Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/org.tithonus%2Fmcp/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}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.
