Crontab expression MCP.

Natural language to cron expression converter. x402 micropayment.

Cron expression generator API for AI agents. Convert natural language like "every Monday at 9am" or "twice daily" into valid cron expressions with human-readable explanation and next run times. Tools: utility_generate_crontab. Use this when users describe schedules in natural language and you need a cron expression. IMPORTANT: For parsing existing cron expressions, use schedule_parse_cron instead. Returns: {cron, explanation, nextRuns[]}. No API key required — x402 micropayment $0.001/call on Base L2.
