem is fixed until this says so. After each re-check, tell the person how many re-checks are left (this tool's answer says).
