accessibility

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​

accessibility(): Promise<Record<string, string>>
accessibility(setting: string, value?: string | number | boolean): Promise<string>

Every setting by name, or one setting's value; with a value, sets it for the session.

Examples​

Read every accessibility setting​

const settings = await device.accessibility()
console.log(settings.bold_text, settings.reduce_motion)

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​

await device.accessibility('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
