Summary
Gives Claude the ability to schedule tasks for execution later, either once or on a recurring basis. Exposes three tools: schedule_task for creating reminders or delayed webhooks with cron-like timing, list_tasks to view pending jobs, and cancel_task to remove scheduled items. Runs as a hosted service on Cloudflare Workers with a one-minute tick granularity. You'd reach for this when your agent needs to trigger notifications (email, Slack, Discord, webhook POST) after a delay or on a schedule, like checking a build status every 10 minutes or sending a weekly summary. Free tier supports 5 active tasks and 1,000 monthly runs. Also ships with self-hosting instructions if you want to run it on your own Workers account.

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.
