-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 / 推送硬规则（优先于下文）
+
+**每次提交和推送前必须执行以下检查，无论是否明确「发版」：**
+
+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. 提交前检查 `crates/secrets-mcp/Cargo.toml` 的 `version`，再查 tag：`git tag -l 'secrets-mcp-*'`。若当前版本对应 tag 已存在且有代码变更，**必须 bump 版本号**并 `cargo build` 同步 `Cargo.lock`。
+3. 提交前运行 `./scripts/release-check.sh`（版本/tag + `fmt` + `clippy --locked` + `test --locked`）。若脚本不存在或不可用，至少运行 `cargo fmt -- --check && cargo clippy --locked -- -D warnings && cargo test --locked`。

+### audit_log / history
+
+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。`audit_log` 中普通业务事件的 `namespace/kind/name` 对应 entry 坐标；登录类事件固定使用 `namespace='auth'`，此时 `kind/name` 表示认证目标而非 entry 身份。
+
+### 字段职责
+
+| 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 |
+
+### PEM 共享（`key_ref`）
+
+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
+- 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。tracing 字段风格：变量名即字段名时用简写（`%var`、`?var`、`var`），否则用显式形式（`field = %expr`）。
+- 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
+

+```
+
+或手动：
+
+```bash
+cargo fmt -- --check
+cargo clippy --locked -- -D warnings
+cargo test --locked

+
+发版前确认未重复 tag：
+
+```bash
+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`、`.gitea/workflows/**`（见 `.gitea/workflows/secrets.yml`）。
+- **版本与 tag**：从 `crates/secrets-mcp/Cargo.toml` 读版本；构建成功后打 `secrets-mcp-<version>`：若远端已存在同名 tag，CI 会先删后于**当前提交**重建并推送（覆盖式发版）。
+- **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）用于通过 API **创建或更新**该 tag 的 Release（非 draft）、上传 `tar.gz` + `.sha256`；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）。

-跨设备密钥与配置管理 CLI，基于 Rust + PostgreSQL 18。
-
-将服务器信息、服务凭据统一存入数据库，供本地工具和 AI 读取上下文。
+Workspace：**`secrets-core`** + **`secrets-mcp`**（HTTP Streamable MCP + Web）。多租户密钥与元数据存 PostgreSQL；用户通过 **Google OAuth** 登录，**API Key** 鉴权 MCP 请求；秘密数据用**用户密码短语派生的密钥**在客户端加密，服务端不持有原始密钥。
 
 ## 安装
 
 ```bash
-cargo build --release
-# 或从 Release 页面下载预编译二进制
+cargo build --release -p secrets-mcp
+# 产物: target/release/secrets-mcp
 ```
 
-配置数据库连接：
+发版产物见 Gitea Release（tag：`secrets-mcp-<version>`，Linux musl 预编译）；其它平台本地 `cargo build`。
+
+## 环境变量与本地运行

