ExposureGuard is a domain security scanning platform that grades any domain A through F based on 8 automated checks: SPF, DMARC, SSL/TLS, HTTPS redirect, security headers, DNSSEC, open ports, and MX records. This MCP server exposes 4 tools for AI agents to scan domains, retrieve cached grades, get copy-paste remediation fixes, and discover third-party supply chain dependencies. Built for security teams, DevSecOps pipelines, and AI agents that need to vet domains before interacting with them.
