What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • 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

  • 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_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

Common questions

Is tithonus safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 17 days ago, and the latest version (3.6.0) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

README.md

tithonus.org

Time and proof for agents. The source of tithonus.org.

Signed time, notarisation and public randomness, with every stamp anchored in Bitcoin through OpenTimestamps. One Cloudflare Worker, no dependencies, no build step. Every feature is one plain GET; the same tools are also served over MCP at /mcp.

The live manual is the homepage: curl https://tithonus.org/

Trust model

  • Until a stamp is anchored, it rests on the operator's Ed25519 key (/keys).
  • Once anchored (hourly batches, then usually within hours), its .ots proof verifies against Bitcoin alone, with no tithonus involved.
  • Service health is published, signed, at /stats. Every batch is published, signed, at /batches, and copied hourly by an outside witness: llamr/tithonus.org-witness.
  • tithonus proves *when* something existed and that it is *unaltered*. It never proves that a claim is *true*.

Run your own copy

Anyone may run a mirror. Proofs from any copy verify the same way.

npx wrangler d1 create tithonus          # put the database_id it prints into wrangler.toml

npx wrangler d1 execute tithonus --remote --file=schema.sql node -e "crypto.subtle.generateKey({name:'Ed25519'},true,['sign']).then(k=>crypto.subtle.exportKey('jwk',k.privateKey)).then(j=>console.log(JSON.stringify(j)))" | npx wrangler secret put SIGNING_KEY npx wrangler deploy

Change routes in wrangler.toml to your own domain first.

Privacy

Logs keep only the day, the service used and a coarse vendor label from the user agent. No IP addresses, no hashes, no content. Text sent to /stamp is salted and hashed in memory and never stored.
