browser_click
Click an element on the page using CSS selector
LABSCO SUMMARY
A script that survives the next CSS refactor.
Three of the actions — click, select and hover — exist in both a selector-addressed and a text-addressed form, which is the difference between a script that breaks the next time the styling is refactored and one that breaks only when the button's label changes. The remaining reach is browser_evaluate, which runs arbitrary JavaScript in the page: the escape hatch for anything the other nine tools cannot express, and the one to think about before you point this at a page you are logged into.
What it is
A Playwright browser server whose click, select and hover actions each come in two forms: one addressed by CSS selector, one by the element's visible text.
What you get
- Navigation to a URL, and screenshots of either the whole page or a single element, saved under a name you choose
- Clicks addressed either by CSS selector or by the text on the element
- Form filling by selector, and select-element values set by selector or by the element's text
- Hover by selector or by text, for menus and tooltips that only appear on pointer
- Arbitrary JavaScript executed in the page console
Requirements
No account and no key. The browser runs on the same machine as the server, so the pages it opens and the screenshots it writes stay there.
Setup effort
One command — npx -y @automatalabs/mcp-server-playwright
USE CASES
01
Walking a signup flow end to end
Open the page, fill the fields by selector, and press the button by the words printed on it. A screenshot at the end gives you the state the flow actually finished in.
02
Capturing evidence for a bug report
Load the page in the state that reproduces the problem and take either the full page or the one element that is wrong, so the report carries a picture rather than a description.
03
Automating a page whose markup keeps changing
Address elements by the text a user reads instead of by class names that a redesign rewrites. The label is the part of the page least likely to change silently.
04
Reading state the rendered page does not show
Run JavaScript in the page to read a variable, a computed style or the result of a function the interface never displays — the way out when no selector expresses what you need.
