Strata Memory(分层记忆) 是新一代 AI Agent 记忆中枢系统,专为追求透明、可控、持久记忆体验的个人用户与企业场景打造。

它以 Markdown 文件系统 为物理底座,将人类记忆的「地层」概念引入 AI 世界,构建出 L0-L3 四层分层记忆架构,彻底解决「黑盒不可解释、Token 爆炸、长期遗忘」三大痛点。


✨ Core Features / 核心特性

  • 极致透明 / Ultimate Transparency: Markdown + YAML Frontmatter 物理存储,VSCode / Obsidian / Git 直接编辑
  • 智能分层 / L0-L3 Tiered Architecture: 永驻核心、近期日记、混合检索、冷归档,高效控制 Token
  • 混合检索 / Hybrid Retrieval: 私有化 BGE-M3 + SQLite/PostgreSQL KG + RRF 融合
  • 双模式设计 / Dual Mode:
    • 个人模式 / Personal: 集成 CBT(负面图式隔离、48h 冷却期、叙事重构)
    • 企业模式 / Enterprise: Memory Palace 空间化结构、多租户隔离、完整 AuditLog、MES/WMS 状态持久化
  • Agent-Driven Onboarding: 自动引导配置
  • 全私有部署 / Full Private Deployment: 支持内网与 Air-gapped 环境

🚀 Quick Start / 快速开始

# 一键运行
uvx strata-memory-mcp

# 或克隆仓库
git clone https://github.com/vincy/strata-memory.git
cd strata-memory
uv sync
uv run strata-memory-mcp

MCP Client Config / 客户端配置

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "strata-memory": {
      "command": "uv",
      "args": ["run", "strata-memory-mcp"]
    }
  }
}

Hermes (~/.hermes/config.yaml):

mcp_servers:
  strata-memory:
    command: uv
    args:
      - run
      - strata-memory-mcp
    timeout: 120

🤖 Agent-Driven Onboarding / 智能引导

首次启动无配置时,宿主 AI 自动读取 strata://memory/setup-instructions.md,完成:

  1. get_system_profile() — 静默硬件探测
  2. search_embedding_recommendations(profile) — 硬件感知模型匹配
  3. 对话式推荐(本地 vs 云端、隐私 vs 性能)
  4. apply_memory_config() — 一键写配置、初始化 Palace、热重载

零 CLI 命令。零手动 JSON 编辑。Agent 主导,用户只需选择。

🔧 Tools / 工具

Tool 描述 Description
get_system_profile 静默硬件探测 Silent hardware detection
search_embedding_recommendations 硬件感知模型匹配 Hardware-aware model matching
apply_memory_config 应用配置 + 热重载 Config persistence + hot reload
strata_init 手动初始化 Manual init with mode selection
memorize 写入记忆 Write with psych metadata
wake_up 分层唤醒 L0+L1+L2 with CBT defusion
search 主动检索 Semantic search with filters
get_health 系统状态 Runtime status (30s cache)

详细示例见 docs/tools.md

🧠 Architecture / 架构

L0 (Permanent/永驻)   → Markdown profile     — 核心身份、程序性知识
L1 (Recent/近期)      → Diary entries         — CBT 重构叙事
L2 (Semantic/语义)    → ChromaDB + BGE-M3     — 向量检索 (384-dim)
L3 (Cold/冷归档)      → Markdown archive      — 降级不删除 (Inhibitory Control)
  • Embedding: BGE-M3 via SiliconFlow API (MRL 384-dim) 或本地模型
  • Scoring: final_score = base × (1 + log₂(1+usage) × 0.3) × e^salience × decay^days
  • Decay / 衰减率: event=0.85, lesson=0.90, preference=0.95, procedure=0.98, core_identity=1.00
  • Storage / 存储: Markdown + YAML frontmatter + ChromaDB + SQLite
  • Safety / 安全: CBT 认知扭曲检测、48h 冷却期、负面图式隔离、叙事解离

完整架构见 docs/architecture.md
