Coverage

Startup only; authenticated tool behavior not tested.
Tested
server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
Not tested
the tool list (the server exited before answering) · what the tools do when called with real credentials

What this means for the label: Verified 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
MCP_AUTH_SECRETSCAVIO_API_KEYConfiguration, not credentials: DASHBOARD_URL, ISSUER_URL, PLATFORM_KEYS, SCAVIO_API_BASE_URL, SCAVIO_PLATFORMS, TRANSPORT
Where it talks to
scavio.dev (its own)Also glama.ai, cvs.com, menards.com, sephora.com, specsonline.com, ulta.com, vinted.co.uk — 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
the tool list (the server exited before answering) · 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 glama.ai, cvs.com, menards.com, sephora.com, specsonline.com, ulta.com, vinted.co.uk as well as its own vendor. The guard injects MCP_AUTH_SECRET, SCAVIO_API_KEY only into requests to scavio.dev (and its subdomains) and refuses the rest.

$vet-skills run --secrets MCP_AUTH_SECRET=scavio.dev,SCAVIO_API_KEY=scavio.dev -- npx -y @scavio/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; startup only; authenticated tool behavior not tested) on 2026-11-11 and scored it 88/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
