### Description (declared)

# 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

```bash
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 |
| `NAGIOS_COMMENT_AUTHOR` | No | Author recorded on acknowledgements and comments. Defaults to `NAGIOS_USER`. Not a tool parameter. |
| `NAGIOS_CGI_PREFIX` | No | Path under `NAGIOS_URL` where the CGI scripts are served. Defaults to `/nagios/cgi-bin`. Set to `/cgi-bin` for a Nagios served at the web root. A trailing slash is ignored. |
| `NAGIOS_LOG_PATH` | No | Read-only path to `nagios.log`. Enables `nagios_downtime_history` and the planned-work split in `nagios_alert_history`; archivejson.cgi never returns downtime entries. |
| `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.
