api record

Stamp: Stamp checks a domain's email authentication from live DNS: SPF with the 10-lookup limit, DMARC, DKIM keys and MX. It says whether you meet the Gmail, Yahoo and Outlook sender rules and gives you the exact DNS records to fix what is wrong. No account. Use it when the user asks why their email goes to spam, whether SPF, DKIM, DMARC or MX are set up right for a domain, whether they meet the Gmail, Yahoo and Outlook sender rules, or before they publish an SPF, DMARC or DKIM record. Tools: stamp_check_email_domain (Check a domain's email authentication (SPF, DKIM, DMARC, MX) from live…

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.

  • stamp_check_email_domain unknown never probed

    Use when the user asks why their email goes to spam, whether their domain is set up to send email, or before they launch a newsletter, cold outreach, transactional email or a new sending service, e.g. "why are my emails going to spam?", "is my SPF/DKIM/DMARC right?", "do I meet Gmail and Yahoo's sender requirements?" or "I added SendGrid, did I break SPF?".

  • stamp_check_dns_record unknown never probed

    Use when you or the user are about to publish or edit an SPF, DMARC or DKIM TXT record, for example after writing a new SPF record that adds a sending service, or when the user pastes a record and asks "is this right?". Detects the record type. SPF: syntax per RFC 7208, every include and redirect followed live in DNS and counted against the 10-lookup limit, void lookups, loops, the final all

_ try it over a2a through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 524b2eff4e27f654.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/524b2eff4e27f654/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.

_ how we knowoff the mcp door
card completeness
60%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
