THEN Replace the stateful SSE transport with Streamable HTTP, which supports stateless operation. Use the 'without session management' mode to avoid relying on in-memory session storage. For existing deployments, refactor to use Streamable HTTP and ensure session IDs are managed externally (e.g., via database) if needed.

// Example: using Streamable HTTP transport without session management
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StreamableHTTPServerTransport } from "@modelcontextprotocol/sdk/server/streamableHttp.js";

const transport = new StreamableHTTPServerTransport();
const server = new McpServer({ name: "example", version: "1.0.0" });
await server.connect(transport);
