一个给提供给Claude 用的长期情绪记忆系统。基于 Russell 效价/唤醒度坐标打标,Obsidian 做存储层,MCP 接入,带遗忘曲线。
A long-term emotional memory system for Claude. Tags memories using Russell's valence/arousal coordinates, stores them as Obsidian-compatible Markdown, connects via MCP, and has a forgetting curve.
Claude 没有跨对话记忆。每次对话结束,之前聊过的所有东西都会消失。
Ombre Brain 给了它一套持久记忆——不是那种冷冰冰的键值存储,而是带情感坐标的、会自然衰减的、像人类记忆一样会遗忘和浮现的系统。
Claude has no cross-conversation memory. Everything from a previous chat vanishes once it ends.
Ombre Brain gives it persistent memory — not cold key-value storage, but a system with emotional coordinates, natural decay, and forgetting/surfacing mechanics that loosely mimic how human memory works.
核心特点 / Key features:
情感坐标打标 / Emotional tagging: 每条记忆用 Russell 环形情感模型的 valence(效价)和 arousal(唤醒度)两个连续维度标记。不是"开心/难过"这种离散标签。 Each memory is tagged with two continuous dimensions from Russell's circumplex model: valence and arousal. Not discrete labels like "happy/sad".
自然遗忘 / Natural forgetting: 改进版艾宾浩斯遗忘曲线。不活跃的记忆自动衰减归档,高情绪强度的记忆衰减更慢。 Modified Ebbinghaus forgetting curve. Inactive memories naturally decay and archive. High-arousal memories decay slower.
权重池浮现 / Weight pool surfacing: 记忆不是被动检索的,它们会主动浮现——未解决的、情绪强烈的记忆权重更高,会在对话开头自动推送。 Memories aren't just passively retrieved — they actively surface. Unresolved, emotionally intense memories carry higher weight and get pushed at conversation start.
Obsidian 原生 / Obsidian-native: 每个记忆桶就是一个 Markdown 文件,YAML frontmatter 存元数据。可以直接在 Obsidian 里浏览、编辑、搜索。自动注入 [[双链]]。
Each memory bucket is a Markdown file with YAML frontmatter. Browse, edit, and search directly in Obsidian. Wikilinks are auto-injected.
API 降级 / API degradation: 脱水压缩和自动打标优先用廉价 LLM API(DeepSeek 等),API 不可用时自动降级到本地关键词分析——始终可用。 Dehydration and auto-tagging prefer a cheap LLM API (DeepSeek etc.). When the API is unavailable, it degrades to local keyword analysis — always functional.
官方记忆功能已经在做身份层的事了——你是谁,你有什么偏好,你们的关系是什么。那一层交给它,Ombre Brain不打算造重复的轮子。
Ombre Brain 的边界是时间里发生的事,不是你是谁。它记住的是:你们聊过什么,经历了什么,哪些事情还悬在那里没有解决。两层配合用,才是完整的。
每次新对话,Claude 从零开始——但它能从 Ombre Brain 里找回跟你有关的一切。不是重建,是接续。
Official memory already handles the identity layer — who you are, what you prefer, what your relationship is. That layer belongs there. Ombre Brain isn't trying to duplicate it.
Ombre Brain's boundary is what happened in time, not who you are. It holds conversations, experiences, unresolved things. The two layers together are what make it feel complete.
Each new conversation starts fresh — but Claude can reach back through Ombre Brain and find everything that happened between you. Not a rebuild. A continuation.

5 个 MCP 工具 / 5 MCP tools:
| 工具 Tool | 作用 Purpose |
|-----------|-------------|
| breath | 浮现或检索记忆。无参数=推送未解决记忆;有参数=关键词+情感检索 / Surface or search memories |
| hold | 存储单条记忆,自动打标+合并相似桶 / Store a single memory with auto-tagging |
| grow | 日记归档,自动拆分长内容为多个记忆桶 / Diary digest, auto-split into multiple buckets |
| trace | 修改元数据、标记已解决、删除 / Modify metadata, mark resolved, delete |
| pulse | 系统状态 + 所有记忆桶列表 / System status + bucket listing |
buckets/)
An Obsidian vault (optional — without one, it uses a local buckets/ directory)git clone https://github.com/P0lar1zzZ/Ombre-Brain.git
cd Ombre-Brain
python -m venv .venv
source .venv/bin/activate # Windows: .venv\Scripts\activate
pip install -r requirements.txt
复制配置文件并按需修改 / Copy config and edit as needed:
cp config.example.yaml config.yaml
如果你要用 API 做脱水压缩和自动打标(推荐,效果好很多),设置环境变量: If you want API-powered dehydration and tagging (recommended, much better quality):
export OMBRE_API_KEY="your-api-key"
支持任何 OpenAI 兼容 API。在 config.yaml 里改 base_url 和 model 就行。
Supports any OpenAI-compatible API. Just change base_url and model in config.yaml.
在 Claude Desktop 配置文件中添加(macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):
Add to your Claude Desktop config:
{
"mcpServers": {
"ombre-brain": {
"command": "python",
"args": ["/path/to/Ombre-Brain/server.py"],
"env": {
"OMBRE_API_KEY": "your-api-key"
}
}
}
}
需要 HTTP 传输 + 隧道。可以用 Docker: Requires HTTP transport + tunnel. Docker setup:
echo "OMBRE_API_KEY=your-api-key" > .env
docker-compose up -d
docker-compose.yml 里配好了 Cloudflare Tunnel。你需要自己在 ~/.cloudflared/ 下放凭证和路由配置。
The docker-compose.yml includes Cloudflare Tunnel. You'll need your own credentials under ~/.cloudflared/.
