The server completed its last measured handshake. This is an observation, not a guarantee.

Unmeasured means there is not enough evidence to decide. How these checks work
Start using vulnerable.now
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Find known vulnerabilities in what a project or site runs, ranked by what to fix first. Send exact package versions, the raw content of a lockfile (package-lock.json, poetry.lock, go.sum and others), a CycloneDX or SPDX SBOM, a Wappalyzer export, or detected technologies such as nginx 1.18.0. Returns each finding with severity, exploitation, priority and fixed versions.
DiscoveredEvery known vulnerability in one open source package, most urgent first, with the affected ranges and fixed versions published for that package. Give a version to learn which advisories affect it and the lowest upgrade that leaves every affecting range.
DiscoveredList the public exploit code and proofs of concept the sources link to one vulnerability: Metasploit exploit modules, Exploit-DB entries, references NVD or the CNA tagged as exploits (broken links left out), and GitHub PoC repositories (most stars first). Links only; nothing is downloaded or run. The same JSON as GET /api/v1/entries/{id}/pocs. GitHub PoCs and tagged references are unverified third-party code, and stars are popularity, not review.
DiscoveredEvery known vulnerability in one vendor product, such as an operating system, browser, server, CMS or appliance, most urgent first, with the affected versions and fixes. The vendor is optional: with only a product name, a clear match is answered directly and otherwise the candidates are listed. Give a version to learn which entries affect it and the lowest upgrade that clears them.
DiscoveredGet the merged entry for one or more IDs: CVE, GitHub advisory (GHSA), EUVD, or an OSV ID such as PYSEC, GO or RUSTSEC. Returns the description, CVSS, CISA KEV status, EPSS, public exploits, affected packages, fixed versions, priority and source links.
DiscoveredList vulnerabilities newest first (KEV listings by date added when kev is set). Filter by severity, CISA KEV, exploitation, public exploit code, fix availability, ecosystem, vendor, product, text and dates. Use modified_since to pick up changes since a previous run.
DiscoveredSearch the whole catalog by words: product, vendor, package, CVE ID, common vulnerability name, research metadata or description text. Best match first by default. Each result says which fields matched. When nothing matches, the reply suggests a broader query.
DiscoveredWhat to patch first: the vulnerabilities with the highest priority score (exploitation, EPSS, CVSS, automatability) among those with activity in a time window, optionally narrowed to an ecosystem, vendor or product.
