What you can do with updown.io in Claude and ChatGPT

For developers and site owners who monitor uptime with updown.io.

Check downtime, SSL certificates and domain expiry

The AI gives an overview of all checks: which are down and since when, which have an invalid SSL certificate, and which certificates or domains expire soon.

Report uptime and response times of a site

The AI reads a check's uptime, apdex and timings over a time range. Timings can also be grouped by time or by monitoring location, without uptime.

List the downtimes of a check

The AI lists a check's downtimes with error, start, end and duration. You see which checks had problems and for how long.

Add a check or change an existing one

The AI creates a new check for a URL or heartbeat, or changes the URL, period, alias or alert recipients of a check, pauses it or mutes its alerts.

Changes data

Set up alert recipients and a status page

The AI adds an alert recipient such as an email or Slack webhook, and creates or updates a status page that shows chosen checks.

How do I connect updown.io?

Before you connect

The login page asks for your Updown.io API key.

Find it at updown.io → **Settings → API keys**. The read-only key is enough for every read tool (checks, downtimes, metrics, problems, recipients, status pages); to create/update checks, add recipients or edit status pages, paste the read/write key instead. Your key is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.

In Plugins, install updown.io, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http updown-io https://updown-io.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "updown-io": {
      "url": "https://updown-io.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "updown-io": {
      "type": "http",
      "url": "https://updown-io.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add updown-io --url https://updown-io.usefulapi.io/mcp

codex mcp login updown-io

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://updown-io.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Updown.io API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this updown.io server only. Ask your AI to run updown_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with updown_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with updown_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Create a checkupdown_create_check
Add a new monitoring check. The type (http, https, tcp, tcps, icmp) is inferred from the URL scheme; pass type 'pulse' (and no URL) for a cron/heartbeat check. Each check consumes updown credits while enabled. Requires the read/write API key.
Update a checkupdown_update_check
Change a check's settings — URL, period, alias, string match, recipients, headers, locations — or pause/resume it (enabled) or mute its alerts (mute_until). Only the fields you pass are changed. Caution: URLs returned by a read-only key hide basic-auth credentials; re-sending such a URL erases them. Requires the read/write API key.
Add an alert recipientupdown_add_recipient
Add an alert recipient: an email address, phone number (sms), webhook URL, Slack-compatible incoming-webhook URL, or Microsoft Teams webhook URL. Returns the new (or already-existing) recipient with its id. By default it is selected on ALL existing checks; pass selected=false to add it unattached. Slack/Telegram/Zapier/Statuspage integrations must be set up in the web UI. Requires the read/write API key.
Create a status pageupdown_create_status_page
Create a status page showing the given checks, in order. Returns its token and URL. Requires the read/write API key.
Update a status pageupdown_update_status_page
Change a status page's checks (replaces the list, order respected), name, description, visibility or access key. Only the fields you pass are changed. Requires the read/write API key.

Your usefulapi plan · 4

Usage status (free-tier meter)updown_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featureupdown_request_feature
Tell usefulapi that the user needs something the updown.io tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+updown_upgrade
Get a paid plan for updown.io (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptionupdown_cancel_subscription
Cancel the caller's updown.io Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run updown_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with updown.io in Claude or ChatGPT?

Check downtime, SSL certificates and domain expiry. Report uptime and response times of a site. List the downtimes of a check. Add a check or change an existing one. Set up alert recipients and a status page. See what you can do for the details.

Is this an official updown.io product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by updown.io. The server calls the updown.io API with your own updown.io access, so it sees only the data that your account can see.

Can I connect updown.io to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Updown.io API key. See Before you connect for where to find it.

Do I put my updown.io key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Updown.io API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my updown.io credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the updown.io API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in updown.io.

Can the AI change my updown.io data?

Yes, if you approve it. 5 of the 14 updown.io tools can create or change data. The other 9 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this updown.io server only. Cancel any time: your paid plan then runs to the end of the paid period. Run updown_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run updown_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run updown_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a updown.io tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with updown_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
