+/**
+ * Example MCP server using Hono with WebStandardStreamableHTTPServerTransport
+ *
+ * This example demonstrates using the Web Standard transport directly with Hono,
+ * which works on any runtime: Node.js, Cloudflare Workers, Deno, Bun, etc.
+ *
+ * Run with: npx tsx src/examples/server/honoWebStandardStreamableHttp.ts
