A remote MCP server that lets an assistant check whether any public website is down, review uptime history, and inspect HTTPS certificate expiry.
What you can do
Check any public site's live up/down status from an independent server, with status code, latency, resolved IP, redirect target and user report counts, plus a second-region view where available. List monitored sites currently confirmed down, optionally filtered by category. Retrieve uptime percentages, outage lists and last-down times for monitored sites over up to 7 days. Read a public domain's HTTPS certificate expiry date, days remaining and issuer. Browse the 634 monitored sites across 17 categories by category or text query.
When to use it
Useful when you need to confirm whether a site outage is real or local, to check recent uptime and outage history of a monitored site, or to see when a domain's TLS certificate expires.
Requirements
A remote streamable HTTP endpoint; no local runtime, account, API key or environment variables are declared. Network access to the service is needed.
Before you install
Queries are sent to a third-party service, which sees the domains you check. Results are limited to the service's own vantage points and monitored site list, so they are not a full monitoring replacement. No write, payment or credential actions are described.
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.downforjustmeoreveryone%2Fis-it-down/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.
Live up/down check of any public website from an independent server (Singapore; Boston for sites that geo-block Singapore). Returns a one-sentence verdict plus status code, latency, resolved IP, redirect target, the view from the other region when available, and how many users reported problems in the last hour. Results are cached 30 s per domain.
Parametersdomainrequired
list_outages
Which monitored sites are down right now
Lists the monitored sites (634 across 17 categories) that are confirmed down right now: two consecutive failed checks from their home region and no other region seeing them up in the last 15 minutes. Optional category filter.
Parameterscategory
site_history
Uptime and recent incidents of a monitored site
Uptime percentage over 24 h and over the requested window (up to 7 days), the list of outages in that window, when the site was last seen down, the current state and user-report counts. Only for monitored sites (see list_monitored_sites); use check_site for anything else.
Parametersdaysdomainrequired
check_certificate
TLS certificate expiry of a website
Reads the HTTPS certificate of a public domain and reports days until expiry, the expiry date and the issuer.
Parametersdomainrequired
list_monitored_sites
Sites with stored history
The 634 sites checked every 5 minutes, grouped in 17 categories. Without arguments returns the category list with counts; filter by category or a text query to get domains (at most 200 per call).

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
