Where it talks to
ferrlabs.com (its own)Also ferrflow.com, ferrvault.com, ferrtrack.com, ferrgrowth.com, ferrfleet.com, ferrlens.com — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
what the tools do when called with real credentials

Connect it under the guard; read the third-party hosts first. The code names ferrflow.com, ferrvault.com, ferrtrack.com, ferrgrowth.com, ferrfleet.com, ferrlens.com as well as its own vendor. The guard pins the network to the hosts the honeypot saw.

$vet-skills run --net declared -- npx -y @ferrlabs/mcp

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-12 and scored it 85/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.
