Documentation Overview

The VulnCheck MCP Server

The VulnCheck MCP Server connects AI assistants to VulnCheck vulnerability intelligence. Ask your AI tools about CVEs, exploits, advisories, and vulnerable packages — directly in your editor or terminal, using natural language.

Use Cases

CVE research: Look up vulnerability details, severity, exploitability, and affected versions while reviewing code or triaging issues
Dependency analysis: Check packages by CPE or PURL to identify known vulnerabilities before shipping
Exploit intelligence: Determine whether a CVE has known exploit code, active exploitation, or C2 indicators
Advisory lookup: Search vendor and ecosystem advisories by package, product, or keyword
Index queries: Query VulnCheck's breach, botnet, and threat intelligence indices for real-time context

A guidance signal from public completeness & health data — not a user rating. New listings start lower and rise as they add docs, get verified, and grow adoption. Signals we can't observe for a listing are skipped, not counted against it.
