mcp-nagios-crunchtools
Secure MCP server for Nagios Core monitoring. Query host and service status, acknowledge problems, add comments, schedule forced checks, and read notification history.
Installation
uvx mcp-nagios-crunchtools
Configuration
| Variable | Required | Description |
|---|---|---|
NAGIOS_URL |
Yes | Base URL (e.g., https://nagios.example.com) |
NAGIOS_USER |
Yes | HTTP Basic Auth username |
NAGIOS_PASS |
Yes | HTTP Basic Auth password |
TZ |
Effectively yes | The container's local timezone. Must match the Nagios server's own timezone. |
Why TZ matters
schedule_check submits a start_time to cmd.cgi, which parses it as naive
wall-clock time in the Nagios server's local timezone — there is no offset field
to send. The value is therefore built with time.localtime(), so this container
must run in the same timezone as the Nagios server.
When it does not, forced checks are silently scheduled into the future by the
offset between the two — four hours against an EDT server — and "check now"
appears to do nothing at all. No error is raised. This was a real defect, fixed
in 0.1.2 by switching from gmtime() to localtime(); the timezone assumption
it introduced is why TZ belongs in this table rather than being left implicit.
