Ascended Browser is a small helper that gives your AI its own web browser. You ask your AI to check a page or walk through a sign-up form, and it actually does it in a real browser window behind the scenes. It is handy for anyone testing a website or wanting the AI to look something up online.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to a real web browser, so it can open pages, read what is on them, and click or type for you when you ask.

What this MCP server does

You tell your AI what to do, for example check the login page of your app. The AI uses this helper to open a real browser and load the page. The helper reads the page and lists every button, field and link it finds. The AI then clicks, types or fills a whole form in one go, and the helper reports back what changed on the page. You get a plain summary of what happened, plus screenshots and error logs if you asked for them.

What you can do with it

Open a web page and list every button, link and form field on it
Fill in a whole form in one step, including custom dropdowns and date pickers
Read the browser console and failed network requests to spot errors
Take screenshots and compare them before and after a change
Resize the page to phone, tablet or desktop size to check the layout
Sign in with a saved login without the AI ever seeing your password
Record a task once and replay it on another page with new values

Try asking your AI

“Open my local app at localhost:3000, go through the sign-up form, and tell me if any errors appear in the console.”
“Check the checkout page on my site at phone width and take a screenshot before and after I fix the layout.”
“Go to example.com, find the pricing section, and list every plan and its price.”
“Sign in to my staging site with my saved login and take a screenshot of the dashboard.”

What it gives back to you

You get back a written summary of what the AI saw and did, such as a list of buttons and fields, the text of a page, or a note saying a click worked and what changed. Screenshots come back as pictures in the chat. Console errors and failed network requests are listed in plain text. If a page is very long, the result is shortened and the AI can ask for more.

Before you start

What you need

Python 3.11 or newer, or Node.js if you use the npm version
The uv tool (or pipx) to run the Python package
About 700 MB of free disk space for the browser download
An MCP client such as Claude Code or Codex

Good to know

The AI can click and type on real websites, so check what it is doing on important pages, and note that saved logins are stored in a file that other tools on your computer could read.

Install it with your AI
