-# Secrets CLI — AGENTS.md

-跨设备密钥与配置管理 CLI 工具，将 refining / ricnsmart 两个项目的服务器信息、服务凭据存储到 PostgreSQL 18，供 AI 工具读取上下文。
+本仓库为 **MCP SaaS**：`secrets-core`（业务与持久化）+ `secrets-mcp`（Streamable HTTP MCP、Web、OAuth、API Key）。对外入口见 `crates/secrets-mcp`。
+
+## 提交 / 发版硬规则（优先于下文）
+
+1. 涉及 `crates/**`、根目录 `Cargo.toml`/`Cargo.lock`、`secrets-mcp` 行为变更的提交，默认视为**需要发版**，除非明确说明「本次不发版」。
+2. 发版前检查 `crates/secrets-mcp/Cargo.toml` 的 `version`，再查 tag：`git tag -l 'secrets-mcp-*'`。
+3. 若当前版本对应 tag 已存在，默认允许复用现有 tag 继续构建；仅在需要新的发布版本时再 bump `version` 并 `cargo build` 同步 `Cargo.lock`。
+4. 提交前优先运行 `./scripts/release-check.sh`（版本/tag + `fmt` + `clippy --locked` + `test --locked`）。

-# 添加服务器
-secrets add -n refining --kind server --name i-uf63f2uookgs5uxmrdyc \
-  --tag aliyun --tag shanghai \
-  -m ip=47.117.131.22 -m desc="Aliyun Shanghai ECS" \
-  -s username=root -s ssh_key=@./keys/voson_shanghai_e.pem
+与迁移脚本一致：`audit_log`、`entries_history`、`secrets_history` 用于审计与时间旅行恢复；字段定义见 `crates/secrets-core/src/db.rs` 内 `migrate` SQL。
 
-# 添加服务凭据
-secrets add -n refining --kind service --name gitea \
-  --tag gitea \
-  -m url=https://gitea.refining.dev \
-  -s token=<token>
+### 字段职责
 
-# 搜索含 mqtt 的所有记录
-secrets search -q mqtt
+| 字段 | 含义 | 示例 |
+|------|------|------|
+| `namespace` | 隔离空间 | `refining` |
+| `kind` | 记录类型 | `server`, `service`, `key` |
+| `name` | 标识名 | `gitea`, `i-example0…` |
+| `tags` | 标签 | `["aliyun","prod"]` |
+| `metadata` | 明文描述 | `ip`、`url`、`key_ref` |
+| `secrets.field_name` | 加密字段名（明文） | `token`, `ssh_key` |
+| `secrets.encrypted` | 密文 | AES-GCM |
 
-# 查看 refining 的全部服务配置（显示 secrets）
-secrets search -n refining --kind service --show-secrets
+### PEM 共享（`key_ref`）
 
-# 按 tag 筛选
-secrets search --tag hongkong
-
-# 只更新一个 IP（不影响其他 metadata/secrets/tags）
-secrets update -n refining --kind server --name i-uf63f2uookgs5uxmrdyc \
-  -m ip=10.0.0.1
-
-# 给一条记录新增 tag 并轮换密码
-secrets update -n refining --kind service --name gitea \
-  --add-tag production \
-  -s token=<new-token>
-
-# 移除一个废弃的 metadata 字段
-secrets update -n refining --kind service --name mqtt \
-  --remove-meta old_port
-```
+将共享 PEM 存为 `kind=key` 的 entry；其它记录在 `metadata.key_ref` 指向该 key 的 `name`。更新 key 记录后，引用方通过服务层解析合并逻辑即可使用新密钥（实现见 `secrets_core::service`）。
 
