>Questions

Is Shortwave MCP setup an MCP App with inline UI?

No inline MCP App UI is claimed here. It is listed as a server or host because the verified source documents MCP tools or client support, not a ui:// app resource.

Where were these details checked?

Against the maintainer's README, source, or official documentation at https://www.shortwave.com/docs/how-tos/using-mcp/, plus the GitHub API where a repository is available.
