- Is tithonus live?
- Yes — it answered the hub's last check (checked 4h ago). It answered 100% of checks over the last 30 days.
- Is tithonus free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does tithonus have?
- 5 tools: tithonus_lookup, tithonus_check, tithonus_stamp, tithonus_beacon, tithonus_now.
- Is tithonus 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.

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.
tithonus_beacon open 4h ago
Get public randomness from drand (League of Entropy), relayed and signed by tithonus. Nobody, tithonus included, can predict or choose it. Use for fair coin flips, lotteries or tie-breaks other agents can recheck, or put the answer's token in text before stamping it to prove the text was written after that moment. Omit round for the latest.
{ "type": "object", "properties": { "round": { "type": "integer", "description": "Optional. drand quicknet round number (one every 3 seconds)." } } }arguments 9 linestithonus_now open 4h ago
Get a signed statement of the current UTC time from tithonus.org. It includes the latest drand round, so anyone can see it was made after that moment. Use when you need trustworthy current time, or proof of when you asked. Pass a fresh nonce to bind the answer to your request.
{ "type": "object", "properties": { "nonce": { "type": "string", "description": "Optional. Any string; long or unusual ones are signed as their sha256." } } }arguments 9 linestithonus_lookup unknown never probed
Find the earliest receipt for a sha256 hash, if it was ever stamped. Never creates a stamp.
{ "type": "object", "required": [ "sha256" ], "properties": { "sha256": { "type": "string", "description": "64 hex digits." } } }arguments 12 linestithonus_check unknown 4h ago
Check a tithonus receipt link: is it genuine, and when was it stamped? Optionally give the text to confirm it is exactly what was stamped.
{ "type": "object", "required": [ "receipt" ], "properties": { "text": { "type": "string", "description": "Optional. The text you believe was stamped." }, "receipt": { "type": "string", "description": "The receipt link (https://tithonus.org/r/...) or its token." } } }arguments 16 linestithonus_stamp unknown never probed
Notarise something so you can later prove it existed (or that you knew or said it) by now. Give text and the server salts and hashes it (text is not stored), or give a sha256 you computed. Returns a receipt link anyone can check. Stamping the same hash again returns the original receipt.
{ "type": "object", "properties": { "text": { "type": "string", "description": "The claim, prediction or data to notarise. Keep it exact; you need the identical text to prove a match later." }, "sha256": { "type": "string", "description": "Alternative to text: a 64-hex sha256 you computed (salt guessable content first)." } } }arguments 13 lines
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 id7fd9b14447cbc29c.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/7fd9b14447cbc29c/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.
