What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

What the honeypot saw
no credential files read · no network
What we could not test
use of the skill by an agent

Connect it with a scoped credential, under the guard. It asks for ARKOVA_ACCESS_TOKEN, ARKOVA_API_KEY, ARKOVA_WEBHOOK_SECRET_DIR, USER_ACCESS_TOKEN and talks to arkova.ai. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.

$vet-skills run --secrets ARKOVA_ACCESS_TOKEN=arkova.ai,ARKOVA_API_KEY=arkova.ai,ARKOVA_WEBHOOK_SECRET_DIR=arkova.ai,USER_ACCESS_TOKEN=arkova.ai -- npx -y arkova-mcp-server

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 (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-11 and scored it 88/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
