app_cookies

This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET

Read, set or clear the current WebView's cookies — the ones its page's URL is sent, HttpOnly ones included, which document.cookie cannot see. Vibium's cookies command, on a WebView: needs a web context, so switch with app_context first. "get" (the default) lists them; "set" sets each of cookies and reads the store back, so one the browser accepted and stored expired is reported, not claimed; "clear" deletes them all, or those called name. An Android app's WebViews share one cookie store, so a cookie set here is set for all of them.

Changes the device, the app or the session: readOnlyHint is false.

Arguments

Name	Type	Required	What it is
action	string: get, set, clear		get (default), set or clear.
cookies	array of object		With set: the cookies to set.
device	string		Device serial to target, e.g. "emulator-5554". Omit when only one device is running.
driver	string: uiautomator2, uiautomator, wda		Driver to use: "uiautomator2" (default for Android; fast, installs a server APK on first use), "uiautomator" (Android, installs nothing, slower, cannot type), or "wda" (WebDriverAgent: iOS simulators and iPhones).
name	string		With clear: delete only the cookies with this name.
