Cybersecurity MCP Server — Vulnerability & Security Intelligence for AI Agents

An MCP (Model Context Protocol) server that gives AI agents — Claude Desktop, Cursor, Windsurf, ChatGPT, and any MCP-compatible client — a single connection to a full vulnerability and security-intelligence toolkit for DevSecOps, threat intel, and security operations.

Instead of wiring up eight separate actors, point your agent at one MCP endpoint and it gains live tools for CVEs, actively-exploited vulnerabilities, dependency advisories, DNS, TLS/SSL, domain security posture, and Chrome-extension risk analysis.

This is an MCP server, not a scraper. Running it directly only prints connection instructions. Connect from an MCP client to use the tools.

Streamable HTTP endpoint:

Claude Desktop / Cursor / Windsurf (mcp config):

{
  "mcpServers": {
    "cybersecurity": {
      "url": "https://nexgendata--cybersecurity-mcp-server.apify.actor/mcp",
      "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" }
    }

🛡️ Tools

Tool	What it does
search_cves	Search recent CVE records by keyword (vendor/product/tech) — IDs, descriptions, CVSS severity, dates
cisa_kev	Query CISA's Known Exploited Vulnerabilities catalog + EPSS exploit-probability scores and due dates
dependency_advisories	Known security advisories (CVE/GHSA) for npm / PyPI / other package dependencies
dns_lookup	Bulk DNS records — A/AAAA, MX, NS, TXT (SPF/DKIM/DMARC), CNAME, SOA
dns_propagation	Check DNS propagation across global resolvers (cutover / migration verification)
ssl_check	TLS/SSL certificate inspection — issuer, validity, expiry, chain, protocol
domain_security_posture	Composite domain security score — email auth, DNSSEC, TLS, security headers
extension_security	Chrome-extension risk analysis — permissions, host access, risk scoring (CRXcavator-style)

🎯 Use Cases

• Vulnerability triage — an agent pulls new CVEs for your stack, cross-checks CISA KEV for active exploitation, and flags what to patch first.
• Dependency / supply-chain risk — feed a package.json or requirements.txt and get advisories per dependency.
• Attack-surface & domain hygiene — DNS records, SSL expiry, and a security-posture score for any domain portfolio.
• Browser-extension governance — score the Chrome extensions your org allows for permission risk.
• Continuous monitoring — agents call these tools on a schedule and alert on changes.

🧪 Example agent prompts

• "Are there any critical CVEs for Fortinet in the last week? Check CISA KEV too."
• "Audit lodash and django for known advisories."
• "What's the SSL expiry and security posture for github.com?"

⚙️ How it works

Each MCP tool proxies to a dedicated, production-tested NexGenData security actor via the Apify API and returns the resulting dataset items as structured content. No re-implementation of scraping — the server orchestrates eight existing actors behind one MCP surface.
