Interface McpUiAppCapabilities

Capabilities provided by the Guest UI (App).

Apps declare these capabilities during the initialization handshake to indicate what features they provide to the host.

const app = new App(
  { name: "MyApp", version: "1.0.0" },
  { tools: { listChanged: true } }
);

McpUiInitializeRequest for the initialization request that includes these capabilities

interface McpUiAppCapabilities {
experimental?: {};
tools?: { listChanged?: boolean };
}

Properties

experimental?: {}

Experimental features (structure TBD)

tools?: { listChanged?: boolean }

App exposes MCP-style tools that the host can call. These are app-specific tools, not proxied from the server.