 ## 代码规范
 
-- 错误处理：统一使用 `anyhow::Result`，不用 `unwrap()`
-- 异步：全程 `tokio`，数据库操作 `sqlx` async
-- SQL：使用 `sqlx::query` / `sqlx::query_as` 绑定参数，禁止字符串拼接（搜索的动态 WHERE 子句除外，需使用参数绑定 `$1/$2`）
-- 新增 `kind` 类型时：只需在 `add` 调用时传入，无需改代码
-- 字段命名：CLI 短标志 `-n`=namespace，`-m`=meta，`-s`=secret，`-q`=query，`-v`=verbose
-- 日志：用户可见输出用 `println!`；调试/运维信息用 `tracing::debug!`/`info!`/`warn!`/`error!`
-- 审计：`add`/`update`/`delete` 成功后调用 `audit::log()`，写入 `audit_log` 表；失败只 warn 不中断
+- 错误：业务层 `anyhow::Result`，避免生产路径 `unwrap()`。
+- 异步：`tokio` + `sqlx` async。
+- SQL：`sqlx::query` / `query_as` 参数绑定；动态 WHERE 仍须用占位符绑定。
+- 日志：运维用 `tracing`；面向用户的 Web 响应走 axum handler。
+- 审计：写操作成功后尽量 `audit::log_tx`；失败可 `warn`，不掩盖主错误。
+- 加密：密钥由用户密码短语通过 **PBKDF2-SHA256（600k 次）** 在客户端派生，服务端只存 `key_salt`/`key_check`/`key_params`，不持有原始密钥。Web 客户端在浏览器本地完成加解密；MCP 客户端通过 `X-Encryption-Key` 请求头传递密钥，服务端临时解密后返回明文。
+- MCP：tools 参数与 JSON Schema（`schemars`）保持同步，鉴权以请求扩展中的用户上下文为准。
 
-## 提交前检查（必须全部通过）
-
-每次提交代码前，请在本地依次执行以下检查，**全部通过后再 push**：
-
-### 1. 版本号（按需）
-
-若本次改动需要发版，请先确认 `Cargo.toml` 中的 `version` 已提升，避免 CI 打出的 Tag 与已有版本重复。可通过 git tag 判断：
+## 提交前检查
 
 ```bash
-# 查看当前 Cargo.toml 版本
-grep '^version' Cargo.toml
-
-# 查看是否已存在该版本对应的 tag（CI 使用格式 secrets-<version>）
-git tag -l 'secrets-*'
+./scripts/release-check.sh
 ```
 
-若当前版本已被 tag（例如已有 `secrets-0.1.0` 且 `Cargo.toml` 仍为 `0.1.0`），则应在 `Cargo.toml` 中 bump 版本号后再提交，以便 CI 自动打新 Tag 并发布 Release。
-
-### 2. 格式、Lint、测试
+或手动：
 
 ```bash
-cargo fmt -- --check   # 格式检查（不通过则运行 cargo fmt 修复）
-cargo clippy -- -D warnings  # Lint 检查（消除所有 warning）
-cargo test             # 单元/集成测试
+cargo fmt -- --check
+cargo clippy --locked -- -D warnings
+cargo test --locked
 ```
 
-或一次性执行：
+发版前确认未重复 tag：
 
 ```bash
-cargo fmt -- --check && cargo clippy -- -D warnings && cargo test
+grep '^version' crates/secrets-mcp/Cargo.toml
+git tag -l 'secrets-mcp-*'
 ```
 
