What the app can do
Search and fetch
Use standard search and fetch tools to retrieve API docs, pricing, launch guides, and cron education content inside ChatGPT.
Build schedules
Turn a recurring workflow into a cron expression, retry posture, and webhook threshold recommendation.
Skill layer
MCP prompts and resources act as the first ChatGPT skill surface for schedule design, launch copy, and alert-policy guidance.
Explain cron
Parse a cron expression and preview the next scheduled run times in your target timezone.
Plan alerts
Recommend retries, failure thresholds, and disabled-job escalation for webhook-driven automations.
Why this is the right first version
The current app is intentionally public and read-only. That keeps the MCP server safe to expose, simple to connect, and easy to index.
For actual job creation and account-level actions, the next step is OAuth-backed identity. Until then, this release focuses on planning quality, product discovery, and answer-engine visibility.
That tradeoff is pragmatic: the app becomes usable in ChatGPT now, while the core SimpleCron dashboard and API remain the place for authenticated job management.
