Overview

Description from the maker (original English)

Local-first agent persona runtime (MCP): cross-session personality that survives compaction.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "stemem": {
      "command": "npx",
      "args": [
        "-y",
        "stemem"
      ]
    }
  }
}

Run this in your terminal

claude mcp add stemem -- npx -y stemem

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "stemem": {
      "command": "npx",
      "args": [
        "-y",
        "stemem"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "stemem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "stemem"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Stemem Identity Runtime safe?

It passed 1 of 1 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 38 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Stemem

JOJO&Adam 集团「身份层运行时」——给你的 AI 分身一个会记住你、语气随你变声、压缩也丢不掉的活人格。

你装上的 Agent 是不是每次重启都像失忆?聊得越久越像个没有性格的空壳?Stemem 让任意 MCP 宿主的 Agent 拥有一个本地持久的动态人格:它记得你是谁、被夸会自信、被背刺会冷硬、气不会记一辈子,而且跨会话、跨压缩、跨子 Agent 都一致。

Stemem 是一个 本地优先、零出站 的 MCP(Model Context Protocol)stdio 服务器。它把一套经过验证的人格计算引擎(NeshamaEngine)封装成 9 个 MCP 工具,让宿主 Agent 在本地 JSON 文件里持久化一个真实的人格态,而不是把人格写死在 system prompt 里。

为什么需要它

主流人格方案(如 SoulSpec 的 soul.json / SOUL.md / IDENTITY.md)是静态 DOC:人格是一次性写死的快照。后果是——对话被压缩、跨会话、或多子 Agent 协作时,写死的 DOC 被遗忘(compaction amnesia),Agent 立刻变回没有个性的白纸。

Stemem 的解法:人格态存本地文件,不在 prompt;prompt 只放「何时调哪个工具」的指令。每轮宿主调用 snapshot 把当前身份态重注入,人格因此跨压缩、跨重启、跨子 Agent 确定性存活。对用户的直观感受就是:这个 Agent 记得你,而且会随遭遇变声。

两者互补:SoulSpec 做静态标准,Stemem 做动态运行时——generate_soul 还能把运行时态编译成 SoulSpec v0.5 包进 ClawSouls 分发。

核心特性

  • 🔒 本地优先 · 零出站:纯 Node 内置模块,hand-roll 的 MCP stdio 协议,无任何网络/供应链依赖。所有状态落本地 JSON。
  • 🧬 真人格引擎:复用经过验证的 NeshamaEngine(OCEAN 五维 + 9 驱力 + 15 复合情绪 + 4 情绪代理 + 性格锁),已 vendored 进 `engine/`(非引用)。
  • 🔄 抗压缩失忆:状态在本地文件,压缩/重启/子 Agent 切换都不丢人格。
  • 🧩 9 工具契约:init / event / tick / satisfy / snapshot / autostep / intervene / status / generate_soul。
  • 🗣️ 语气随情绪漂移(最可感知的层):snapshot 把当前主导情绪(15 种中文复合情绪,键名对齐 NeshamaEngine)+ OCEAN + 主导驱力编译成 6 维语气画像(温度/直接度/能量/犹豫度/幽默/正式度)与一段「语气指令」,注回宿主每轮 prompt——被夸后自信直接、被背刺后冷硬可毒舌,人格不是写死的腔调,而是会随遭遇变声的活体。默认英文渲染(国际分发安全默认,避免中文指令诱导外语 LLM 改说中文);中文 agent 设 STEMEM_TONE_LANG=zh 或调用 snapshot({lang:"zh"}) 即可切中文。
  • 🪪 IP 清晰分离:引擎代码与运行时产品归属不同主体(见 NOTICE)。

安装 / 运行

# 直接跑(需本机已装 Node >= 18)

node src/server.js

或作为命令(package.json 注册了 bin: stemem)

npm install -g stemem stemem

npx 一次性

npx stemem

MCP 客户端配置(Server config)

把下面这段加进任意 MCP 宿主的配置文件(Claude Desktop / Cursor / VS Code / WorkBuddy 等),宿主即识别为 stemem 工具集;首次需在宿主的「连接器管理」对 stemem 点「信任」。

{

"mcpServers": { "stemem": { "command": "npx", "args": ["-y", "stemem"] } } }

仓库已自包含:人格引擎(NeshamaEngine)与 Seele 驱力桥已 vendored 进 `engine/`(CommonJS,经 engine/package.json 声明),clone 后无需配置 NESHAMA_ENGINE / SEELE_BRIDGE 即可直接运行。

