Before you give it your token

It will ask for
MICROLINK_API_KEYConfiguration, not credentials: MICROLINK_CONNECT_TIMEOUT_MS, MICROLINK_DASHBOARD_URL
Where it talks to
microlink.io (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 MICROLINK_API_KEY and talks to microlink.io. 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 MICROLINK_API_KEY=microlink.io -- npx -y @microlink/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 (3 scenarios) on 2026-11-09 and scored it 90/100 (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.
