Cron expressions are notoriously difficult for LLMs to validate perfectly. This MCP uses cron-parser to bring deterministic, programmatic parsing to your AI.

The Superpowers

  • Mathematical Accuracy: It calculates the exact next execution dates without hallucinating constraints.
  • Human Translation: Turns complex expressions into readable schedules instantly.

calculate_next_cron_dates

Use this tool to get the precise mathematical timestamps of when a cron expression will run. Calculates the exact next execution dates for a Cron expression

See how to talk to your AI agent using Cron Expression Calculator.

What are the next 3 execution dates for `0 12 * * 1-5`?

✅ **Next Executions:** 1. `2024-11-18T12:00:00.000Z` 2. `2024-11-19T12:00:00.000Z` 3. `2024-11-20T12:00:00.000Z`

When will the cron `0 0 1 1 *` run next?

✅ **Next Run:** `2025-01-01T00:00:00.000Z` (New Year's Day at midnight).

Validate if `*/15 * * * *` is a structurally sound cron format.

✅ **Status:** Valid. **Description:** This expression executes at every 15th minute.

Yes, it supports all standard cron formats, including step values.