 ## CI/CD
 
-- Gitea Actions（runner: debian）
-- 触发：`src/**`、`Cargo.toml`、`Cargo.lock` 变更推送到 main
-- 构建目标：`x86_64-unknown-linux-musl`（静态链接，无 glibc 依赖）
-- 新版本自动打 Tag（格式 `secrets-<version>`）并上传二进制到 Gitea Release
-- 通知：飞书 Webhook（`vars.WEBHOOK_URL`）
-- 所需 secrets/vars：`RELEASE_TOKEN`（Release 上传，Gitea PAT）、`vars.WEBHOOK_URL`（通知，可选）
+- **触发**：任意分支 `push`，且路径含 `crates/**`、`deploy/**`、根目录 `Cargo.toml`、`Cargo.lock`（见 `.gitea/workflows/secrets.yml`）。
+- **版本与 tag**：从 `crates/secrets-mcp/Cargo.toml` 读版本；若远程已存在同名 `secrets-mcp-<version>` tag，则复用现有 tag 继续构建；否则由 CI 创建并推送该 tag。
+- **质量与构建**：`fmt` / `clippy --locked` / `test --locked` → `x86_64-unknown-linux-musl` 发布构建 `secrets-mcp`。
+- **Release（可选）**：`secrets.RELEASE_TOKEN`（Gitea PAT）用于创建草稿 Release、上传 `tar.gz` + `.sha256`、构建成功后发布；未配置则跳过 API Release，仅 tag + 构建。
+- **部署（可选）**：仅 `main`、`feat/mcp`、`mcp` 分支在构建成功时跑 `deploy-mcp`；需 `vars.DEPLOY_HOST`、`vars.DEPLOY_USER`、`secrets.DEPLOY_SSH_KEY`。勿把 OAuth/DB 等写进 workflow，用 `deploy/.env.example` 在目标机配置。
+- **Secrets 写法**：Actions **secrets 须为原始值**（PEM、PAT 明文），**勿** base64；否则 SSH/Release 会失败。**勿**在 CI 中保存 `GOOGLE_CLIENT_SECRET`、DB 密码。
+- **通知**：`vars.WEBHOOK_URL`（可选，飞书）。
 
-## 环境变量
+## 环境变量（secrets-mcp）
 
 | 变量 | 说明 |
 |------|------|
-| `RUST_LOG` | 日志级别，如 `secrets=debug`、`secrets=trace`（默认 warn） |
-| `USER` | 审计日志 actor 字段来源，Shell 自动设置，通常无需手动配置 |
+| `SECRETS_DATABASE_URL` | **必填**。PostgreSQL URL。 |
+| `BASE_URL` | 对外基址；OAuth 回调 `${BASE_URL}/auth/google/callback`。 |
+| `SECRETS_MCP_BIND` | 监听地址，默认 `0.0.0.0:9315`。 |
+| `GOOGLE_CLIENT_ID` / `GOOGLE_CLIENT_SECRET` | 可选；仅运行时配置。 |
+| `RUST_LOG` | 如 `secrets_mcp=debug`。 |
+| `USER` | 若写入审计 `actor`，由运行环境提供。 |
 
-数据库连接通过 `secrets config set-db` 持久化到 `~/.config/secrets/config.toml`，不支持环境变量。
+> `SERVER_MASTER_KEY` 已不再需要。新架构下密钥由用户密码短语在客户端派生，服务端不持有。

 ## 数据模型
 
-单张 `secrets` 表，首次连接自动建表；同时自动创建 `audit_log` 表，记录所有写操作。
+主表 **`entries`**（`namespace`、`kind`、`name`、`tags`、`metadata`，多租户时带 `user_id`）+ 子表 **`secrets`**（每行一个加密字段：`field_name`、`encrypted`）。另有 `entries_history`、`secrets_history`、`audit_log`，以及 **`users`**（含 `key_salt`、`key_check`、`key_params`）、**`oauth_accounts`**、**`api_keys`**。首次连库自动迁移建表。
 
