Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 652 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name vulnerable-now.

  • Pass
    Lists tools

    tools/list returned 8 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 652 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 652 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    53 of 64 parameters have a description (83%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-11T01:53:12.686216Z, within 180 days.

  • Not measured
    Open-source licence

Capabilities

Tools 8

check_stack

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.

Discovered
get_package

Every 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.

Discovered
get_poc

List 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.

Discovered
get_product

Every 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.

Discovered
get_vulnerability

Get 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.

Discovered
list_feed

List 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.

Discovered
search

Search 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.

Discovered
top_priority

What 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.
