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).

Self-hosting

Cloudflare Workers + D1 + Hono. The scheduler uses a Cron Trigger (every minute) — available on the free Workers plan.