-| 字段 | 说明 |
-|------|------|
-| `namespace` | 一级隔离，如 `refining`、`ricnsmart` |
-| `kind` | 记录类型，如 `server`、`service`（可自由扩展） |
-| `name` | 人类可读唯一标识 |
-| `tags` | 多维标签，如 `["aliyun","hongkong"]` |
-| `metadata` | 明文描述信息（ip、desc、domains 等） |
-| `encrypted` | 敏感凭据（ssh_key、password、token 等），MVP 阶段明文存储，预留加密字段 |
+| 位置 | 字段 | 说明 |
+|------|------|------|
+| entries | namespace | 一级隔离，如 `refining`、`ricnsmart` |
+| entries | kind | `server`、`service`、`key` 等（可扩展） |
+| entries | name | 人类可读标识 |
+| entries | metadata | 明文 JSON（ip、url、`key_ref` 等） |
+| secrets | field_name | 明文字段名，便于 schema 展示 |
+| secrets | encrypted | AES-GCM 密文（含 nonce） |
+| users | key_salt | PBKDF2 salt（32B），首次设置密码短语时写入 |
+| users | key_check | 派生密钥加密已知常量，用于验证密码短语 |
+| users | key_params | 派生算法参数，如 `{"alg":"pbkdf2-sha256","iterations":600000}` |
 
-`-m` / `--meta` 写入 `metadata`，`-s` / `--secret` 写入 `encrypted`，`value=@file` 从文件读取内容。
+### PEM 共享（`key_ref`）
+
+同一 PEM 可被多条 `server` 记录引用：将 PEM 存为 `kind=key` 的 entry，在服务器条目的 `metadata.key_ref` 中写 key 的名称；轮换时只更新 key 对应记录即可。
 
 ## 审计日志
 
-`add`、`update`、`delete` 操作成功后自动向 `audit_log` 表写入一条记录，包含操作类型、操作对象和变更摘要（不含 secret 值）。操作者取自 `$USER` 环境变量。
+`add`、`update`、`delete` 等写操作写入 **`audit_log`**（操作类型、对象、摘要，不含 secret 明文）。

 ## CI/CD（Gitea Actions）
 
-推送 `main` 分支时自动：fmt/clippy 检查 → musl 构建 → 创建 Release 并上传二进制。
+见 [`.gitea/workflows/secrets.yml`](.gitea/workflows/secrets.yml)。
 
-**首次使用需配置 Actions 变量和 Secrets：**
+- **触发**：任意分支 `push`，且变更路径包含 `crates/**`、`deploy/**`、根目录 `Cargo.toml` / `Cargo.lock`。
+- **流水线**：解析 `crates/secrets-mcp/Cargo.toml` 版本 → 若 `secrets-mcp-<version>` 的 tag 已存在则**复用现有 tag 继续构建**，否则自动打 tag → `cargo fmt` / `clippy --locked` / `test --locked` → 交叉编译 `x86_64-unknown-linux-musl` 的 `secrets-mcp`。
+- **Release（可选）**：配置仓库 Secret `RELEASE_TOKEN`（Gitea PAT，明文勿 base64）时，会通过 API 创建**草稿** Release、在 Linux 构建成功后上传 `tar.gz` 与 `.sha256`，再自动将草稿**正式发布**；未配置则跳过创建 Release 与产物上传，仅保留 tag 与构建结果。
+- **部署（可选）**：仅在 `main`、`feat/mcp` 或 `mcp` 分支且构建成功时，若已配置 `vars.DEPLOY_HOST`、`vars.DEPLOY_USER` 与 `secrets.DEPLOY_SSH_KEY`，则 `deploy-mcp` 通过 SCP/SSH 更新目标机二进制并 `systemctl restart secrets-mcp`。
+- **通知（可选）**：`vars.WEBHOOK_URL` 为飞书 Webhook 时，构建/部署/发布节点会推送简要状态。
 
 ```bash
-# 需有 ~/.config/gitea/config.env（GITEA_URL、GITEA_TOKEN、GITEA_WEBHOOK_URL）
-./scripts/setup-gitea-actions.sh
+./scripts/setup-gitea-actions.sh   # 通过 Gitea API 写入 RELEASE_TOKEN、WEBHOOK_URL、部署相关变量等
 ```
 
-- `RELEASE_TOKEN`（Secret）：Gitea PAT，用于创建 Release 上传二进制
-- `WEBHOOK_URL`（Variable）：飞书通知，可选