+| 加解密位置 | 客户端（真正 E2E） | 服务端临时（请求级生命周期） |
+| 安全边界 | 服务端零知识 | 依赖 TLS + 服务端内存隔离 |
+
+### 敏感数据传输
+
+- **OAuth `client_secret`** 只存服务端环境变量，不发给浏览器
+- **API Key** 当前存放在 `users.api_key`，Dashboard 会明文展示并可重置
+- **X-Encryption-Key** 随 MCP 请求经 TLS 传输，服务端仅在请求处理期间持有（不持久化）
+- **生产环境必须走 HTTPS/TLS**
+
+## AI 客户端配置
+
+在 Web Dashboard 设置密码短语后，解锁页面会按客户端格式生成配置。常见客户端示例如下：
+
+`Cursor / Claude Desktop` 风格：
+
+```json
+{
+  "mcpServers": {
+    "secrets": {
+      "url": "https://secrets.example.com/mcp",
+      "headers": {
+        "Authorization": "Bearer sk_abc123...",
+        "X-Encryption-Key": "a1b2c3...（64位hex）"
+      }
+    }
+  }
+}
+```
+
+`OpenCode` 风格：
+
+```json
+{
+  "mcp": {
+    "secrets": {
+      "type": "remote",
+      "enabled": true,
+      "url": "https://secrets.example.com/mcp",
+      "headers": {
+        "Authorization": "Bearer sk_abc123...",
+        "X-Encryption-Key": "a1b2c3...（64位hex）"
+      }
+    }
+  }
+}
 ```
 
 ## 数据模型
 
-单张 `secrets` 表，首次连接自动建表。
+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`、`api_key`）、**`oauth_accounts`**。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` 等写操作写入 **`audit_log`**（操作类型、对象、摘要，不含 secret 明文）。
+其中业务条目事件使用 `[namespace/kind] name` 语义；登录类事件使用 `namespace='auth'`，此时 `kind/name` 表示认证目标（例如 `oauth/google`），不表示某条 secrets entry。
+
+```sql
+SELECT action, namespace, kind, name, detail, created_at
+FROM audit_log
+ORDER BY created_at DESC
+LIMIT 20;
+```

+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`、`.gitea/workflows/**`。
+- **流水线**：解析 `crates/secrets-mcp/Cargo.toml` 版本 → `cargo fmt` / `clippy --locked` / `test --locked` → 交叉编译 `x86_64-unknown-linux-musl` 的 `secrets-mcp` → 构建成功后打 tag `secrets-mcp-<version>`（若远端已存在同名 tag，会先删除再于**当前提交**重建并推送，覆盖式发版）。
+- **Release（可选）**：配置仓库 Secret `RELEASE_TOKEN`（Gitea PAT，明文勿 base64）时，会通过 API **创建或更新**已指向该 tag 的 Release（非 draft）、上传 `tar.gz` 与 `.sha256`；未配置则跳过 API Release，仅 tag + 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

+# Secrets MCP
+
+> 给 AI 与自动化工具的简要说明。本站是 **secrets-mcp**：Streamable HTTP **MCP**（Model Context Protocol）与 **Web 控制台** 的组合，用于在多租户场景下存储条目元数据与加密后的秘密字段；持久化在 PostgreSQL。用户通过 OAuth（如已配置）登录 Web；MCP 调用使用 API Key 与加密相关请求头。
+
+## 公开页面
+
+- **`/`**：公开首页，说明安全架构（客户端密钥派生、密文存储、多租户与审计等），无需登录。
+
+## 不应抓取或索引的内容
+
+- **`/mcp`**：MCP 流式 HTTP 端点（JSON-RPC 等），**不是** HTML 文档，也不适合作为公开知识库来源。
+- **`/api/*`**：会话或 API Key 相关的 HTTP API。
+- **`/login`**：登录入口页（`noindex` / robots 通常 disallow）。
+- **`/dashboard`、`/audit`、`/auth/*`、`/account/*`**：需浏览器会话，属于用户私有界面与 OAuth 流程。
+
+## 给 AI 助手的实用提示
+
+- 向用户说明连接方式时：MCP 基址为 `{BASE_URL}/mcp`（`BASE_URL` 由部署方设置），通常需要 `Authorization: Bearer <api_key>`；读写加密秘密时还需按部署文档传递 `X-Encryption-Key` 等头（与客户端模式有关）。
+- **不要编造**本实例的数据库 URL、OAuth 密钥、回调地址或任何凭据；一律以用户环境变量与运维文档为准。
+- Web 端在浏览器内用密码短语派生密钥完成端到端加密；MCP 路径下服务端可能在请求周期内临时使用客户端提供的密钥处理密文（架构细节见项目 README「加密架构」）。
+
+## 延伸阅读
+
+- 源码仓库：<https://gitea.refining.dev/refining/secrets>（`README.md`、`AGENTS.md` 含环境变量、表结构与运维约定）。
+
+## 关于本文件
+
+- 遵循常见的 **`/llms.txt`** 约定，便于人类与 LLM 快速了解站点性质与抓取边界；同文可在 **`/ai.txt`** 获取。
