Coverage

Install scripts ran; no agent task scenario for this bundle.
Tested
install scripts, with decoy credentials in place · second launch with the clock 45 days ahead · every file read, file written and host contacted by what ran
Not tested
use of the skill by an agent

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
LASSO_API_KEYConfiguration, not credentials: LASSO_CONVERSATION_ID, LASSO_USER_ID, LOGLEVEL, XETRACK_DB_PATH, XETRACK_FLATTEN_ARGUMENTS, XETRACK_FLATTEN_RESPONSE, XETRACK_LOG_FORMAT, XETRACK_LOG_NETWORK_PARAMS, XETRACK_LOG_SYSTEM_PARAMS, XETRACK_LOGS_PATH, XETRACK_LOGS_STDOUT, XETRACK_WARNINGS
Where it talks to
no vendor host named in the codeAlso lasso.security — 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
use of the skill by an agent

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names lasso.security as well as its own vendor. The guard injects LASSO_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx mseep-mcp-gateway

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; install scripts ran; no agent task scenario for this bundle) on 2026-11-12 and scored it 89/100 (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.
