What is the Cronalert MCP server?

Most developer tooling work still happens through a UI a human drives. Cronalert MCP server moves it into the conversation instead. Manage CronAlert uptime monitors, check results, and incidents from any MCP client.

The short version

MCP server for CronAlert uptime monitoring. Manage your monitors, check results, and incidents from Claude, Cursor, Windsurf, or any MCP-compatible AI client.

The tools it exposes

The server publishes 10 tools. What each one is for:

  • Read-only — the agent can list and read monitors, check results, and incidents but cannot create, update, or delete anything. Recommended for most agent
  • list_monitors — List all monitors with status and response times
  • create_monitor — Create a new HTTP monitor
  • get_monitor — Get details for a specific monitor
  • update_monitor — Update settings, pause/resume
  • delete_monitor — Permanently delete a monitor
  • get_check_results — Check history with uptime % and response times
  • get_monitor_incidents — Incidents for a specific monitor
  • list_incidents — All active incidents across monitors
  • list_status_pages — Your public status pages

What it needs from you

Configuration is passed through the environment: CRONALERT_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Getting it running

The server ships on npm as cronalert-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

How it compares

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Cronalert's toolset — Read-only, list_monitors, create_monitor and 7 more — is a fair guide to whether it matches your workflow. It is maintained by jaredhobbs; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Cronalert.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Cronalert to MCP-compatible AI assistants such as Claude and Cursor, exposing 10 tools (Read-only, list_monitors, create_monitor, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Cronalert directly.
