Before you give it your token

It will ask for
GROWSURF_API_KEYConfiguration, not credentials: GROWSURF_API_BASE_URL, GROWSURF_CAMPAIGN_ID, GROWSURF_UPLOAD_ALLOWED_ORIGINS
Where it talks to
no vendor host named in the codeAlso growsurf.com, githubusercontent.com, grow.surf, vitalpath.example, ledgerly.example, atlasdesk.example, echokit.example — 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 growsurf.com, githubusercontent.com, grow.surf, vitalpath.example, ledgerly.example, atlasdesk.example, echokit.example as well as its own vendor. The guard injects GROWSURF_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.

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 2026-11-09 and scored it 86/100 (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.
