About NIST NVD MCP Server
Connect to the National Vulnerability Database (NVD) API through your AI agent and explore the world's most comprehensive archive of cybersecurity vulnerabilities and product data using natural conversation.
LangChain's ecosystem of 500+ components combines seamlessly with NIST NVD through native MCP adapters. Connect 10 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- CVE Discovery — Search for Common Vulnerabilities and Exposures (CVEs) by ID, keyword, or specific weakness (CWE).
- Product Security — Find all vulnerabilities associated with a specific product or version using its Common Platform Enumeration (CPE) string.
- Severity Analysis — Filter vulnerabilities based on their CVSS V3 severity level (Low to Critical) to prioritize risks.
- Temporal Tracking — Search for CVEs published or modified within specific date ranges to monitor recent threats.
- Product Dictionary — Query the official CPE dictionary by keyword or UUID to identify software and hardware products.
- Change History — Retrieve a detailed log of updates and modifications made to the vulnerability database.
The NIST NVD MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
