Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution 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.

Before you give it your token

It will ask for
APIFY_TOKENConfiguration, not credentials: APIFY_API_BASE_URL, APIFY_API_PUBLIC_BASE_URL, APIFY_IS_AT_HOME, SKYFIRE_PAY_ID_KEY, SKYFIRE_SELLER_SERVICE_ID, TELEMETRY_ENABLED, TELEMETRY_ENV, UI_MODE
Where it talks to
apify.com (its own)Also crawlee.dev, nodejs.org — 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
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names crawlee.dev, nodejs.org as well as its own vendor. The guard injects APIFY_TOKEN only into requests to apify.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets APIFY_TOKEN=apify.com -- npx -y @apify/actors-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 (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-13 and scored it 73/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Collapsed <details> block carrying instructions; Collapsed <details> block carrying instructions; Collapsed <details> block carrying instructions. Summary: no network, touches nothing outside the project, writes no memory.
