Implementation Reference

• src/adb.ts:312-315 (handler)

  The actual implementation of the type_text logic using `input text` via adb.

  async typeText(text: string, deviceId?: string): Promise<void> {
    const escaped = escapeShellText(text);
    await this.exec(["shell", "input", "text", escaped], deviceId);
  }

• src/index.ts:291-302 (registration)

  MCP tool registration for "type_text" and the handler wrapper.

  server.tool(
    "type_text",
    "Type text into the currently focused input field",
    {
      text: z.string().describe("Text to type"),
      device_id: z.string().optional().describe("Device ID (optional if only one device)"),
    },
    async ({ text, device_id }) => {
      await adb.typeText(text, device_id);
      return { content: [{ type: "text", text: `Typed: "${text}"` }] };
    },
  );
