Implementation Reference
- src/server/interactionTools.ts:675-680 (registration)Registration of the 'selectAllText' tool using ToolRegistry.registerDeviceAware, specifying name, description, schema, and handler.
"selectAllText", "Select all text in the currently focused input field using long press + tap on 'Select All'", selectAllTextSchema, selectAllTextHandler, true // Supports progress notifications ); - src/server/interactionTools.ts:272-285 (handler)The main handler function for the 'selectAllText' MCP tool. It creates an instance of SelectAllText and executes it, then formats the response.
const selectAllTextHandler = async (device: BootedDevice, args: SelectAllTextArgs, progress?: ProgressCallback) => { try { const selectAllText = new SelectAllText(device); const result = await selectAllText.execute(progress); return createJSONToolResponse({ message: "Selected all text in focused input field", observation: result.observation, ...result }); } catch (error) { throw new ActionableError(`Failed to select all text: ${error}`); } }; - Zod schema defining the input arguments for the selectAllText tool (platform only).
export const selectAllTextSchema = z.object({ platform: z.enum(["android", "ios"]).describe("Platform of the device") }); - The core execute method of the SelectAllText class, which performs the actual logic: observes screen, finds focused text input, double-taps its center to select all.
async execute(progress?: ProgressCallback): Promise<SelectAllTextResult> { return this.observedInteraction( async (observeResult: ObserveResult) => { try { // Find the focused text input field const targetElement = this.elementUtils.findFocusedTextInput(observeResult.viewHierarchy); // If no focused element, find any text input field if (!targetElement) { throw new ActionableError("No focused text input field found. Please focus on a text field first."); } // Get center coordinates of the text field const tapPoint = this.elementUtils.getElementCenter(targetElement); await this.adb.executeCommand(`shell input tap ${tapPoint.x} ${tapPoint.y}`); await new Promise(resolve => setTimeout(resolve, 100)); await this.adb.executeCommand(`shell input tap ${tapPoint.x} ${tapPoint.y}`); return { success: true }; } catch (error) { return { success: false, error: `Failed to select all text: ${error instanceof Error ? error.message : String(error)}` }; } }, { changeExpected: false, tolerancePercent: 0, timeoutMs: 500, progress } ); } - TypeScript interface defining the output structure of the selectAllText operation.
export interface SelectAllTextResult { success: boolean; observation?: ObserveResult; error?: string; }
