Cron Parser
Let your coding agent parse, validate, and explain cron expressions while you wire Workers cron triggers, job schedulers, or admin UIs.
Overview
io.github.lazymac2x/cron-parser is a MCP server for the Build phase that exposes cron schedule parsing and validation to your agent over streamable-http.
What is this MCP server?
- Remote streamable-http MCP at api.lazy-mac.com/cron-parser/mcp (no local daemon)
- Cloudflare Workers–backed cron-parser utility for agent-driven schedule design
- Version 1.0.0 server manifest aligned with MCP 2025-09-29 schema
- Source and API repo: github.com/lazymac2x/cron-parser-api
- Fits Claude Code, Cursor, and Codex workflows that need human-readable cron explanations
- Server version 1.0.0 per MCP manifest
- 1 remote streamable-http endpoint
- Hosted on Cloudflare Workers (lazy-mac.com API)
What problem does it solve?
Cron strings are easy to get wrong, and guessing schedule behavior wastes time when you are wiring Workers crons or background jobs alone.
Who is it for?
Solo builders using Claude Code or Cursor who add scheduled Workers, webhooks, or queue jobs and want the agent to sanity-check cron expressions inline.
Skip if: Teams that need enterprise job orchestration, cluster-wide cron management, or monitoring of live job failures without any agent in the loop.
What do I get? / Deliverables
Your agent can query cron-parser over MCP so schedules are validated and explained before you commit triggers to code or infrastructure.
- Validated cron expressions aligned with your worker or job configuration
- Agent-readable explanations of schedule fields and intended run behavior
- Fewer bad deploys caused by malformed cron strings in code or wrangler config
Recommended MCP Servers
Journey fit
Cron semantics sit on the integration boundary between app code and scheduled execution, which solo builders configure during the build phase. Integrations is the canonical shelf because the server exposes schedule parsing as a tool your agent calls while hooking APIs, workers, and automation—not as a one-off research task.
How it compares
Lightweight cron DSL helper over MCP, not a full scheduler like Kubernetes CronJob or a hosted cron SaaS dashboard.
Common Questions / FAQ
Who is io.github.lazymac2x/cron-parser for?
Indie developers and agent users who configure cron triggers on Cloudflare Workers or similar APIs and want parsing help inside the coding session.
When should I use io.github.lazymac2x/cron-parser?
Use it while building integrations—when you are defining schedules, debugging invalid cron strings, or documenting run times for ops-minded teammates.
How do I add io.github.lazymac2x/cron-parser to my agent?
Register the remote MCP URL https://api.lazy-mac.com/cron-parser/mcp as a streamable-http server in Claude Code, Cursor, or another MCP-capable client, then invoke its tools from the agent.
