HeaderGuard

Rank #161,216

smithery/mike-tusa/headerguard

HeaderGuard is a free security-headers scanner for any public website: it checks HTTPS and HSTS, Content-Security-Policy, framing, MIME sniffing, Referrer-Policy, Permissions-Policy, cross-origin isolation and cookie flags. You get a 0–100 score, an A+ to F grade, per-header findings and copy-paste fixes. No key needed (about 30 scans per minute per IP); an optional HeaderGuard Pro license key ($9/mo) raises that to about 120 per minute. Quick start: connect directly to https://headerguard.mike-tusa.workers.dev/mcp (Streamable HTTP, no Smithery account needed).
