Rank a SIEM or EDR alert queue before a human opens it. Scores each alert likely true positive or likely false positive from its own fields — rule, process, command line, parent, user — with a calibrated confidence, so the sure ones disposition themselves and an analyst starts at the top of the rest. Defensive triage only. Use on "which of these are worth opening", "tune out the noise", "rank the queue".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Triage an alert queue before anyone opens it
Noise is usually obvious from the alert record alone: a service installed by
`msiexec.exe` as SYSTEM is a package installer; the same rule on a service
pointing into a public directory is not. `classifier.dev` scores that over a
whole queue in one call, no key. It orders work for a defender; it closes
nothing, touches no host.
## When not to use it
- As the detection itself. It reads the alert record, not telemetry.
- When the answer needs context the record lacks — asset criticality, the
change ticket, what the parent did an hour ago. Enrich first, classify after.
- On fewer than about twenty alerts. Read them.
## 1. Flatten each alert
One line per alert, same fields in the same order every time. Stable order is
what makes scores comparable across a queue.
rule=NAME | proc=IMAGE | cmd=COMMAND LINE | parent=PARENT IMAGE | user=ACCOUNT
Send no host names or addresses unless the rule needs one.
Smoke-test one line with the GET form, which answers the bare label (add
`--data-urlencode "verbose=1"` for JSON with scores):
```
curl -s -G https://classifier.dev/ \

How to install
mdr add mrmps/classifier-dev/soc-alert-triage@sha256:8e8792d04cd21c61The line at the top of this page pins the label git:20260919.33ae531, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
