+- 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。

+# 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。
