KebabHandler implements rmcp::ServerHandler::get_info — returns
serverInfo (name="kebab", version from CARGO_PKG_VERSION) and
capabilities.tools. KebabAppState wraps Config in Arc for cheap clone
into per-request task scope. serve_stdio entry builds a multi-thread
tokio runtime and runs the server until client closes the stream.
rmcp 1.6 API used:
- rmcp::ServerHandler trait (re-exported from handler::server)
- ServerInfo::new(caps).with_server_info(impl) builder (not struct-init:
InitializeResult/Implementation are #[non_exhaustive])
- ServerCapabilities::builder().enable_tools().build() — builder macro
generated, confirms the plan-literal pattern works
- Implementation::new(name, version) — non-exhaustive constructor
- rmcp::transport::stdio() returns (tokio::io::Stdin, tokio::io::Stdout)
tuple; tuple impls IntoTransport via AsyncRead+AsyncWrite blanket
- handler.serve(transport).await → RunningService<RoleServer, H>
(ServiceExt::serve, returns Result<_, ServerInitializeError>)
- service.waiting().await → Result<QuitReason, JoinError>
- serve_stdio is plain fn wrapping a manually-built tokio runtime
(avoids nested-runtime hazard if kebab-cli ever gains its own rt)
Tools wire-up lands in subsequent tasks (one tool per task).
