Registry code: e188386576e6ffd9
HeaderGuard scans the HTTP security headers of a public website (HTTPS redirect, HSTS, Content-Security-Policy, X-Frame-Options / frame-ancestors, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/CORP/COEP, cookie flags, version leaks) and returns a 0–100 score, an A+–F grade, per-header findings and copy-paste fixes. Call scan_headers with a URL or a bare domain such as example.com. Only public http(s) hosts on ports 80, 443, 8080 and 8443 can be scanned; private, loopback and internal addresses are refused. If the site blocks or challenges the scanner, no grade is given…

- Is headerguard live?
- Yes — it answered the hub's last check (checked 51m ago). It answered 100% of checks over the last 30 days.
- Is headerguard free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does headerguard have?
- 1 tool: scan_headers.
- Is headerguard safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
scan_headers unknown 51m ago
Scan the HTTP security headers of a public website. Returns a 0–100 score and A+–F grade (HTTPS 10, HSTS 15, CSP 25, framing 10, X-Content-Type-Options 10, Referrer-Policy 10, Permissions-Policy 5, COOP 5, CORP 5, cookies 5, minus up to 5 for version-leak headers; without HTTPS the score is capped at 39), each header's status and notes, recommended fix headers, and a link to the full report with copy-paste snippets for nginx, Apache, Cloudflare, Netlify, Vercel and Express. Read-only: it sends ordinary GET requests to the site (following up to 10 redirects, each safety-checked) and never reads page bodies. Same engine and scoring as the HeaderGuard JSON API (GET /api/scan).

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's ide188386576e6ffd9.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/e188386576e6ffd9/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
