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
Needs
UTEAMUP_API_KEY, UTEAMUP_SECRET — give it to the server where it runs, through vet-skills run --secrets, so the value never enters the server's environment. Never paste a credential into a chat, a ticket or a report.

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
UTEAMUP_API_KEYUTEAMUP_SECRETUTEAMUP_TOKEN_CACHE_DIRUTEAMUP_TOKEN_REFRESH_MARGIN or --test-authConfiguration, not credentials: UTEAMUP_API_BASE_URL, UTEAMUP_DEBUG, UTEAMUP_INSECURE_TLS, UTEAMUP_LOG_FORMAT, UTEAMUP_LOG_LEVEL, UTEAMUP_MAX_REQUEST_BYTES, UTEAMUP_MAX_RESPONSE_BYTES, UTEAMUP_MAX_RETRIES, UTEAMUP_MCP_PATH, UTEAMUP_REQUEST_TIMEOUT
Where it talks to
uteamup.com (its own)
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. It asks for UTEAMUP_API_KEY, UTEAMUP_SECRET, UTEAMUP_TOKEN_CACHE_DIR, UTEAMUP_TOKEN_REFRESH_MARGIN and talks to uteamup.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. What the tools do with a real credential was not observed.

$vet-skills run --secrets UTEAMUP_API_KEY=uteamup.com,UTEAMUP_SECRET=uteamup.com,UTEAMUP_TOKEN_CACHE_DIR=uteamup.com,UTEAMUP_TOKEN_REFRESH_MARGIN=uteamup.com -- npx -y @uteamup/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 2026-11-13 and scored it 92/100 (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 (it asks for UTEAMUP_API_KEY, UTEAMUP_SECRET); the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
