nel-veil MCP

A free, open-source MCP server that enables AI agents to perform passive security scanning on domains. It provides tools to check for email spoofing risks via DMARC/SPF/DKIM, evaluate TLS certificate validity and protocol versions, audit HTTP security headers, detect publicly exposed files, and assess subdomain takeover risks. It also offers compliance readiness checks against global frameworks like GDPR and ISO 27001, requiring no API keys or signup.
