Implementation Reference
- src/handlers.ts:168-201 (handler)The main handler function for the 'android_swipe' MCP tool. Validates input coordinates, calls the ADB wrapper's swipe method, and returns a success message.export async function swipeHandler( adb: ADBWrapper, args: any ): Promise<{ content: Array<{ type: string; text: string }> }> { const { startX, startY, endX, endY, duration = 300, deviceSerial } = args as SwipeArgs; if ( typeof startX !== 'number' || typeof startY !== 'number' || typeof endX !== 'number' || typeof endY !== 'number' ) { throw new Error('Invalid coordinates: all coordinates must be numbers'); } if (startX < 0 || startY < 0 || endX < 0 || endY < 0) { throw new Error('Invalid coordinates: all coordinates must be positive'); } try { await adb.swipe(startX, startY, endX, endY, duration, deviceSerial); return { content: [ { type: 'text', text: `Swipe executed from (${startX}, ${startY}) to (${endX}, ${endY}) over ${duration}ms`, }, ], }; } catch (error) { throw new Error(`Swipe failed: ${error instanceof Error ? error.message : String(error)}`); } }
- src/adb-wrapper.ts:316-339 (helper)Low-level implementation in ADBWrapper that executes the 'adb shell input swipe' command using the provided start/end coordinates and duration.async swipe( startX: number, startY: number, endX: number, endY: number, duration: number = 300, deviceSerial?: string ): Promise<void> { const device = await this.getTargetDevice(deviceSerial); await this.exec( [ 'shell', 'input', 'swipe', String(startX), String(startY), String(endX), String(endY), String(duration), ], device ); }
- src/index.ts:85-119 (schema)Input schema definition for the 'android_swipe' tool, registered in the ListToolsRequestHandler.{ name: 'android_swipe', description: 'Perform a swipe gesture between two coordinates', inputSchema: { type: 'object', properties: { startX: { type: 'number', description: 'Starting X coordinate', }, startY: { type: 'number', description: 'Starting Y coordinate', }, endX: { type: 'number', description: 'Ending X coordinate', }, endY: { type: 'number', description: 'Ending Y coordinate', }, duration: { type: 'number', description: 'Swipe duration in milliseconds (default: 300)', default: 300, }, deviceSerial: { type: 'string', description: 'Specific device serial number to target (optional)', }, }, required: ['startX', 'startY', 'endX', 'endY'], }, },
- src/index.ts:468-469 (registration)Registration of the swipeHandler in the CallToolRequestHandler switch statement.case 'android_swipe': return await swipeHandler(this.adb, args);
- src/handlers.ts:15-22 (schema)TypeScript interface defining the shape of arguments expected by the swipeHandler.interface SwipeArgs { startX: number; startY: number; endX: number; endY: number; duration?: number; deviceSerial?: string; }
