Your apps have moved into Claude

Interactive connectors let a partner's app appear inside Claude, Anthropic's assistant, and this update lets the whole app open there. Until now, according to Anthropic's detailed announcement, these connectors showed a small live view of a tool inside the conversation. Where a connector supports it, the full tool can now open beside the chat or full screen, signed into the user's own account, so Confluence or Notion opens as its complete editor rather than a preview. The user can work in the tool directly or ask Claude to make changes, approving Claude's actions the same way as other connector actions, and the edits appear in the tool as Claude makes them. The video's description says it shows Claude adding a summary to a launch plan in Confluence, applying a dither effect to a photo in Adobe, and checking a floor plan in Box against a design standard before saving the revision as a new file.

Underneath is MCP Apps, an open extension to the Model Context Protocol that lets a tool's server supply its own interface to an AI application. An earlier talk explains how the host renders that interface in a sandbox and passes the user's actions back. Claude previously showed MCP Apps mainly as views inside the conversation; it now supports more of the extension, including app tools and embedded sites, so a developer's full app can run inside Claude. That developer support is in public preview, and Anthropic says an app built this way can run in any AI application that supports the extension. The rollout covers the web and desktop apps on all plans, as part of the new Claude experience that combines chat and Cowork, and reaches people once their account or organization has moved to it. Admins can restrict a connector's tools as they do today.
