tithonus missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

tithonus

tithonus_beacon

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.

tithonus_check

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.

tithonus_lookup

Find the earliest receipt for a sha256 hash, if it was ever stamped. Never creates a stamp.

tithonus_now

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.

tithonus_stamp

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.

tithonus — questions

Answers built from our own checks of this server.

What can tithonus do?

It exposes 5 tools, read directly from the server on our last check. Among them: tithonus_beacon, tithonus_check, tithonus_lookup, tithonus_now, tithonus_stamp. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is tithonus working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 197 ms. The bar chart above shows every period we have measured.

How do I connect tithonus?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does tithonus need an API key?

No. tithonus completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is tithonus?

It answers our handshake in 197 ms on average, which is faster than 71% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is tithonus open source?

The code is open source: it is published under the Apache-2.0 licence, written in JavaScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at tithonus.org, which runs on its operator's own terms.
