## Trust

- hygiene: 95
- liveness: 100
- freshness: 100
- provenance: 75
- drivers: +repository +namespace-matches-repo -thin-description +reachable +uptime-100% +updated-6d-ago -unpinned-packages(1)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 73/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_supported_os (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); audit_software (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bulletin_by_id (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 2,312 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 6 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know vulners-mcp@1.15.0

- tools: 7, about 2,312 tokens to load them all
- tool set hash: ad59347f10566bdcd1fb8fb11e4110cd
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.vulnersCom/vulners-mcp.svg)](https://protogrid.dev/servers/io.github.vulnersCom/vulners-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `audit_linux_packages`: Linux package audit (RPM/DEB) for a given distro + version. Analyze Linux package vulnerabilities against the Vulners database.
- `audit_software`: 🔍 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.
- `bulletin_by_id`: 🚨 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.
- `get_supported_os`: List supported OS identifiers/versions for Linux package audit. Get available operating systems for vulnerability analysis.
- `query_autocomplete`: Autocomplete helper for search inputs (vendors, products, CVEs, etc.). Get search suggestions from the Vulners database.
- `search_cpe`: Find CPE strings by vendor+product (latest schema). Search for Common Platform Enumeration identifiers in the Vulners database.
- `search_lucene`: 🔍 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.
