The official ext-apps repository now keeps its SolidJS starter under examples/basic-server-solid. It demonstrates an MCP server, a Solid view, a ui:// resource and the postMessage bridge used by MCP Apps hosts.

Not for: A finished end-user product. It is a reference implementation for developers and still needs product-specific tools, authentication, data handling and design.

>Questions

Is SolidJS MCP App Starter an MCP App with inline UI?

Yes. The maintainer's source declares an MCP UI resource and links it to a tool result. It renders inline only in hosts that support MCP Apps.

Where were these details checked?

Against the maintainer's README, source, or official documentation at https://github.com/modelcontextprotocol/ext-apps/tree/main/examples/basic-server-solid, plus the GitHub API where a repository is available.
