Dedicated Chrome Browser

A dedicated headed Chrome instance with CDP for Playwright MCP. Persistent profile (cookies/logins survive restarts), launchd-managed, multi-session safe.

Why

• Chrome's single-instance lock prevents CDP when the default profile is in use — dedicated user-data-dir required
• Headed so the user can log into sites manually; Playwright shares the session
• launchd auto-starts on login, restarts on crash
