Shuttle 0.1.0

Shuttle 0.1.0, based on Chromium 154.0.8037.129. The first public release.

Shuttle is a Chromium fork built for AI agents: every agent gets its own logged-in identity and its own tab group in
your browser, and the MCP server is built in.

Highlights

• Built-in MCP server at http://127.0.0.1:9222/mcp (Streamable HTTP): agents, sessions, tabs and 24 page tools.
• Agents with a name, color and avatar, and their own persistent storage (logins survive restarts).
• Sessions are tab groups in your window. You can hand a tab to an agent or take it back. chrome://agents manages everything.
• Per-session CDP endpoints for Playwright (connectOverCDP) and agent-browser, scoped to the session's tabs.
• No remote-debugging prompt, no automation infobar, navigator.webdriver is false, and no window at startup.
• Network mode: run Shuttle on a dedicated machine and share it over your LAN or Tailscale
  (--shuttle-listen=0.0.0.0; remote clients need the access token from ShuttleAccessToken).
• Google services, sign-in, sync, telemetry, Google AI features, translate, the password manager and the side panel
  have been removed.

Known limits

• Early release. No auto-update yet, so watch this page for new releases.
• By default the CDP/MCP port is localhost only, with no authentication (web pages are rejected by Origin/Host checks).
  Network mode requires a token for remote clients; traffic is plain HTTP, so use trusted networks or Tailscale/SSH.
• Linux: on Ubuntu 23.10+ install the bundled chrome-sandbox setuid helper (see README-LINUX.txt).
• Open codecs only: H.264-only video won't play, and there's no Widevine.
• English UI only. macOS builds are arm64 only for now.
