/**
|
|
* Hosting on Hono / web-standard runtimes (Cloudflare Workers, Deno, Bun,
|
|
* 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.
