Magnitude interacts with the browser using Playwright. The agent exposes its BrowserContext and the Page it’s currently on via agent.context and agent.page. This can be useful when you need some lower-level browser interactions - for example manipulating cookies, listening to network traffic, or emulating specific keystrokes.

​
Example

// Inject some authorization cookies directly with browser context
await agent.context.addCookies([{ name: 'session_id', value: 'fake-session-token', domain: 'localhost', path: '/' }]);

// Mock the settings API
await agent.page.route('**/api/user/settings', async route => {
  await route.fulfill({ status: 200, contentType: 'application/json', body: JSON.stringify(mockProfileData) });
});

// Manually emulate a keypress
await agent.page.keyboard.press('ArrowRight');
If the agent switches tabs, agent.page will always refer to the agent’s active tab. See Playwright’s docs for Page and BrowserContext for details.
