mcp-warden@r1

CAUTION· install only

Publisher claims: "Local credential broker for AI agents: they call HTTP APIs, SSH, SFTP and databases through allow-listed presets while secrets stay in the OS keychain. Per-preset approval (desktop, terminal or Telegram) and an append-only audit log." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

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
GITHUB_TOKENPROXY_CHILD_TOKEN_URLTOKENConfiguration, not credentials: AUDIT_H1_CONFIRMED, AUDIT_H1_DIR, AUDIT_H2_OUT, AUDIT_H4_OUT, AUDIT_H4_PATH, AUDIT_H5_UPSTREAM, DIALOG_ENV_FAKE, DIALOG_ENV_OUT, MCP_WARDEN_APPROVAL_TRANSPORT, MCP_WARDEN_BACKEND, MCP_WARDEN_CONFIG_DIR, OSENV_OUT
Where it talks to
no vendor host named in the codeAlso attacker.example, evil.localhost, telegram.org, amazonaws.com, gitlab.example, x.example, attacker.com, example.test, example.org, x.dev, 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 attacker.example, evil.localhost, telegram.org, amazonaws.com, gitlab.example, x.example, attacker.com, example.test, example.org, x.dev, evil.example as well as its own vendor. The guard injects GITHUB_TOKEN, PROXY_CHILD_TOKEN_URL, TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- <the server's command>

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

Is mcp-warden@r1 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 2026-11-14 and scored it 62/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Destructive command against a filesystem root or device; Image alt text carrying instructions; Destructive command against a filesystem root or device. Summary: no network, touches nothing outside the project, writes no memory.
