This is cool. I'm curious why you chose to use an extension, rather than getting the user to run Chrome with remote debugging turned on?

An extension is more user-friendly! I leave Chrome open basically 24/7 and having to create a new Chrome instance via the command line just to use Browser MCP just felt like too high of a barrier.

Of course, you're sending data to the AI model, but the "private" aspect is contrasting automating using a local browser vs. automating using a remote browser.

When you automate using a remote browser, another service (not the AI model) gets all of the browsing activity and any information you send (e.g. usernames and passwords) that's required for the automation.

With Browser MCP, since you're automating locally, your sensitive data and browser activity (apart from the results of MCP tool calls that's sent to the AI model) stay on your device.

Earlier quoted context omitted.

Not OP but I suspect it is because of this (mentioned on their page): 'Avoids bot detection and CAPTCHAs by using your real browser fingerprint.'

I don't think remote debugging by itself on a normal chrome profile is detectable

I'm sure its about the cookies/sessions but I do recall you can load cookies from another browser?

I think we need to be very careful & intentional about the language we use with these kinds of tools, especially now that the MCP floodgates have been opened. You aren't just exposing the users browsing data to which ever model they are using, you are also exposing it any tools they may be allowing as well.

A lot of non technical people are using these tools to "vibe" their way to productivity. I would explicitly tell them that potentially "all" of their browsing data is going to be exposed to their LLM client and they need to use this at their own risk.

In the Task Automation demo, how does it know all of the attributes of the motorcycle he is trying to sell? Is it relying on the underlying LLM's embedded knowledge? But then how would it know the price and mileage? Is there some underlying document not referenced in the demo? Because that information is not in the prompt.

Any plans to make a Firefox version?

Browser MCP uses the Chrome DevTools Protocol (CDP) to automate the browser so it currently only works for Chromium-based browsers.

Unfortunately, Firefox doesn't expose WebDriver BiDi (the standardized version of CDP) to browser extensions AFAIK (someone please correct me if I'm mistaken!), so I don't think I can support it even if I tried.

What I don't like about LLMs is that people keep re-inventing the wheel over and over. For example, we've been able to control browsers using GPT for about 2 years now:
