About this extension
Muster is the companion browser extension for the Muster fleet-monitoring and honeypot console. It connects to YOUR OWN console over a read-only API token and brings its most useful signals to your toolbar. It never sends anything to UnveilTech or any third party.

What it does:
• Fleet at a glance — machines up, open critical alerts, malicious-hosting count and outdated agents, refreshed live.
• Top CPU and the latest attacker IPs your fleet caught, in real time.
• Desktop notifications for new critical alerts and honeypot surges.
• IP / domain lookup lens — right-click a selection, use the popup, or type “mstr” in the address bar, and get your console’s verdict: is this address attacking your fleet? malicious hosting? a known scanner? what behaviour has been observed?
• Optional attacker-site warning — switch it on and, when you visit a site whose address is attacking your fleet or is flagged as malicious hosting, a banner warns you. Only the page’s host is sent, and only to your own console.

Setup:
1. In your Muster console: Settings ▸ Accounts ▸ edit an account ▸ Extension ▸ create a read-only token.
2. In the extension’s Settings: paste your console URL and the token.

Privacy:
• Read-only — it cannot change anything on your console or your machines.
• It talks only to the console you point it at (your own). No analytics, no phone-home, no data collection.
• The per-account token inherits that account’s scope and is blocked from any owner/operator action.

Requires a running Muster console (https://muster.unveiltech.com).
