 - `host.connections:read` 允许通过 `window.dbxPlugin.getConnections()` 或 `window.dbxPlugin.connections.list()` 获取当前所有已配置连接的只读脱敏信息（见 [连接信息读取](#连接信息读取)）。
 - `host.network:https://host[:port]` 声明浏览器可访问的 HTTPS origin，DBX 将它加入 CSP 的 `connect-src`；最多 8 个，不允许路径、通配符或 Token。仍受目标服务 CORS 规则约束。该权限不是原生 Sidecar 的网络防火墙。
+- `host.openUrl:http(s)://host[:port]` 允许请求打开指定站点，最多 8 个精确 origin；与网络权限独立，不允许路径、凭据、通配符或尾部斜杠。使用标准化的 `URL.origin`（默认端口应省略）；IPv6 地址使用方括号。
+
 - `backend.transport` 默认是 `stdio-jsonl`；需要二进制帧时使用 `stdio-framed`，并同时声明 `host.binary`。
 - `backend.executable`、`ui.root` 和 `ui.entry` 必须指向包内文件；带原生后端的包必须为每个目标平台提供对应可执行文件。
 
+### 打开外部网址
+

+
+```js
+if (window.dbxPlugin.capabilities?.openUrl) {
+  const { opened } = await window.dbxPlugin.openUrl("https://dbxio.com/cn/docs/plugins");
+}
+```
+
+每次请求都由 DBX 显示插件名称和完整目标网址，只有用户在宿主确认后才打开。Web / Docker 通过宿主的可信链接点击打开新标签页，桌面端使用系统浏览器；取消或关闭工作台返回 `{ opened: false }`，非法网址或未声明站点会拒绝请求。同一工作台同时只接受一个待确认请求。`opened: true` 表示已发起打开，不代表目标网页成功加载。
+
+接口只接受不带用户名、密码的 HTTP / HTTPS URL，最长 4,096 字符；不支持 `javascript:`、`file:` 等协议。iframe 仍保留 `sandbox="allow-scripts"`，不会获得任意弹窗、顶层导航或网络访问能力。旧宿主可能在安装时拒绝新权限；宿主或 SDK Dev Host 没有 `capabilities.openUrl` 时应隐藏入口，不要探测调用。
+
 ### Connection Provider
 
 连接 Provider 负责声明连接表单，DBX 负责渲染表单和保存生命周期；插件只处理自己的连接协议。`binding` 决定字段语义：`config` 写入外部配置，`secret` 写入 Secret Store，`name`、`host`、`port`、`username`、`password`、`database` 映射到标准连接字段。

 - `host.data:read` allows `window.dbxPlugin.queryData` to run one read-only SQL statement on a connection the user granted to the plugin (see [Read-only Data Queries](#read-only-data-queries)). Every connection needs the user's consent; it never grants writes, DDL, or reconnects.
 - `host.connections:read` allows `window.dbxPlugin.getConnections()` or `window.dbxPlugin.connections.list()` to read secret-free summary metadata for all configured connections (see [Connection Enumeration](#connection-enumeration)).
 - `host.network:https://host[:port]` declares a browser-accessible HTTPS origin added to CSP `connect-src`; at most eight origins are allowed, with no paths, wildcards, or tokens. The service's CORS rules still apply. This permission is not a native Sidecar network firewall.
+- `host.openUrl:http(s)://host[:port]` permits requesting navigation to up to eight exact origins. It is independent of network access and rejects paths, credentials, wildcards, and trailing slashes. Use the canonical `URL.origin` (omit default ports); bracket IPv6 addresses.
+
 - `backend.transport` defaults to `stdio-jsonl`. Use `stdio-framed` for binary frames and declare `host.binary` as well.
 - `backend.executable`, `ui.root`, and `ui.entry` must point to package files. Native packages need a matching executable for every target.
 
+### Open External URLs
+
+Declare, for example, `"host.openUrl:https://dbxio.com"` in the manifest, then call:
+
+```js
+if (window.dbxPlugin.capabilities?.openUrl) {
+  const { opened } = await window.dbxPlugin.openUrl("https://dbxio.com/en/docs/plugins");
+}
+```
+
+Every request displays the plugin name and complete destination in trusted DBX UI. Only explicit host approval opens it. Web / Docker uses a trusted host link click to open a new tab; desktop uses the system browser. Cancellation or workbench teardown returns `{ opened: false }`; invalid URLs and undeclared origins reject. Only one pending consent request is allowed per workbench. `opened: true` acknowledges initiation, not successful page loading.
+
+Only HTTP / HTTPS URLs without credentials are accepted, up to 4,096 characters. Protocols such as `javascript:` and `file:` are rejected. The iframe keeps `sandbox="allow-scripts"` without arbitrary popups, top navigation, or networking. Older hosts may reject the new permission during installation. Hide the action on hosts and SDK Dev Host where `capabilities.openUrl` is absent rather than probing the API.
+
 ### Connection Providers
 
 A connection provider declares a form; DBX renders the form and owns the connection lifecycle, while the plugin handles its protocol. `binding` gives a field its meaning: `config` is persisted as external configuration, `secret` goes to the Secret Store, and `name`, `host`, `port`, `username`, `password`, and `database` map to standard connection fields.
