Coverage

Server started and answered tools/list.
Tested
MCP initialize and tools/list · every tool description, for hidden instructions · every file read, file written and host contacted by what ran
Not tested
what the tools do when called with real credentials

Before you give it your token

It will ask for
ALIASFLEET_API_KEYALIASFLEET_DEV_NO_AUTHConfiguration, not credentials: ALIASFLEET_API_BASE_URL, ALIASFLEET_MOCK
Where it talks to
aliasfleet.com (its own)
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. It asks for ALIASFLEET_API_KEY, ALIASFLEET_DEV_NO_AUTH and talks to aliasfleet.com. 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.

$vet-skills run --secrets ALIASFLEET_API_KEY=aliasfleet.com,ALIASFLEET_DEV_NO_AUTH=aliasfleet.com -- npx -y aliasfleet-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 83/100 (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.
