What specific types of monitoring can I manage with this skill?

This skill integrates with the CronAlert API to monitor the health of websites, APIs, and cron jobs. It allows you to create heartbeat pings for background tasks and TCP checks for databases, alerting you instantly if a service fails or a scheduled job is late.

What are the technical requirements for using this skill?

This skill requires an active CronAlert account and an API key. It is designed to interface with AI agents that support the Model Context Protocol (MCP), allowing the agent to communicate directly with CronAlert's infrastructure.

Can I migrate my existing monitoring setup from another provider using this skill?

Yes, the skill includes specialized tools for bulk migration, allowing you to transition monitoring suites from providers like UptimeRobot, Pingdom, or Better Stack into CronAlert with minimal manual effort.

Are there any limitations on the types of checks or account tiers supported?

While highly versatile, the skill does not support ICMP ping or UDP checks, and HTTP monitors cannot target bare IP addresses. Additionally, users on CronAlert's free plan are limited to 3-minute check intervals and read-only API access.

How does the skill handle alerts during scheduled server maintenance?

The skill allows you to pause monitors or schedule maintenance windows directly through your AI agent. This prevents false positive alerts during planned deployments or server updates.

Example session with this skill installed

Create a new HTTP monitor for my production API at https://api.acme.corp/v1/health. It should return a 200 and the body must contain the string "status":"ok".

Read your context and instructions
Compiled the cronalert uptime monitoring

I have created the new HTTP monitor for your production API.

Monitor Created: API Health Check

Property	Value
Name	API Health Check
URL	`https://api.acme.corp/v1/health`
Type	http
Expected Status	200
Keyword Match	contains `"status":"ok"`
Status	unknown (first check pending)
Monitor ID	`mon_8f2d91bc`

Next steps

Wait 3 minutes for the first check to complete, then ask me to check the status.

About this skill

You can't fix what you can't see. When services go down or cron jobs fail silently, your users find out before you do. This skill provides direct control over CronAlert monitoring to observe, triage, and manage your infrastructure availability.

What it does

Monitor URLs and APIs by checking status codes and asserting response content.
Track cron jobs using heartbeat pings that alert when scheduled tasks or backups are late.
Verify TCP services such as databases, Redis, or SMTP servers via port-level connectivity checks.
Triage outages by analyzing recent check results, error messages, and response time trends.
Manage maintenance by pausing monitors or scheduling maintenance windows during deploys.
Bulk migration from services like UptimeRobot, Pingdom, and Better Stack.

How it works

Connect the cronalert-mcp server using your API key from the CronAlert dashboard.
Configure monitors for your services by specifying URLs, expected status codes, or heartbeat intervals.
Analyze incidents by listing active failures and inspecting the last 10 check results for root causes.
Update status pages with investigation notes or resolution details when an incident is active.

Frameworks & tools

This skill interfaces with the cronalert-mcp server. It supports monitoring for any web service, TCP-accessible database, or scheduled task (Python, Node.js, Bash).

Why this beats prompting it yourself

Generic prompts often struggle with the nuances of uptime monitoring, such as Cloudflare's restrictions on bare IP addresses or port 25. This skill understands specific CronAlert plan limits and ensures heartbeat grace periods are calculated correctly to avoid false positives.

Use cases

Automate the creation of uptime checks immediately after a new service deployment.
Investigate why a service is failing by pulling status codes and keyword match errors.
Sync monitoring state with deployment pipelines using maintenance windows.
Migrate dozens of monitors from legacy providers using a single export file.

Known limitations

Does not support ICMP ping or UDP checks. HTTP monitors cannot target bare IP addresses. Free plan accounts are limited to read-only API access and 3-minute check intervals.
