Cron Explainer
Parse confusing cron strings inside the agent and show human-readable schedules plus upcoming run times in your timezone.

What is this MCP server?
- Parses cron expressions into plain-language explanations
- Returns next N scheduled fire times with timezone awareness
- Remote streamable-http MCP at cron-explainer.cron-explainer-prod.workers.dev/mcp (v0.1.2)

- Registry version 0.1.2
- 1 remote endpoint: streamable-http at /mcp on Workers dev host

What problem does it solve?
Cron strings are easy to misread and timezone mistakes cause jobs to run at the wrong local time.
Who is it for?
Solo builders configuring scheduled tasks in CI, cron daemons, or cloud workers who want quick validation inside the agent.
Skip if: Teams that need full job orchestration, cron authoring UI, or air-gapped-only tooling without remote HTTP MCP.
What do I get? / Deliverables
Your agent can call the remote MCP to verify a cron line and show the next scheduled runs before you commit infra changes.
- Human-readable explanation of a cron expression
- List of next N scheduled execution instants in the chosen timezone
