An everyday macOS browser, with an MCP server inside it.
Fey is built on Chromium. Claude Code connects to the browser you already use, with your profile, your logins and your open tabs, and drives it. You do not need a separate integration for each service. Agent access is off until you turn it on in Settings, and Esc takes any tab back from the agent.

MCP access to the browser you already use
Your agent works in your real profile, with your logins and your open tabs. Each call acts and returns the result in one round trip. It reads back only what changed, not the whole page, so runs stay fast and use fewer tokens. It also sees your spaces, folders and pinned tabs.

Every space is its own Chromium profile
Work, personal, a client's account. Each space uses a separate profile, so cookies and sessions never cross between them. Fey loads only the space on screen, and the others cost nothing until you switch to them.
Sign-in without giving the agent your password
The agent asks Fey to sign you in. Fey asks you first and names the site, the account and the client that asked. The login runs in a tab the agent cannot attach to, script or screenshot. The agent gets back a page that is already signed in. Passwords come from Chromium's own password manager.

Your data stays on your Mac.
No Fey server ever sees the pages you open.
Nothing leaves unless you ask
Tabs, history, favorites and passwords stay in the browser on your Mac. Fey uploads none of it unless you turn on sync.
Sync is end-to-end encrypted
Turn sync on and your Mac encrypts everything before it goes to the cloud. Fey holds no key, so nobody at Fey can read your tabs. Your phone joins by scanning a QR code.
Agent access is off until you turn it on
Once it is on, the sidebar marks every tab an agent touches, and one click takes the tab back. Settings lists what agents did while you were away.
Fey does talk to its own servers for updates, five anonymous app events (installs, launches, active days) and crash reports. None of them carry a page, an address or a search.
