Detect malicious or vulnerable npm packages: registry search, OSV.dev and GitHub advisory lookups
Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.
Für diesen Server haben wir noch keine Zusammenfassung in einfacher Sprache geschrieben. Unten stehen die Fakten, die wir aus der Registry gelesen haben.

A Claude Code plugin that gives Claude read-only npm package and vulnerability lookups, backed by npmscan.com's free, unauthenticated MCP server.
NPMScan is also officially listed for both ChatGPT and Claude on npmscan.com's MCP page, so users can verify that this plugin points at the same public service.

npmscan, https://npmscan.com/api/mcp) with twenty-three tools — see Tools below. Every tool result includes an npmscanUrl linking back to the full write-up on npmscan.com. No API key or auth required — same public data as the website. The server is stateless and rate-limited to 30 requests/minute per IP. Every vulnerability finding carries isMalware, so a confirmed-malicious package is reported as malware to remove, never as an ordinary bug.batch_query_vulnerabilities → get_package/get_package_version → analyze_transitive_dependencies → the maintainer/provenance/license/remediation/alternative tools into one dependency-audit report, instead of leaving that tool sequencing to Claude each time. Also handles PR-style before/after diffs via diff_dependencies, raw npm audit --json output via enrich_npm_audit, and a bare GitHub repo URL via audit_github_repository. Triggers automatically when you paste a package.json/lockfile/SBOM, give a GitHub repo URL, or ask to check/audit your dependencies, or invoke it directly. See skills/dependency-audit/SKILL.md.dependency-audit). See skills/package-trust-check/SKILL.md.compare_packages/suggest_alternative/search_packages into a structured side-by-side with a deterministic pick. See skills/new-dependency-evaluation/SKILL.md.get_remediation_playbook steps: real incident references, severity, and prevention tips, not improvised advice. See skills/incident-response/SKILL.md.diff_dependencies/simulate_dependency_upgrade — not a conversational report (that's dependency-audit's job). See skills/ci-pr-gate/SKILL.md.NPMScan provides twenty-three tools:
| Tool | Description |
|---|---|
search_packages | Search the npm registry by name or keywords. Each result includes weekly/monthly download counts, dependent-package counts, and rank among npmscan's own top-100k-by-downloads snapshot, so you can tell an established package from an abandoned or squatted one that merely matches the query text — flags possibleTyposquatOf when a low-popularity result's name is one typo away from a top-5,000 package. |
get_package | Latest version, install scripts (preinstall/install/postinstall/prepare), maintainers, license, recent version history, weekly downloads, GitHub stars, TypeScript support, days since last publish, ecosystem-wide download rank, a 3-month download trend, and an isLatestVersionVulnerable/highestSeverity verdict (with fixed versions and isMalware per finding) — plus a rule-based (not model-generated) maintenance/popularity summary and typosquat flag computed from those numbers. |
get_package_version | Metadata for one exact version plus an OSV.dev check scoped to that version — isVulnerable/highestSeverity as a direct safe/not-safe answer, with each finding's severity, summary, fixed version and isMalware. For checking a version pinned in a lockfile. A version npm has removed but OSV still has advisories for (usually one pulled for being malicious) comes back with versionExists: false and those findings, not a bare "not found". |
get_maintainer_profile | Packages an npm username currently maintains via npm's own maintainer: search index, plus precomputed download/dependent totals across all of them. Lists the most-downloaded limit packages (default 50, max 250); totals still cover every package found. A plain info lookup, not a security check — pair it with check_maintainer_blast_radius for the actual compromised-account signal. |
query_vulnerabilities | OSV.dev lookup for known vulnerabilities affecting a package, optionally scoped to a version, with isVulnerable/highestSeverity as a direct verdict and each finding's severity, summary, fixed version and isMalware. For npm it also cross-checks the name/version against the registry: a name or version that isn't on npm still returns its OSV data, with packageExists: false and an existenceCheckNote — so a typo doesn't read as "clean", and a version removed for malware still shows its findings. Accepts packageName as an alias for name, and other ecosystems via ecosystem (e.g. "PyPI"). |
batch_query_vulnerabilities | OSV.dev lookup across a whole dependency inventory at once — pass a flat packages list, or paste raw package.json/lockfile/CycloneDX JSON/SPDX JSON content via content and it parses that for you. Chunks large inventories internally, with severity, summary, CVE aliases, fixed version and isMalware per finding. Also reports names/versions that aren't on npm (unresolvedPackages/nonexistentVersions — never read those as clean), per-package signals (deprecated, install scripts, popularity, typosquat), and for lockfiles a source check that flags a tarball from an unexpected host or one that is a different package than declared (identityMismatch). |
get_latest_advisories | Recently published npm advisories from one of three sources (one per call): type: "reviewed" (default) is GitHub's curated, mostly CVE-backed set, filterable by severity, vulnerability category, affected package name, or an exact GHSA/CVE ID; type: "malware" is GitHub's own malicious-package advisories; type: "osv" is OSV.dev's OpenSSF malicious-packages feed (MAL- ids). Cursor-paginated. These are feeds of recent advisories, not a package's full history — to check whether a package is or was malware, use query_vulnerabilities and its isMalware flags. |
get_cve | NIST NVD lookup for one exact CVE ID (authoritative CVSS score/vector, CWEs, references), or a keyword/severity/CWE/date-range search. Enriched with CISA KEV status (actively exploited in the wild?) and FIRST.org EPSS (30-day exploitation probability). Falls back to the raw MITRE CVE record when NVD has no data yet. Not npm-scoped — NVD covers every ecosystem. |
analyze_install_script | Fetches a package's published tarball and statically scans its preinstall/install/postinstall/prepare lifecycle scripts — and the files they reference, pulled from the tarball itself — against npmscan's red-flags rubric (child_process use, network calls, sensitive-path/env access, obfuscation, untrusted remote binaries, exfil hosts, eval on decoded strings, CI telemetry) plus a typosquat check. Returns a totalScore and riskTier. A prepare-only package scores 0 unless its command does something alarming, since npm never runs a dependency's prepare on install. A heuristic static scan, not proof of malice — it doesn't execute code or check maintainer history. |
analyze_transitive_dependencies | Recursively resolves 1-15 direct/root packages' dependency graphs to a configurable depth (default 2, max 3) and batch-checks every resolved package against OSV.dev — surfaces vulnerabilities buried several levels deep that a flat batch_query_vulnerabilities call would miss, with vulnerablePaths naming which direct dependency pulled in each vulnerable transitive package. A total-node budget caps runaway graphs, reported via truncated/truncationNote rather than silently returning a partial scan as complete. |
check_package_provenance | Checks a version's npm/Sigstore publish provenance against reality: flags a non-GitHub-hosted builder or an attested source repo that doesn't match package.json's own repository field; flags a package missing provenance while its npm-scope/maintainer peers consistently have it (skipped for versions published before npm provenance existed, 2023-04-19); and diffs the published tarball's install scripts/dependencies against the source repository at the attested commit — the pattern of a stolen-npm-token publish that bypasses CI. For a version npm has removed, the error names any OSV advisories for it. Structural only, not a cryptographic re-verification of the Sigstore bundle. |
check_maintainer_changes | Reconstructs a package's maintainer-add/remove history from the npm packument and flags account-takeover patterns — a new maintainer who published shortly after being added, a sudden full maintainer-list replacement, a long-standing maintainer quietly dropped, or a maintainer change not yet tied to any release. Also cross-checks the declared GitHub repository for transfers/archival. |
| check_maintainer_blast_radius | Given an npm username, finds the packages that account currently maintains and flags a tight cluster of packages pub
