Ask your AI assistant what went down overnight.
UpWatchr ships an MCP server. Claude, Cursor, VS Code and other assistants can read your watchlist, your uptime and every status change - and, once you allow it, add, pause or re-check a site. Free, local, and off until you turn it on.
What went down while I was asleep?
Two things. staging-api was offline from 03:12 to 03:40 - 28 minutes of 502s. The NAS admin panel timed out twice and recovered both times. Everything else stayed up.
The question the dashboard can't answer
MCP - the Model Context Protocol - is an open standard for letting an AI assistant use a tool. An MCP server publishes a list of things it can do, and the assistant calls them when your request needs one. It works in Claude, Cursor, VS Code and the rest, and keeps working when you switch.
UpWatchr's dashboard shows you what is up right now and a 24-hour grid. "What went down while I was asleep, and for how long?" is a different question - the answer is in the stream of status changes UpWatchr records, and the dashboard has no view of it. An assistant can read that stream and answer in a sentence.
What you can ask
- "Which of my sites are down right now?"
- "What changed since this morning?"
- "How much downtime did the shop have in the last 24 hours?"
- "Is the billing API up? Check it now."
- "Start watching https://status.example.com every 30 seconds."
- "Pause the staging checks - we're redeploying."
- "If the shop goes down, would I hear about it on Telegram?"
What the assistant can do
Read
How many sites are online, offline or paused; the watchlist with each site's state; one site in full - its request, interval and recent changes; every status change in a time window; and the last 24 hours of uptime from the dashboard's own heatmap.
Alerts, without the secrets
Which notification channels are on and roughly where a message would land - enough to answer "would this reach me?", never the token or password behind it.
Change
Add a site, edit its name, URL, interval, timeout, method or expected status codes, pause or resume it, or run a check now. All of it behind a second switch that starts off.
Show you
Bring UpWatchr forward with a site selected. And removing a site only ever raises UpWatchr's own confirmation - the click is yours.
Safe by default
- Off until you turn it on. A fresh install does not listen for assistants. While the switch is off, every request is refused with a message that names the setting, so the assistant can tell you why.
- Read-only until you allow more. Let it change my sites is a second switch, also off. Even "check now" sits behind it: it stores nothing, but it sends a real request to somebody's server from your IP, and a read-only setup did not agree to that.
- Removing always asks. Removing a site throws away its history and there is no undo, so the assistant can only raise the confirmation. You answer it.
- Credentials never leave. Header values - usually the API key a monitored endpoint needs - basic-auth passwords, the SMTP password, the Telegram bot token, the full webhook URL and the full email recipient are never returned. The assistant sees header names and whether a site uses auth, nothing more.
- Never off your PC. The connection listens on
127.0.0.1only and every request carries a token generated on your machine. Reset it in Settings to cut off anything you connected earlier. Every switch applies at once, with no restart.
Connect an assistant
- Install UpWatchr 2026.9.3 or later - it updates itself if you already have it.
- Open Settings > AI assistants and tick Let AI assistants connect to UpWatchr. Tick Let it change my sites too if you want it to add, pause or check sites.
- Press Connect an assistant, pick yours and press Connect. Restart the assistant, then ask it: which of my sites are down?
Connect an assistant picks the shortest safe route for each one. For Claude Desktop, Cursor, VS Code, Windsurf and Gemini CLI, UpWatchr adds itself to the assistant's settings file - everything already there is kept, a copy is saved first, and removing it again is one button. Claude Code gets a one-line command, and Codex CLI, Antigravity and anything else get the exact steps. Assistants it finds on your PC are listed first.
UpWatchr does not have to be open: the assistant's first request starts it, as a normal window. Turning the switch on places a small upwatchr-mcp.exe in UpWatchr's install folder, and that is what the assistant launches - it always finds the version you have installed, so an update never breaks your setup. ChatGPT and Claude in the browser cannot connect: they reach MCP servers from their own servers, and UpWatchr's runs on your machine.
What it deliberately does not do
- Configure your alert channels or the status page password - those are credentials, and they stay in Settings.
- Reset your statistics - destructive, with no undo.
- Remove a site without asking you, ever.
Common questions
What is an MCP server?
MCP (Model Context Protocol) is an open standard that lets an AI assistant use outside tools. UpWatchr's MCP server gives an assistant a set of actions - read the watchlist, the uptime and the history of status changes, and, if you allow it, add or re-check a site - that it calls when you ask. Most AI clients and coding agents support it.
Is it free?
Yes. The MCP server is part of UpWatchr, which is free: no paid tier, no account and no limit on the number of sites.
Can the assistant remove my sites?
Not on its own. A remove request brings UpWatchr forward with the site selected and shows the same confirmation the row menu does. You answer it; the assistant cannot. Removing a site discards its history, so that decision stays yours.
Does the AI see my API keys or passwords?
No. Header values, basic-auth passwords, the SMTP password, the Telegram bot token, the full webhook URL and the full email recipient are never returned. The assistant sees header names and whether a site uses authentication - enough to reason about a check, never the credential itself.
Does UpWatchr have to be running?
No. If UpWatchr is closed, the assistant's first request starts it as a normal window. Its history only covers the time it was running, though - UpWatchr monitors while your PC and the app are on.
Which assistants can connect?
Any MCP client that runs on your PC. UpWatchr sets up Claude Desktop, Cursor, VS Code, Windsurf and Gemini CLI for you, gives Claude Code a one-line command, and shows Codex CLI, Antigravity and anything else the exact steps. ChatGPT and Claude in the browser cannot connect: they reach MCP servers from their own servers, and UpWatchr's runs on your machine.
