Is patchbell@0.1.0 safe to install?

patchbell@0.1.0

VERIFIED· install only

Publisher claims: "An MCP server that lets AI agents manage a local watchlist of the software and exact versions you run, then check them against vulnerability and exploitation data. It enables adding, updating and listing watched items, pulling current alerts or recent findings, and asking whether a given CVE affects anything on the list." 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: 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: GITHUB_TOKENNVD_API_KEYConfiguration, not credentials: GITHUB_API_URL, GITHUB_REPOSITORY, PATCHBELL_CVE_URL, PATCHBELL_EOL_URL, PATCHBELL_EPSS_URL, PATCHBELL_HOME, PATCHBELL_KEV_URL, PATCHBELL_NPM_URL, PATCHBELL_NVD_DELAY_MS, PATCHBELL_NVD_URL, PATCHBELL_OSV_URL, PATCHBELL_PYPI_URL, PATCHBELL_RETRY_MS, PATCHBELL_TELEGRAM_URL
Where it talks to: no vendor host named in the codeAlso endoflife.date, nist.gov, osv.dev, ntfy.sh, cisa.gov, first.org, mitre.org, telegram.org, buymeacoffee.com, apple.com — 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 endoflife.date, nist.gov, osv.dev, ntfy.sh, cisa.gov, first.org, mitre.org, telegram.org, buymeacoffee.com, apple.com as well as its own vendor. The guard injects GITHUB_TOKEN, NVD_API_KEY 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.

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 85/100 (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.
