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.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding does not name the address prefix or say what Claude Code does with a resource once it is recognised as an app.
