Changes things 3Claude Code: ask
  • audit_linux_packagesLinux package audit (RPM/DEB) for a given distro + version.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    🔍 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.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    🚨 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.
Only reads 4Claude Code: allow
  • get_supported_osList supported OS identifiers/versions for Linux package audit.No findings

    Why it is in this group

    • The name "get_supported_os" says "get": a word for reading.
    Description, as the server wrote it
    List supported OS identifiers/versions for Linux package audit. Get available operating systems for vulnerability analysis.
  • query_autocompleteAutocomplete helper for search inputs (vendors, products, CVEs, etc.).No findings

    Why it is in this group

    • The name "query_autocomplete" says "query": a word for reading.
    Description, as the server wrote it
    Autocomplete helper for search inputs (vendors, products, CVEs, etc.). Get search suggestions from the Vulners database.
  • search_cpeFind CPE strings by vendor+product (latest schema).No findings

    Why it is in this group

    • The name "search_cpe" says "search": a word for reading.
    Description, as the server wrote it
    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.No findings

    Why it is in this group

    • The name "search_lucene" says "search": a word for reading.
    Description, as the server wrote it
    🔍 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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as vulners. Review it before you use it.
