InboxGuards Email Check: check an email address before sending. Use validate_email (free, offline syntax) and pricing (free) first, then check_email_address for MX, disposable, role-account and free-provider flags with an ok/risky/undeliverable verdict. No SMTP probe is made and nothing is stored. Payment is x402 USDC on Base in _meta['x402/payment']; invalid or failed calls are not charged.

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 9 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.
pricing open 1h ago
Free. Return the price of check_email_address (and of the HTTP-only email test report), the payment network (Base) and the receiving address. No input, no network request, no payment.

Check one email address before you send to it: syntax, whether the domain accepts mail (MX, null MX or implicit A record), a disposable-domain flag (public CC0 list of about 9,900 domains), a role-account flag (info@, support@, noreply@...) and a free-provider flag. Returns a verdict of ok, risky or undeliverable with plain reasons. Use validate_email first if you only need syntax. No SMTP probe is made and no mail is sent, so it cannot confirm the mailbox exists. The address is not stored or logged. Read-only; one live DNS lookup via Cloudflare DoH. Costs $0.005 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or a DNS failure returns an error and is not charged.

Free. Check the syntax of an email address offline and get the normalized address and domain, before paying for check_email_address. No DNS lookup, no network request, no payment.

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 ideedd18891680b733.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/eedd18891680b733/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.
