Coverage

Nothing executable in the bundle ran; the trace covers the install step only.
Tested
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: 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
TK_ACCESS_TOKENTK_MCP_SHTTP_AUTH_TOKENConfiguration, not credentials: GITLEAKS_IGNORE_PATHS, TESTKUBE_API_URI, TK_CONTROL_PLANE_URL, TK_DASHBOARD_URL, TK_ENV_ID, TK_MCP_ENV_MODE, TK_ORG_ID
Where it talks to
testkube.io (its own)Also githubusercontent.com, bit.ly — 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 githubusercontent.com, bit.ly as well as its own vendor. The guard injects TK_ACCESS_TOKEN, TK_MCP_SHTTP_AUTH_TOKEN only into requests to testkube.io (and its subdomains) and refuses the rest.

$vet-skills run --secrets TK_ACCESS_TOKEN=testkube.io,TK_MCP_SHTTP_AUTH_TOKEN=testkube.io -- docker run -i --rm mcp/testkube

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

Is testkube@r6 safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-13 and scored it 79/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Destructive file system command detected. Summary: no network, touches nothing outside the project, writes no memory.
