keyhalve-verify
Registry code: cbed1f84a35397ae
Free, public verification of KeyHalve-sealed documents (from any platform on the rail: ValidPay, CheckBooks, …). Use keyhalve_verify with a verify URL or QR text. This server never receives decryption keys — sealed contents remain readable only in the holder's browser.

- Is keyhalve-verify live?
- Yes — it answered the hub's last check (checked 31m ago). It answered 100% of checks over the last 30 days.
- Is keyhalve-verify free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does keyhalve-verify have?
- 3 tools: keyhalve_verify, keyhalve_status, keyhalve_explain.
- Is keyhalve-verify 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.

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.
keyhalve_explain reads open 18h ago
Plain-language explanation of what a KeyHalve verification verdict means and why it can be trusted (blind rail, three-share custody, commitments, revocation). Optionally focused on one topic.
{ "type": "object", "properties": { "topic": { "enum": [ "verdict", "blindness", "rail", "revocation", "integrity", "issuer_trust", "limits" ], "type": "string", "description": "Optional single topic; omit for the overview." } } }arguments 18 lineskeyhalve_verify reads unknown 18h ago
Verify a KeyHalve-sealed document. Accepts a verify URL, the raw text of a KeyHalve QR code, or a document id (vp_…, kh_…, cb_…). Returns the cryptographic verdict: whether the seal exists, its live status (active/revoked/expired), ciphertext integrity against the issuance commitment, the KeyHalve rail's independent attestation, the validity window, and the issuer's trust context. This tool NEVER decrypts sealed contents — any decryption key in the URL fragment is discarded unread; contents are only readable by opening the verify URL in a browser.

Live status of a KeyHalve-sealed document by id: active, revoked (with reason/time), or outside its validity window. Lighter than keyhalve_verify — status only, no integrity or rail checks. Use for "is this still good right now?"

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 idcbed1f84a35397ae.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/cbed1f84a35397ae/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.
