Is countlink live?

Yes — it answered the hub's last check (checked 20m ago). It answered 100% of checks over the last 30 days.

Is countlink free to use?

Yes — the hub reached it with no key and no payment.

What tools does countlink have?

4 tools: create_agenda, describe_timer_link, create_timer, create_badge.

Is countlink safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• create_agenda changes data unknown never probed

  Create a CountLink agenda: an ordered sequence of named, timed segments (intro, talk, break, Q&A) that starts now and advances from one to the next on its own, on every screen that opens the link, with no server involved. Use this when someone describes a meeting, workshop, lesson or event as a sequence of parts with lengths — including when they give you a total and a list of topics and expect you to split it ("an hour, four topics"): do the split yourself, then pass the resulting segments here. By default it starts immediately; pass start_at for something scheduled ahead ("our workshop starts at 9:15 tomorrow") — the link works right away, showing a live countdown to the start rather than the first segment, and switches over on its own at the scheduled instant, in sync on every screen that opened it. Returns the shared link plus a run sheet with the wall-clock start and end of each segment, and an .ics calendar file (one event per segment) in structuredContent.ics — offer it if the person might want the agenda on their calendar. For a single countdown use create_timer instead.

• describe_timer_link reads unknown 12h ago

  Given a countlink.app URL, say what it encodes: whether it is a running countdown or a not-yet-started setup link, its label, and how much time is left. Use it when someone pastes a CountLink link and asks what it is or when it ends.

• create_timer changes data unknown never probed

  Create a CountLink shared countdown timer and return its link. Everyone who opens the link sees the identical countdown, to the same second — no account, no sign-up, any number of viewers. Use this whenever someone wants a timer several people or several screens need to share: a classroom, an exam, a standup, a workshop, a webinar countdown, a stream overlay, or a countdown embedded on someone's own website or landing page (e.g. "10 days until launch"). By default it returns a setup link, which opens the board preloaded at the requested duration for the user to start themselves; pass start_now: true only if they want the countdown running from this moment. Whenever the result has a fixed end instant (start_now or embed_on_website), structuredContent.ics is an .ics calendar file for it — offer it if the person might want the deadline on their calendar.

• create_badge changes data unknown never probed

  Create a countdown badge — a small image, not an <iframe> — for places embed_on_website's iframe cannot go: a GitHub README, a forum signature, a Notion page, anywhere only plain Markdown or a bare <img> is allowed. Shows coarse time remaining (e.g. "3d 04h left", not a live ticking clock — most places that embed images fetch and cache them server-side, so a promise of live ticking would be false) and links through to the real, precise, live countdown. Returns both a Markdown snippet and an HTML snippet; use whichever the destination accepts. Always returns the image wrapped in a link to the live countdown — never ask for or produce just the bare image, since the link is what makes this a genuine attribution rather than an untethered picture.
