apps

MCP Apps: a tool result carries a _meta.ui reference to a ui:// resource that the host renders as an interactive surface. The story will register a @ui resource and return it from a tool.

Status: not yet implemented (#2896). The extensions capability map is not yet surfaced on MCPServer, so a server cannot advertise Apps support and a client cannot negotiate it.

Spec

MCP Apps — extensions · SEP-2133 — extensions capability
