package-version-check-mcp@1.2.40

VERIFIED· not started

Publisher claims: "A MCP server that returns the current, up-to-date version of packages you use as dependencies in a variety of ecosystems, such as Python, NPM, Go, or GitHub Actions" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

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_PATConfiguration, not credentials: PACKAGE_VERSION_CACHE_ENABLED, PACKAGE_VERSION_CACHE_MAX_SIZE_MB, PACKAGE_VERSION_CACHE_TTL_SECONDS
Where it talks to
no vendor host named in the codeAlso githubusercontent.com, pub.dev, golang.org, maven.org, google.com, nuget.org, packagist.org, rubygems.org, crates.io, bitnami.com, gradle.org, k8s.io, windows.net — 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
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names githubusercontent.com, pub.dev, golang.org, maven.org, google.com, nuget.org, packagist.org, rubygems.org, crates.io, bitnami.com, gradle.org, k8s.io, windows.net as well as its own vendor. The guard injects GITHUB_PAT only into requests to the host you bind (and its subdomains) and refuses the rest.

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; not started: dependency install failed; the server itself was not observed) on 2026-11-14 and scored it 87/100 (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.
