MCP Server Overview

The datanexusmcp/mcp-server MCP server exposes DataNexus lookups for security, package, domain, nonprofit, compliance, legal, and government-contract research. It connects through the hosted MCP endpoint or a local npx process and returns data from public sources such as NVD, OSV.dev, CISA KEV, IRS, NPPES, RDAP, and EPO OPS. Reach for it when an agent needs structured public-data checks rather than access to private repositories or application systems. Anonymous use is available without an API key, with an optional free key for a higher monthly call limit.

Primary Use Cases for MCP Server:
  • Audit an SBOM for known package vulnerabilities
  • Triage a CVE using CVSS, KEV, and EPSS data
  • Check package licences before commercial distribution
  • Investigate domain registration, DNS, and certificate history
