Reimplement the MCP Apps ui-meta helpers (RESOURCE_MIME_TYPE, getToolUiResourceUri, isToolVisibilityModelOnly, isToolVisibilityAppOnly) in packages/api/src/mcp/apps.ts so @librechat/api no longer imports the ESM-only @modelcontextprotocol/ext-apps from its CommonJS build. ext-apps remains a client-only dependency, removing the require(ESM) boundary that throws ERR_REQUIRE_ESM on Node versions without synchronous require(esm) support. Add an mcpSettings.apps toggle (enabled unless explicitly false). Thread enableApps through connection creation so the io.modelcontextprotocol/ui capability is advertised only when apps are enabled, and gate the resource and app-tool-call routes with a requireMCPAppsEnabled middleware. Authorize app-driven resources/read against the resources and templates a server advertises, so a sandboxed app cannot proxy arbitrary uris. ui:// resources stay allowed and the check fails closed. Render MCP apps in shared and search transcripts display-only by withholding the host-bound bridge handlers and capabilities in read-only views, so an embedded app cannot call tools or read resources with the viewer's auth while the stored tool result still renders. |
