Unclear The finding does not name the address prefix or say what Claude Code does with a resource once it is recognised as an app.

What

MCP (Model Context Protocol) is the standard Claude Code uses to connect to outside servers that provide tools and resources. A new check decides whether a resource from such a server is an app's user interface. A resource counts as one when either:

  • its address starts with a particular prefix, or
  • its type is text/html with a profile parameter equal to mcp-app.

The type's parameters are now read properly, including values written in quotes.

Why

MCP servers that mark their HTML pages with profile=mcp-app are identified as app interfaces even when the address does not use the special prefix.
