Claude supports more of the MCP Apps extension, including app tools and embedded sites

Anthropic's ClaudeDevs account says Claude now supports more of the MCP Apps extension, such as app tools and embedded sites, so a developer's full app can run inside Claude. The post links to documentation for getting started.

Anthropic's launch post for interactive connectors says the support is in public preview for developers. Until now, MCP Apps in Claude mostly appeared as interactive views inside the conversation. Now, where a connector supports it, a tool can open beside the conversation or full screen, and Claude can make changes in the page, row or file the user has open, with the user approving its actions as with any connector action. Users can also open a connected tool directly and pin tools to the sidebar. It is rolling out on the web and in the desktop app on all plans, as part of the new Claude experience, and admins can restrict a connector's tools as they do today.

Anthropic starts with a small group of directory tools, including Asana, Canva, Carta, Dropbox, monday.com, Smartsheet, Vercel and Webflow, and names Adobe, Atlassian, Box, HubSpot and Notion among the tools available. It says Figma, Harvey and Shopify are building integrations. An MCP App is not limited to Claude and can run in any application that supports the extension.
