AgentCron

---

What it does

Agents can't sleep, wait, or run on a schedule. AgentCron gives them time:

• ⏰ Remind later — "Notify me in 2 hours to review the PR."
• 🔁 Recurring — "Email me a summary every weekday at 9am."
• 🪝 Delayed webhook — "POST this URL in 30 minutes to resume the workflow."
• 🔍 Poll — "Every 10 minutes, hit the status webhook."

A scheduled task either notifies you (email / Slack / Discord / webhook) or POSTs to a webhook at the chosen time. One-off or recurring.

🔒 Read-only by design. AgentCron only runs the tasks your agent schedules. No access to your inbox, files, or accounts.

Tools

Tool	Purpose
schedule_task	Schedule a notify or webhook task. Timing: in_seconds or run_at (ISO 8601 UTC); add repeat_every_seconds to recur.
list_tasks	List pending and recent tasks.
cancel_task	Cancel a pending task by id.

Pricing

• Free — 5 active tasks, runs as often as every 5 min, 1,000 runs/month.
• Pro — $9/mo or $90/yr — 200 tasks, 60s min interval, 100,000 runs/month.

Timing is best-effort on a 1-minute tick (no sub-minute scheduling).
