Crontab Generator API

MCP Server x402 License: MIT

Convert natural language like 'every Monday at 9am' into valid cron expressions with explanation and next run times. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "crontab-generator": {
      "url": "https://crontab-generator.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl -X POST "https://crontab-generator.api.klymax402.com/api/generate" \
  -H "Content-Type: application/json" \
  -d '{"description":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

utility_generate_crontab

Use this when you need to generate a cron expression from a natural language description like "every Monday at 9am" or "every 5 minutes". Returns the cron expression with validation.

Parameters

NameTypeRequiredDescription
descriptionstringyesNatural language description of the schedule (e.g. 'every Monday at 9am', 'twice a day', 'every 5 minutes')

Example response:

{"expression":"0 9 * * 1","description":"Every Monday at 9:00 AM","nextRuns":["2026-04-14T09:00:00Z","2026-04-21T09:00:00Z"],"confidence":"high"}

When to use: creating new scheduled tasks from user instructions, building crontab configs from plain English, or translating business requirements into cron syntax. Use this BEFORE writing cron entries manually.

Not for: parsing existing cron expressions (use schedule_parse_cron), JSON validation (use data_validate_json), text analysis (use text_count_words).
