Signed time, Bitcoin-anchored notarisation and drand randomness for agents. No account.
遠端 MCP 伺服器，為助理提供簽章 UTC 時間、比特幣錨定的存證回執與 drand 公開隨機數。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/org.tithonus%2Fmcp/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

}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/
/keys)..ots proof verifies against Bitcoin alone, with no tithonus involved./stats. Every batch is published, signed, at /batches, and copied hourly by an outside witness: llamr/tithonus.org-witness.Anyone may run a mirror. Proofs from any copy verify the same way.
Change routes in wrangler.toml to your own domain first.
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.

Signed current time
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.
nonceNotarise
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.
textsha256Check receipt
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.
textreceipt必填Look up stamp
Find the earliest receipt for a sha256 hash, if it was ever stamped. Never creates a stamp.
sha256必填Randomness 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.