在 config.yaml 里设置 buckets_dir:
Set buckets_dir in config.yaml:
buckets_dir: "/path/to/your/Obsidian Vault/Ombre Brain"
不设的话,默认用项目目录下的 buckets/。
If not set, defaults to buckets/ in the project directory.
所有参数在 config.yaml(从 config.example.yaml 复制)。关键的几个:
All parameters in config.yaml (copy from config.example.yaml). Key ones:
| 参数 Parameter | 说明 Description | 默认 Default |
|---|---|---|
| transport | stdio(本地)/ streamable-http(远程)| stdio |
| buckets_dir | 记忆桶存储路径 / Bucket storage path | ./buckets/ |
| dehydration.model | 脱水用的 LLM 模型 / LLM model for dehydration | deepseek-chat |
| dehydration.base_url | API 地址 / API endpoint | https://api.deepseek.com/v1 |
| decay.lambda | 衰减速率,越大越快忘 / Decay rate | 0.05 |
| decay.threshold | 归档阈值 / Archive threshold | 0.3 |
| merge_threshold | 合并相似度阈值 (0-100) / Merge similarity | 75 |
敏感配置用环境变量: Sensitive config via env vars:
OMBRE_API_KEY — LLM API 密钥OMBRE_TRANSPORT — 覆盖传输方式OMBRE_BUCKETS_DIR — 覆盖存储路径$$final_score = time_weight \times base_score$$
$$base_score = Importance \times activation_count^{0.3} \times e^{-\lambda \times days} \times (base + arousal \times boost)$$
时间系数(乘数,优先级最高)/ Time weight (multiplier, highest priority):
| 距今天数 Days since active | 时间系数 Weight |
|---|---|
| 0–1 天 | 1.0 |
| 第 2 天 | 0.9 |
| 之后每天约降 10% | max(0.3, 0.9 × e^{-0.2197 × (days-2)}) |
| 7 天后稳定 | ≈ 0.3(不归零)|
importance: 1-10,记忆重要性 / memory importanceactivation_count: 被检索的次数,越常被想起衰减越慢 / retrieval count; more recalls = slower decaydays: 距上次激活的天数 / days since last activationarousal: 唤醒度,越强烈的记忆越难忘 / arousal; intense memories are harder to forgetpinned=true 的桶:不衰减、不合并、importance 锁定 10 / pinned buckets: never decay, never merge, importance locked at 10CLAUDE_PROMPT.md 是写给 Claude 看的使用说明。放到你的 system prompt 或 custom instructions 里就行。
CLAUDE_PROMPT.md is the usage guide written for Claude. Put it in your system prompt or custom instructions.
| 脚本 Script | 用途 Purpose |
|---|---|
| write_memory.py | 手动写入记忆,绕过 MCP / Manually write memories, bypass MCP |
| migrate_to_domains.py | 迁移平铺文件到域子目录 / Migrate flat files to domain subdirs |
| reclassify_domains.py | 基于关键词重分类 / Reclassify by keywords |
| reclassify_api.py | 用 API 重打标未分类桶 / Re-tag uncategorized buckets via API |
| test_smoke.py | 冒烟测试 / Smoke test |
⚠️ 免费层不可用:Render 免费层不支持持久化磁盘,服务重启后记忆数据会丢失,且会在无流量时休眠。必须使用 Starter($7/mo)或以上才能正常使用。 Free tier won't work: Render free tier has no persistent disk — all memory data is lost on restart. It also sleeps on inactivity. Starter plan ($7/mo) or above is required.

OMBRE_API_KEY:任何 OpenAI 兼容 API 的 key,不填则自动降级为本地关键词提取OMBRE_BASE_URL:API 地址,支持任意 OpenAI 化地址,如 https://api.deepseek.com/v1 / http://123.1.1.1:7689/v1 / http://your-ollama:11434/v1/opt/render/project/src/bucketshttps://<你的服务名>.onrender.com/mcprender.yaml is included. After clicking the button:
OMBRE_API_KEY: any OpenAI-compatible key; omit to fall back to local keyword extractionOMBRE_BASE_URL: any OpenAI-compatible endpoint, e.g. https://api.deepseek.com/v1, http://123.1.1.1:7689/v1, http://your-ollama:11434/v1/opt/render/project/src/bucketshttps://<your-service>.onrender.com/mcp💡 Zeabur 的定价模式:Zeabur 是「买 VPS + 平台托管」,你先购买一台服务器(最低腾讯云新加坡 $2/mo、火山引擎 $3/mo),Volume 直接挂在该服务器上,数据天然持久化,无丢失问题。另需订阅 Zeabur 管理方案(Developer $5/mo),总计约 $7-8/mo 起。 Zeabur pricing model: You buy a VPS first (cheapest: Tencent Cloud Singapore ~$2/mo, Volcano Engine ~$3/mo), then add Zeabur's Developer plan ($5/mo) for management. Volumes mount directly on your server — data is always persistent, no cold-start data loss. Total ~$7-8/mo minimum.
