MCP.Pizza Chef: aeonfun

This tool lets an AI assistant drive your everyday web browser — Chrome, Firefox, Arc, or any Chromium-based browser — using the accounts, saved passwords, and cookies you already have signed in. It can post to Twitter, LinkedIn, or Facebook, read your bookmarks and browsing history, fill out and test web forms, and apply visual themes to pages you're viewing. It connects to Claude Desktop, Claude Code, Cursor, and ChatGPT, and everything runs on your own computer so your browsing data stays private.

opendia FAQ

Can I use this to post on social media for me?
Yes — it can draft and publish posts to Twitter/X, LinkedIn, or Facebook using the accounts you're already signed into in your browser.
Can I use this to test a website I'm building?
Yes — it can click through pages, fill in test data on forms, and take screenshots at each step, which is handy while you're building or checking a site.
Which apps does this work with?
It works with Claude Desktop, Claude Code, Cursor, and ChatGPT, and it's expected to work with other AI assistants that connect to Model Context Protocol tools, such as Windsurf and Gemini-based tools.
Do I need to create an account or get an API key?
No separate account is required to install the browser extension itself — you connect it to whichever AI assistant app you already use.
How hard is it to set up?
You install a browser extension and paste a short snippet into your AI assistant's settings, which takes a few minutes and doesn't require any coding.
Will it see my passwords or private browsing data?
Everything runs locally on your own computer, so your browsing data, passwords, and cookies stay on your machine and are only used when you ask your assistant to act on a page.
Can it use my saved logins and cookies instead of asking me to sign in again?
Yes — that's the main idea behind it, since it reuses your existing logged-in sessions rather than starting from scratch.
Does it work in Firefox as well as Chrome?
Yes — it supports Chrome, Firefox, Arc, Edge, Brave, Opera, and any other Chromium-based browser.
