Coverage

Tested

Before you give it your token

It will ask for
LOKI_PASSWORDLOKI_TOKENConfiguration, not credentials: LOKI_DEBUG, LOKI_HEADERS, LOKI_MAX_RETRIES, LOKI_TENANT_ID, LOKI_TIMEOUT, LOKI_URL, LOKI_USERNAME
Where it talks to
no vendor host named in the codeAlso unconfigured.invalid — 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 with a scoped credential, under the guard, and read the third-party hosts first. The code names unconfigured.invalid as well as its own vendor. The guard injects LOKI_PASSWORD, LOKI_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

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

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 93/100 (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.
