Browser Control MCP server

Lets your AI manage your Firefox tabs, search your history, and read webpages you approve.

This is a helper that connects your AI assistant to your own Firefox browser. It comes in two parts: a small Firefox add-on and a matching helper program for your AI. It is handy if you want your AI to tidy up your tabs, dig through your browsing history, or read a page for you without you copying and pasting anything.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. It cannot see your browser or click anything there. An MCP server is a small helper program that gives your AI a new skill. This one gives your AI a connection to your Firefox browser, so when you ask it to open a tab or look something up in your history, it can actually do it.

What this MCP server does

You ask your AI something about your browser, like closing tabs or finding an old article. Your AI passes that request to this helper program. The helper talks to the Firefox add-on sitting in your browser. The add-on does the actual work, like closing a tab or reading a page you allowed. Then the result comes back to your AI, and your AI tells you what happened.

Flow diagram: you ask your AI “Close all my non-work tabs”, on your own computer the Browser Control MCP server works with your Firefox browser, and you get back answers right in your chat.

Try asking your AI

“Close all non-work-related tabs in my browser.”
“Group all development related tabs into a new group called Development.”
“Help me find an article in my browser history about the Milford track in NZ.”
“Open hackernews in my browser, then open the top story, read it, and also read the comments. Do the comments agree with the story?”

What it gives back to you

You get answers and lists right in your chat. For example, a list of your open tabs, matching articles from your history, or a summary of a page your AI just read. If it changed something, like closing or grouping tabs, it tells you what it did. Screenshots come back as an image of the tab's visible area.
