Implementation Reference

• src/tools/keyboard.ts:33-49 (handler)

  The handler function for the browser_press_key tool. It presses the specified key on the current tab's page using Playwright's keyboard.press method, generates corresponding code snippet, and returns an action object.

  handle: async (context, params) => {
    const tab = context.currentTabOrDie();
  
    const code = [
      `// Press ${params.key}`,
      `await page.keyboard.press('${params.key}');`,
    ];
  
    const action = () => tab.page.keyboard.press(params.key);
  
    return {
      code,
      action,
      captureSnapshot,
      waitForNetwork: true
    };
  },

• src/tools/keyboard.ts:23-31 (schema)

  Schema definition for the browser_press_key tool, including name, title, description, input schema with 'key' parameter validated by Zod, and type 'destructive'.

  schema: {
    name: 'browser_press_key',
    title: 'Press a key',
    description: 'Press a key on the keyboard',
    inputSchema: z.object({
      key: z.string().describe('Name of the key to press or a character to generate, such as `ArrowLeft` or `a`'),
    }),
    type: 'destructive',
  },

• src/tools/keyboard.ts:52-54 (registration)

  Exports and registers the browser_press_key tool by including it in the array returned from the tool factory with captureSnapshot parameter.

  export default (captureSnapshot: boolean) => [
    pressKey(captureSnapshot),
  ];
