NexusBrowser MCP
An open-source MCP server that allows AI agents like Claude, Codex, and Antigravity to drive the user's real Chrome browser in background tabs. It uses a local bridge and Chrome extension to provide tools for tab management, form filling, clicking, network logging, and content export while maintaining strict tab ownership and masking sensitive data like passwords.
