Fey is a fast macOS browser with its own MCP server.
One connection instead of an MCP server per service. Your agent works the sites you are already signed into, including the ones that will never ship an integration. It stays off until you turn it on, and you can take over any tab at any time. Built on Chromium.

The browser as your agent sees it
A built-in MCP server gives your agent one tool against the live browser. It acts and reads the result in the same call, over spaces, folders and pinned rows rather than a flat list of tabs.

Spaces that share nothing
Work, personal, the side project. Each space is a browser of its own, so the two accounts you keep apart never meet in a tab strip.
Passwords an agent can use, never read
Ask an agent to sign you in and Fey asks you first, naming the site and the account. Approve, and Fey fills the password in a tab the agent cannot read. The agent gets a signed-in page, not the secret.