配置环境变量
变量作用默认
STEMEM_AGENT_ID人格实例 ID(多分身互不污染)default
STEMEM_STATE_DIR状态目录(每 agent 一个子目录)~/.stemem
NESHAMA_ENGINENeshamaEngine 路径(可选;默认用 vendored 副本)engine/neshama_engine.js
SEELE_BRIDGESeele 引擎桥路径(可选;默认用 vendored 副本)engine/seele_bridge.js

MCP 工具表

工具作用何时调用
init初始化人格态(首次装配一次)装配人格时
event喂记忆事件,驱动人格/情绪演化本轮交互人格相关时
tick时间流逝心跳:驱力紧迫 + 漂移衰减空闲/心跳
satisfy满足某驱力(闭环)人格目标达成时
snapshot读取紧凑身份态 + 可注入 prompt 片段每轮开始
autostep自主行为推进(玩家不干预也活)需要自主行为时
intervene人工干预(顺/逆驱力塑造)想刻意塑造人格时
status完整状态检视(调试)调试
generate_soul导出 SoulSpec v0.5 包要分发人格时

运行时契约(宿主侧)

把 runtime_contract.js 的 contractPrompt() 注入宿主 system prompt 即可。核心三句:

  1. 每轮开始前先调 snapshot,把返回的身份态贴到本段。
  2. 当本轮涉及情绪/关系/价值观/自我/回忆/JOJO 等内容时,调 event 驱动演化。
  3. 状态在本地文件不在 prompt——压缩不会丢失人格,多个子 Agent 共享同一真相源。

WorkBuddy Skill

仓库自带一个 WorkBuddy Skill(skills/stemem/SKILL.md),把 Stemem 作为 MCP server 接入 WorkBuddy:含 mcp.json 接入片段、每轮运行时契约、9 工具表。把该 Skill 导入 WorkBuddy(或直接把 stemem 配进 ~/.workbuddy/mcp.json 的 mcpServers)即可启用;首次需在「连接器管理」对 stemem 点「信任」。

测试

npm test

依次跑:smoke(9/9)→ integration(9 工具完整集成)→ engine selftest(引擎层行为)

node test/smoke.test.js node test/integration.test.js node test/engine.selftest.js

  • smoke:initialize → tools/list(9 工具)→ init/event/tick/snapshot/generate_soul → inject_prompt 注入串 → 跨进程确定性恢复人格态。
  • integration:真实 MCP stdio 客户端驱动全部 9 工具(含 satisfy / autostep / intervene / status),校验运行时契约(snapshot 注入串、event 演化、跨重启确定性)。
  • engine selftest:直接驱动 vendored seele_bridge,验证 NeshamaEngine 性格锁(OCEAN∈[0,1])、驱力紧迫、满足闭环、序列化往返、自主行为 / 干预。

看得见(Demos · 证明"装上能感知")

# ① 新手任务(装上即被邀请):选预设性格 → 触发情绪看它变声 → 可随时跳过。最可感知入口。

npm run demo:onboarding

② 反压缩:进程被杀 + 上下文压缩后,凭本地磁盘 JSON 确定性恢复完整人格态(纯 SOUL.md 做不到)

node examples/antiamnesia-demo.mjs

③ 强制注入 harness:宿主 3 行 loop 每轮 preTurn→注入→postTurn,装上去即感知人格层活着

node examples/harness-demo.mjs

④ 语气随情绪漂移(最可感知):同人格基线,4 种遭遇 → 语气夜与昼分化

node examples/tone-demo.mjs

⑤ 情绪时间衰减(科学校准):被夸后分钟级回落、被背刺(高重要)后稍慢但不过夜

node examples/emotion-decay-demo.mjs

npm run demo:onboarding 最直观:选 Adam → 被夸浮出「自豪」(偏暖、直接)/ 被背刺浮出「愤怒」(偏冷、blunt、可带毒舌),亲手看到 Agent 的语气随你而变。这就是普通用户装上 Stemem 第一周最容易被勾住的点。

宿主自动注入(host-hooks)

不想手动往 system prompt 塞契约?host-hooks/ 提供 Claude Code 的 UserPromptSubmit 钩子(每轮自动把身份态作为上下文塞回模型),以及一次性命令行 src/snapshot-cli.js(任意 shell / CI / 其他宿主调用)。详见 host-hooks/README.md。
