How a cron expression works
A cron expression is five fields separated by spaces. Each field controls one part of the schedule. A *means “every”; a number pins that field to a value. You can also use ranges (1-5), steps (*/15), and lists (1,15).
| Position | Field | Allowed |
|---|---|---|
| * * * * * | Minute | 0–59 |
| * * * * * | Hour | 0–23 |
| * * * * * | Day of month | 1–31 |
| * * * * * | Month | 1–12 |
| * * * * * | Day of week | 0–6 (Sun–Sat) |
Cron + AI: schedule an agent, not just a script
A cron expression only says when— you still need something to run. Traditionally that’s a script on a server you keep alive. Cron AI flips it: instead of hard-coding steps, you give a reasoning AI agent plain-language instructions and a cron cadence, and it does the judgment work each run — reading, deciding, drafting — then emails you the result. Same schedule, but the other end can handle the fuzzy, reasoning-shaped tasks a fixed script can’t.
That’s what Clourou runs: describe a task in plain English, pick a cadence, connect your tools over MCP, and a scheduled agent runs it unattended. Browse ready-to-run routines or read the MCP-native automation playbook.
