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
KBC_KUBERNETES_TOKEN_PATHKEBOOLA_MCP_SERVER_OAUTH_LOG_ALL or --storage-token / --show-tokenConfiguration, not credentials: APP_ENV, APP_VERSION, HOSTNAME_SUFFIX, KBC_PKCE_CLIENT_ID, KBC_STORAGE_API_URL, LOG_CONFIG
Where it talks to
keboola.com (its own)Also gofastmcp.com, claude.ai, chatgpt.com, cursor.com, evil.example — 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 gofastmcp.com, claude.ai, chatgpt.com, cursor.com, evil.example as well as its own vendor. The guard injects KBC_KUBERNETES_TOKEN_PATH, KEBOOLA_MCP_SERVER_OAUTH_LOG_ALL only into requests to keboola.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets KBC_KUBERNETES_TOKEN_PATH=keboola.com,KEBOOLA_MCP_SERVER_OAUTH_LOG_ALL=keboola.com -- uvx keboola-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 (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-10 and scored it 78/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Privileged sudo command; URL with embedded credentials; Privileged sudo command. Summary: no network, touches nothing outside the project, writes no memory.
