+ *
+ * This is a thin wrapper around `WebStandardStreamableHTTPServerTransport` that provides

+ *
+ * For web-standard environments (Cloudflare Workers, Deno, Bun), use `WebStandardStreamableHTTPServerTransport` directly.

+/**
+ * Server transport for Streamable HTTP: this implements the MCP Streamable HTTP transport specification.
+ * It supports both SSE streaming and direct HTTP responses.
+ *
+ * This is a wrapper around `WebStandardStreamableHTTPServerTransport` that provides Node.js HTTP compatibility.
+ * It uses the `@hono/node-server` library to convert between Node.js HTTP and Web Standard APIs.
+ *
+ * Usage example:
+ *
+ * ```typescript
+ * // Stateful mode - server sets the session ID
+ * const statefulTransport = new StreamableHTTPServerTransport({
+ *   sessionIdGenerator: () => randomUUID(),
+ * });
+ *
+ * // Stateless mode - explicitly set session ID to undefined
+ * const statelessTransport = new StreamableHTTPServerTransport({
+ *   sessionIdGenerator: undefined,
+ * });
+ *
+ * // Using with pre-parsed request body
+ * app.post('/mcp', (req, res) => {
+ *   transport.handleRequest(req, res, req.body);
+ * });
+ * ```
+ *
+ * In stateful mode:
+ * - Session ID is generated and included in response headers
+ * - Session ID is always included in initialization responses
+ * - Requests with invalid session IDs are rejected with 404 Not Found
+ * - Non-initialization requests without a session ID are rejected with 400 Bad Request
+ * - State is maintained in-memory (connections, message history)
+ *
+ * In stateless mode:
+ * - No Session ID is included in any responses
+ * - No session validation is performed
