io.sepiace由 sepiace.io 发布官方发布者v0.2.0更新于 Oct 24, 2026
Long-term memory for AI agents. Pass one sentence, and it remembers, recalls, or forgets.
概览
面向 AI 智能体的远程长期记忆服务：助手只需传入一句自然语言，即可跨会话记住、回忆、搜索或遗忘事实。
- 可以做什么
- 用一句自然语言记住用户的持久事实，例如偏好或决定，并按账户存储在服务器上。用自然语言提问来回忆或搜索已存记忆，返回内容仅为记忆文本。按请求遗忘某条记忆，并用新句子替换过时的事实。可选地把 Claude Code 和 Codex 中已有的本地记忆迁移到该服务，并更新各客户端中的插件与技能。
- 适用场景
- 当你希望助手在会话之间保留偏好、决定等持久事实、无需反复说明，并且可以接受把这些记忆存放在与账户绑定的托管服务上时适用。
- 运行要求
- 需要将 hi.sepiace.io 作为远程 MCP 服务器添加，使用 Streamable HTTP，并通过浏览器 OAuth 登录。可选的安装助手通过 npm 运行，可配置 Claude Code、Codex、Cursor、VS Code 和 OpenCode。未声明环境变量或请求头。
安装
在 SourceWeft 中
- 打开 控制台中的 sepiace，将其添加到工作区。
- 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
- 为需要使用其工具的对话启用该服务。
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。
交给智能体安装
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/io.sepiace%2Fsepiace/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。其他 MCP 客户端
把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

sepiace
Long-term memory for AI agents. Your agent passes one natural-language sentence, and sepiace remembers, recalls, or forgets.
[Star sepiace on GitHub]
If sepiace helps you, a star keeps us going.
[!IMPORTANT] sepiace is in beta. Memories are stored on the sepiace server at
hi.sepiace.io, separately for each account. Do not ask your agent to remember passwords, API keys, or other secrets.
Quick start
It finds Claude Code, Codex, Cursor, VS Code, and OpenCode on your machine, connects the ones you choose, and walks you through signing in. Then start a new session and ask your agent:
- "Remember that I prefer pnpm over npm."
- "What did we decide about the release schedule?"
- "Forget my old home address."
To bring over what your agent already remembers, run /sepiace:migrate in Claude Code, or ask other clients to use the sepiace-migrate skill. It shows you what it found and sends nothing until you agree.
Install by hand
Claude Code:
Codex:
Other MCP clients: add https://hi.sepiace.io/api/v1/mcp as a remote MCP server (Streamable HTTP). The client signs in through OAuth in the browser.
Technology
One sentence in, memory text out
Your agent writes what it wants in plain words. A judgment network on the server decides whether to save, recall, search, or forget, and combines them when needed. The response contains only memory text, with no IDs, dates, or scores, so the agent spends no tokens building structured arguments.
Memories are your own words
Each memory is cut from the sentences in the request. No LLM writes or rewrites it, and when something becomes outdated, only that sentence is replaced. A memory stays in the language you wrote it in.
Memories fade unless they are used
Each memory's score follows the FSRS forgetting curve and is computed when it is read. Memories that go unused fade, and once a memory's recall probability drops below 50%, it no longer appears in search. Each recall makes it stick.
Your memories stay yours, and you can see every request
Memories are kept separately for each account, and every database query and vector search is scoped to the signed-in user. The console at hi.sepiace.io lists every request with the memories it changed, and a client you disconnect there stops working right away.
Measured with KiokuBench
KiokuBench checks what a memory system actually stored: whether it kept the facts, replaced outdated ones, forgot what it was asked to forget, and stayed tidy. The KiokuBench Index combines these four pillars into one number from 0 to 100.
KiokuBench v0.1, 10 personas in English and Japanese, raw conversation passed in as is. sepiace was measured on October 14, 2026, and the others between September 27 and 30, 2026. KiokuBench was designed and run by the team that builds sepiace. The method, the eight metrics, the conditions for each system, and the limitations are on sepiace.io.
