uBrowser Automation FAQs

Question 1

Does uBrowser support multiple browser tabs?

Accepted Answer

Yes, the 'browser_pages' tool allows you to create, switch, list, and close multiple browser pages within a single session.

Question 2

What are element references (refs) in uBrowser?

Accepted Answer

Refs are short IDs (like e1, e2) assigned to interactive elements in snapshots. Using these short IDs in commands instead of full CSS selectors further reduces token consumption.

Question 3

How does uBrowser achieve a 98% reduction in token costs?

Accepted Answer

uBrowser uses 'browser_batch' to execute multiple actions like navigating, typing, and clicking in a single call, returning only a final snapshot rather than sending data back for every individual step.

Question 4

Do I need to install Playwright separately?

Accepted Answer

The uBrowser server script handles dependencies and downloads the necessary Playwright Chromium binaries automatically during its first run.

Question 5

Can I use uBrowser for automated testing?

Accepted Answer

Yes, uBrowser is ideal for testing as it supports headless mode, element inspection, and complex multi-page interactions while remaining significantly cheaper than traditional MCP browser tools.
