d150772e24* feat: add MCP Apps extension (io.modelcontextprotocol/ui) support Adds support for the MCP Apps protocol extension, which lets servers expose interactive HTML UIs as resources rendered by spec-conforming clients (e.g. Goose) in sandboxed iframes. - Generic extension plumbing: ServerExtensionInterface and Builder::enableExtension(), with extensions advertised under capabilities.extensions during the initialize handshake. ClientCapabilities/ServerCapabilities gain an extensions field. - Schema DTOs under Mcp\Schema\Extension\Apps: the McpApps marker, UiToolMeta, ToolVisibility enum, UiResourceContentMeta, UiResourceCsp, and UiResourcePermissions (with empty-object presence markers per spec). - A worked weather example under examples/server/mcp-apps/ with a minimal spec-conforming view (ui/initialize handshake, postMessage JSONRPCMessage objects, and ResizeObserver-driven size reporting). - docs/extensions.md guide with pointers from index.md and examples.md to the ext-apps repository for the TypeScript SDK and richer view-side patterns. - Unit and inspector snapshot test coverage. Spec: https://github.com/modelcontextprotocol/ext-apps * Type UiToolMeta visibility as ToolVisibility enum Also fix UiResourceContentMeta::jsonSerialize() return phpdoc.
