Assessment: Cronitor's MCP server is one of the most carefully documented we've read, with strict input schemas, summary modes, typed error codes and clear advice on secrets in monitor output. It has 71 tools, publishes no changelog, and its terms and privacy pages are closed to crawlers, so data handling couldn't be checked.

## Before you call it

1. Start with list_monitors and list_issues in summary mode
2. Ask the user before expanding event messages, command output or request bodies
3. On a rate-limit error, wait retry_after_seconds
4. Over the plan's monitor limit, new monitors are saved but disabled

## Connect

```bash
claude mcp add cronitor --transport http https://cronitor.io/mcp
