Accessibility · SetAccessibility

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

Read the device's accessibility settings, or change one for the rest of the session: reduce_motion, bold_text, increase_contrast, reduce_transparency, button_shapes, differentiate_without_color, invert_colors, grayscale, and text size — text_size, a named category, on iOS, and text_scale, a number, on Android. These call app_accessibility.

Accessibility​

public IDictionary<string, string> Accessibility()
public string Accessibility(string setting)

Every accessibility setting the device has, by name — reduce_motion, bold_text, increase_contrast and the rest. A setting the platform lacks is absent.

One accessibility setting.

SetAccessibility​

public string SetAccessibility(string setting, string value)

Changes one accessibility setting for the rest of the session and returns its new value, confirmed by reading it back; the device is put back as it was when the session ends. A switch takes "on" or "off"; text_size a category (iOS); text_scale a number such as "1.3" (Android). A real iPhone refuses. Discards the refs from the last map.

Examples​

Read every accessibility setting​

foreach (var setting in device.Accessibility())
    Console.WriteLine($"{setting.Key} = {setting.Value}");

The same call from the command line, mobium accessibility, printed on an Android 15 emulator:

reduce_motion                off
bold_text                    off
increase_contrast            off
invert_colors                off
grayscale                    off
text_scale                   1.0

Turn bold text on for the session​

device.SetAccessibility("bold_text", "on");

The same call from the command line, mobium accessibility bold_text on, printed on an Android 15 emulator:

bold_text on (was off) — put back when the session ends
