Your AI, haunting your browser.
Yurei gives any AI coding tool a real browser. Works with every major agent and anything else that speaks MCP.
Two steps
Summon it.
-
Add Yurei to Chrome.
One click in the Chrome Web Store. Nothing to configure in the extension.
-
Run this in a terminal.
It connects to the extension, finds your AI tools and asks which ones to connect.
npx yurei-chrome setup
Restart your AI tool. That's it, the ghost is in. Needs Node.js 18 or newer. Takes about a minute. Run it again any time to add another tool.
Then
Just ask.
Talk to your AI like you always do. When a task needs a browser, it reaches for Yurei.
Open my news tab and summarise the five biggest stories.
In my inbox, find the unread message from the bank and tell me the amount.
Log in to staging as the test user and check the checkout page.
Say “in my browser” when you want to be explicit.
Compatible
Any tool. Any model.
- opencode
- pi
- Cursor
- Windsurf
- Codex CLI
- any MCP client
Models that see images take screenshots when they need them. Text-only models read the page as text.
How it works
A ghost has no body.
No server.
Your AI tool talks to the extension over a local socket, using Chrome's own debugging protocol.
No account, no open port.
Nothing leaves your computer except what your AI tool already sends to its model.
No secrets.
