Personal Agent Memory (PAM)

中文:Personal Agent Memory(简称 PAM)是自托管的个人记忆服务。部署在一台 Linux 服务器上,你的所有设备与 Agent(Cursor、Claude Code、Codex、各类 Bot)共用同一份记忆;电脑离线时服务器照常工作。提供版本化 REST /v1 与远程 MCP(Streamable HTTP)/mcp,二者走同一领域层。密钥、密码、联系方式等私人信息不进普通记忆,而是进入可插拔的加密层(可指向外部服务器或网盘目录),记忆中只留引用。

English: Personal Agent Memory (PAM) is a self-hosted personal memory service shared by all your devices and agents. One Linux server, a versioned REST API (/v1) and a remote MCP endpoint (/mcp, Streamable HTTP) over the same domain layer. Credentials and contact data are routed to a pluggable, envelope-encrypted vault (local, external directory, or a remote blob server); memories only keep references.

包名 / 命令行:pam。旧命令 memory-hub 作为弃用别名保留一个版本。

特性

  • 四类并列记忆 kind:personal / project / knowledge / methods;salience(0–100) 与 stability 用于上下文排序。

  • 规范化、版本化 JSON 契约(docs/CONTRACT.md);SQLite 规范存储,修订、墓碑删除、变更流、outbox + 幂等索引 worker。

  • 混合检索 BM25 + 向量 + RRF;授权/过滤在每个分支一致生效;不会返回已删除/已取代内容。

  • Embedding 可内嵌也可自定义:local(内嵌 sentence-transformers,默认 intfloat/multilingual-e5-small,CPU 可跑)、http(OpenAI 兼容端点)、hash(仅测试/兜底,无语义)。换 provider 自动建新索引代。

  • 加密层:信封加密(每条 DEK + AES-256-GCM,KEK 不入库),后端可选本地加密文件库 / 外部目录(同步盘、挂载网盘)/ 外部 HTTP 服务器(只收密文);按类别路由;读取明文需 secrets:read 范围并审计。

  • 每客户端令牌(哈希存储、可撤销、kind/project/op 范围;项目受限客户端默认看不到 personal)。

  • 旧 agent-memory 导入(真实 schema 已校准)+ 无损校验;agent_memory_* 兼容工具名。

快速开始

python3 -m venv .venv
.venv/bin/pip install -e '.[dev]'          # 最小安装(hash embedding,无语义)
.venv/bin/pip install -e '.[local]'        # 推荐:内嵌本地多语种模型(首次使用时下载)
export PAM_DATA_DIR=./data
.venv/bin/pam embed doctor                 # 查看当前 provider / 维度 / 是否语义
.venv/bin/pam secrets keygen > ~/.pam-kek && chmod 600 ~/.pam-kek
export PAM_VAULT_KEK_REF=file:$HOME/.pam-kek   # 启用加密层(KEK 放在数据目录之外)
.venv/bin/pam client create my-laptop --ops read,write     # token 只显示一次
.venv/bin/pam serve --host 127.0.0.1 --port 8765
.venv/bin/pytest -q && python scripts/check_secrets.py

MCP 客户端:URL http://<host>:8765/mcp,Header Authorization: Bearer <token>。公网暴露 / HTTPS / OAuth 属于里程碑 2,目前请只在本机或可信内网使用。
