- Bots and workspaces get tools and MCP servers from their settings pages; bots also from chips under the chat composer, removable there - "Every bot" now gives one to every bot now and every new bot; each can still drop it (attach-every-bot-extensions.ts moves old installs over) - Status lines: MCP servers record whether they connect, tools whether their last run worked - Test connection in the MCP form and a Test panel in the tool form check the form as it is, without saving - Hide Google sign-in on the login form Co-Authored-By: Claude Opus 5.5 <[email protected]>
