# Monitor your v0 app

> Add your published v0 app's URL to Lampwick for uptime, SSL, domain and DNS checks without code, and connect v0 to Lampwick over MCP.

Paste your published v0 app's address into Lampwick and it checks the app from outside Vercel, with alerts on your phone. Connect v0 to Lampwick and it can read what Lampwick found, and fix it.

## Where your v0 app runs

When you click **Publish** in the chat header, v0 deploys your app to Vercel at an address ending in `vercel.app`. For your own domain, open **Publish → Customize Domain** and finish the DNS setup in the Vercel dashboard ([v0 docs: deployments](https://v0.app/docs/deployments), [custom domains](https://v0.app/docs/custom-domains), checked 8 Nov 2026).

Monitor your production address, not a preview deployment. On your own domain, its renewal and DNS are your job, and Lampwick watches both.

## Monitor it without code

1. [Create a Lampwick account](https://app.lampwick.dev/signup), confirm your email, and create a project named after your app.
2. Click **Uptime** in the sidebar. Under **Add monitor**, paste your app's address, such as `https://myapp.com`, and click **Add monitor**.
3. The monitor shows **Pending**, then **Up**. SSL, domain and DNS checks are on already.

Every click, plus the status page: [the overview](/for/ai-built-apps/#set-it-up-without-code).

If you've turned on Vercel's protection for your deployment, Lampwick gets a login page instead of your app.

## Connect v0 to Lampwick

MCP is a standard way for an AI agent to use another app's tools. Connected, v0 can look up your monitors, expiry dates and broken links while you chat.

Add Lampwick in v0 ([v0 docs: MCP](https://v0.app/docs/MCP), checked 9 Nov 2026):

1. In the prompt box, open the **+** menu and choose **MCPs**.
2. Add a custom server, not a preset. Name it `lampwick`, with the URL `https://app.lampwick.dev/mcp`.
3. For authentication, choose **OAuth** and save.
4. Lampwick opens. Log in, choose **Read-only (recommended)** and click **Connect**.

Read-only lets v0 look at everything in Lampwick but change nothing. Disconnect it any time under **Account & security** → **Connected apps**. If v0 can't connect this way, use a read-only token instead ([connect with a personal token](/docs/mcp/#token)).

## Check that it works

Ask v0 "Which Lampwick projects can you see?". It should name your project. If it reports an authorization error, remove the server and add it again. Then try:

- "Is my Lampwick monitor up, and when does my SSL certificate expire?"
- "Which broken links did Lampwick's last crawl find? Fix the ones in this app."

Errors inside your app, such as a button that throws, reach Lampwick once you add the [browser error snippet](/docs/browser/). Paste the prompt from your project's **Settings** → **Browser errors** into v0's chat, and it adds one line to your app.
