Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security0
  • No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
  • Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
  • Install-script risk not yet assessed.Unverified
  • Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
Provenance & Transparency32
Schema Quality & AI Usability66
  • 67% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Partial
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 1564 tokens (~156/item across 10 items; 7 tools + 3 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
  • Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (29% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools · 7 exposed · ~1,515 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
audit_linux_packages ~305

Linux package audit (RPM/DEB) for a given distro + version. Analyze Linux package vulnerabilities against the Vulners database.

NameTypeReqDescription
include_candidates––Whether to include potential matches in results. If None, uses default behavior (typically false).
osstringyesLinux distribution identifier (e.g., ubuntu, debian, centos, rhel, fedora). Use get_supported_os() to see available options.
packagearrayyesInstalled packages, each formatted EXACTLY as the target OS's own package manager lists them -- i.e. one line of the output produced by the command get_supported_os() returns for this OS. DEB-based d…
versionstringyesDistribution version/release (e.g., 22.04, 12, 8, 40). Must match a supported version for the specified OS.

audit_software ~175

🔍 VERSION-SPECIFIC SOFTWARE AUDIT 🔍 Audit specific software versions for known vulnerabilities. Use this when you have exact software version information (e.g., Chrome 138.0.7204.184). NEVER use search_lucene for version-specific software audits.

NameTypeReqDescription
bodyobjectyesRequest body containing software list and audit parameters. Should include 'software' array with structured CPE objects (NOT CPE strings) and optional 'match' parameter ('partial' or 'full'). Each CP…

bulletin_by_id ~511

🚨 PRIMARY TOOL FOR KNOWN IDs 🚨 Fetch a bulletin by CVE or Vulners ID. Returns a COMPACT triage-card summary by default -- id, title, CVSS3, EPSS, CVE list, and a compact exploitation/AI signal -- NOT the full record. Pass fields=[...] to widen (e.g. add 'description', 'cvss', 'cvss2', 'affectedSoftware') or references=True for the linked-bulletin graph; requesting everything can be very large. Supports single ID or list of IDs. When list is provided, references are automatically set to False. NEVER use search_lucene for known IDs.

NameTypeReqDescription
fields––Override the default COMPACT field projection to widen the response. Pass ['*'] to request every field Vulners has for the bulletin (can be very large for popular CVEs). Useful individual fields to a…
id–yesSingle CVE ID, Vulners ID, or bulletin ID to fetch, or a list of IDs. Supports CVE identifiers (CVE-2024-21762), vendor-specific IDs (RHSA-2024:1234), or Vulners internal IDs. When a list is provided…
referencesboolean–Include the full reference graph (linked advisories, patches, related bulletins) for a SINGLE-ID lookup. Defaults to False: the compact default projection already covers the essentials (CVSS3, EPSS,…

query_autocomplete ~75

Autocomplete helper for search inputs (vendors, products, CVEs, etc.). Get search suggestions from the Vulners database.

size––Maximum number of CPE results to return. If None, uses server default.
vendorstringyesVendor name to search for (e.g., 'microsoft', 'google', 'apache', 'oracle'). Case-insensitive.

No output schema declared.

No examples provided.

search_lucene ~302

🔍 DISCOVERY TOOL FOR UNKNOWN VULNERABILITIES 🔍 Full-text search in Vulners Knowledge Base using Lucene syntax. Use ONLY when you don't have specific IDs or version information. NEVER use for known CVE/bulletin IDs - use bulletin_by_id instead. NEVER use for specific software versions (e.g., 'Chrome 138.0.7204.184') - use audit_software instead. 🚨 CRITICAL: For vendor/product searches, ALWAYS use cnaAffected.vendor and cnaAffected.product fields - the affectedSoftware field does NOT exist.

NameTypeReqDescription
fields––Override the default curated per-hit field projection. Pass ['*'] for every field per hit (large responses). If omitted, a curated default is used: id, title, type, cvss, cvss3, epss, published, href…
querystringyesLucene query string for searching vulnerabilities. Supports Boolean operators (AND, OR, NOT), field-specific queries, range searches, and wildcard matching. NEVER use for specific software versions -…
sizeinteger–Maximum number of results to return. Default is 20, hard-capped at 100 regardless of caller.

Install

How do I install the io.github.vulnersCom/vulners-mcp server?

io.github.vulnersCom/vulners-mcp runs locally as a container image, launched with docker run --rm -i -e VULNERS_API_KEY ghcr.io/vulnerscom/vulners-mcp:1.15.0. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

oci · ghcr.io/vulnerscom/vulners-mcp

# add to Claude Code
claude mcp add vulnerscom-vulners-mcp -- docker run --rm -i -e VULNERS_API_KEY ghcr.io/vulnerscom/vulners-mcp:1.15.0

This image reads VULNERS_API_KEY. Set it in your client's env block for this server; docker run -e passes it through to the container.
