## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Supply Chain Security**: 0/100
  - 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.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 4 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 66/100
  - 67% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (29% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**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.

## 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.

## MCP tools (7)

### `bulletin_by_id` (~511 tokens)

🚨 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.

Input parameters:

- `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` (required): Single 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…
- `references` (boolean): 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,…

Output parameters:

- `result`

### `search_lucene` (~302 tokens)

🔍 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.

Input parameters:

- `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…
- `query` (string, required): Lucene 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 -…
- `size` (integer): Maximum number of results to return. Default is 20, hard-capped at 100 regardless of caller.
- `skip` (integer): Number of results to skip for pagination. Default is 0.

### `audit_software` (~175 tokens)

🔍 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.

Input parameters:

- `body` (object, required): Request 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…

### `get_supported_os` (~28 tokens)

List supported OS identifiers/versions for Linux package audit. Get available operating systems for vulnerability analysis.

### `audit_linux_packages` (~305 tokens)

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

Input parameters:

- `include_candidates`: Whether to include potential matches in results. If None, uses default behavior (typically false).
- `os` (string, required): Linux distribution identifier (e.g., ubuntu, debian, centos, rhel, fedora). Use get_supported_os() to see available options.
- `package` (array, required): Installed 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…
- `version` (string, required): Distribution version/release (e.g., 22.04, 12, 8, 40). Must match a supported version for the specified OS.

### `query_autocomplete` (~75 tokens)

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

Input parameters:

- `body` (object, required): Request body containing autocomplete parameters. Should include 'query' field with partial search term (e.g., 'openssl', 'CVE-2024-', 'microsoft windows').

### `search_cpe` (~119 tokens)

Find CPE strings by vendor+product (latest schema). Search for Common Platform Enumeration identifiers in the Vulners database.

Input parameters:

- `product` (string, required): Product name to search for (e.g., 'windows_10', 'chrome', 'http_server', 'java'). Case-insensitive.
- `size`: Maximum number of CPE results to return. If None, uses server default.
- `vendor` (string, required): Vendor name to search for (e.g., 'microsoft', 'google', 'apache', 'oracle'). Case-insensitive.
