Implementation Reference

• src/index.ts:206-233 (handler)

  Executes the adb_device_info tool by fetching device model, Android version, and API level using ADB getprop commands and returns formatted text output.

  case "adb_device_info": {
    const { device_id } = args as {
      device_id?: string;
    };
  
    const deviceArg = device_id ? `-s ${device_id}` : "";
    
    const [model, android, api] = await Promise.all([
      execAsync(`adb ${deviceArg} shell getprop ro.product.model`),
      execAsync(`adb ${deviceArg} shell getprop ro.build.version.release`),
      execAsync(`adb ${deviceArg} shell getprop ro.build.version.sdk`),
    ]);
  
    const info = {
      model: model.stdout.trim(),
      android_version: android.stdout.trim(),
      api_level: api.stdout.trim(),
    };
  
    return {
      content: [
        {
          type: "text",
          text: `Device Information:\nModel: ${info.model}\nAndroid Version: ${info.android_version}\nAPI Level: ${info.api_level}`,
        },
      ],
    };
  }

• src/index.ts:98-111 (registration)

  Registers the adb_device_info tool in the ListToolsRequestSchema response, defining its name, description, and input schema.

    description: "Get information about a connected device",
    inputSchema: {
      type: "object",
      properties: {
        device_id: {
          type: "string",
          description: "Device ID/serial (optional, uses first device if not specified)",
        },
      },
      required: [],
    },
  },

• src/index.ts:101-110 (schema)

  Input schema definition for the adb_device_info tool, specifying optional device_id parameter.

  inputSchema: {
    type: "object",
    properties: {
      device_id: {
        type: "string",
        description: "Device ID/serial (optional, uses first device if not specified)",
