Registry code: 59b31e7094d6b76a
Checks a domain's email authentication: SPF with a recursive count of the 10-DNS-lookup limit and void lookups, DMARC tags and report authorization, DKIM keys and key size at common or given selectors, MX, MTA-STS, TLS-RPT, BIMI, a Gmail/Yahoo/Outlook bulk-sender readiness summary, and domain expiry via RDAP. GET /v1/email-auth?domain=example.com for the full report (SPF+DMARC+DKIM+MX+MTA-STS+TLS-RPT+BIMI+bulk-sender readiness). GET /v1/spf for the SPF lookup tree only, GET /v1/dmarc for DMARC only, GET /v1/domain-expiry for RDAP registration/expiry. All take a bare domain; deterministic…

- Is dev.workers.quietworklabs.email-auth-check/email-auth-check live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is dev.workers.quietworklabs.email-auth-check/email-auth-check free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does dev.workers.quietworklabs.email-auth-check/email-auth-check have?
- 4 tools: dmarc_check, domain_expiry, email_auth_report, spf_lookup_count.
- Is dev.workers.quietworklabs.email-auth-check/email-auth-check 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, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 4 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

counted from three payers (thin, concentrated, shared-payto)
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.
dmarc_check unknown 2h ago
Finds and validates a domain's DMARC record (falls back to the organizational domain): policy, subdomain policy, pct, alignment modes, rua/ruf, and whether external report domains authorized reports (RFC 7489 7.1). Deterministic, no AI. Price: $0.001 USDC per call via x402 (Base); the first 5 calls per day per client are free.
{ "type": "object", "required": [ "domain" ], "properties": { "domain": { "type": "string", "examples": [ "github.com" ], "description": "Domain to check" } } }arguments 15 linesdomain_expiry unknown 2h ago
Registration data for a domain from the registry's RDAP server (IANA bootstrap): registrar, created/updated/expiry dates, days until expiry with ok/expiring_soon/expired status, EPP status codes, nameservers and DNSSEC. Works for gTLDs and ccTLDs that publish RDAP. Deterministic, no AI. Price: $0.002 USDC per call via x402 (Base); the first 5 calls per day per client are free.
{ "type": "object", "required": [ "domain" ], "properties": { "domain": { "type": "string", "examples": [ "example.com" ], "description": "Domain name" } } }arguments 15 linesemail_auth_report unknown never probed
Full email-auth report for a domain: SPF (recursive 10-lookup count, void lookups, +all/?all, terms after all), DMARC (policy, pct, alignment, rua authorization), DKIM (keys and RSA key bits at common selectors or your own via selectors=), MX/null MX, MTA-STS policy, TLS-RPT, BIMI, and a Gmail/Yahoo/Outlook bulk-sender readiness verdict. Deterministic DNS-over-HTTPS, no AI. Price: $0.003 USDC per call via x402 (Base); the first 5 calls per day per client are free.
{ "type": "object", "required": [ "domain" ], "properties": { "domain": { "type": "string", "examples": [ "github.com" ], "description": "Domain (or email address) to check" }, "selectors": { "type": "string", "examples": [ "google,selector1" ], "description": "Optional comma list of DKIM selectors to probe (max 10)" } } }arguments 22 linesspf_lookup_count unknown 2h ago
Expands a domain's SPF record recursively (include/redirect) like a receiver does and counts DNS-querying terms against the RFC 7208 limit of 10 and void lookups against the limit of 2. Returns per-term lookup costs, problems (permerror causes) and warnings. Deterministic, no AI. Price: $0.001 USDC per call via x402 (Base); the first 5 calls per day per client are free.

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 id59b31e7094d6b76a.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/59b31e7094d6b76a/claim.
Over MCP: the claim_endpoint tool.

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.
