+ * Node.js via `@hono/node-server`).
+ *
+ * `createMcpHandler(...).fetch` is the web-standard face: pass the raw
+ * `Request` and return the `Response`. The `@modelcontextprotocol/hono`
+ * package adds the same DNS-rebinding / origin protection middleware the
+ * Express adapter ships.
+ *
+ * HTTP-only — the point is the Hono adapter; a stdio leg would bypass it.
