Split server startup logic into two functions in each `server-utils.ts`:
- `startStdioServer(createServer)` - handles stdio transport
- `startHttpServer(createServer)` - handles HTTP transport
And keep the transport selection visible in each `server.ts`:
```typescript
process.argv.includes("--stdio")
? await startStdioServer(createServer)
: await startHttpServer(createServer);
```

There was a problem hiding this comment.
This introduces process.env again in server-utils, I don't like this direction tbh
And the startStdioServer method is a lot of lines to replace a one-liner.

The PORT env variable is very widely used, so reading from wherever in the code base is pretty typical for web servers.
And the startStdioServer method is a lot of lines to replace a one-liner.
The intent is instant clarity. Compare:
if(process.argv.includes("--stdio")){awaitcreateServer().connect(newStdioServerTransport());}else{constport=parseInt(process.env.PORT??"3001",10);awaitstartServer(createServer,{ port,name: "Basic MCP App Server (Preact)"});}vs
process.argv.includes("--stdio")
? awaitstartStdioServer(createServer)
: awaitstartHttpServer(createServer);Contributor
