Agent Chrome Relay

Agent Chrome Relay: Command line tool letting coding agents use Google Chrome with real logins in background tabs.

Agent Chrome Relay allows coding agents like Claude Code, Codex, Cursor, and Paseo to use everyday Google Chrome with real user logins from the command line. It opens agent tabs inactive in collapsed tab groups and runs DevTools commands via the Chrome debugger. The system uses a local relay, a Chrome extension, and a CLI to handle connections securely with secret tokens and process checks. It handles automatic sign-ins when accounts are already logged in and records an audit trail of actions. The tool runs on macOS and requires Node.js and Google Chrome.
