Support web with wasm

[tlvenn]

It would be awesome if we could develop / expose mcp server / tools through web apps. I believe the current WASM state allows for this already.

Found a poc in Typescript:

For clients this will be a little bit trickier, we do want nice out of the box support for running stdio servers by spawning a process, and that requires a dart:io import currently. We could move that support to an extension and require an extra import or something, or possibly use conditional imports and just provide a throwing implementation on the browser for that method.

For servers this might already work although I haven't tested it. You will have to set up your own communication channel with the client, but its just a StreamChannel so it should be fairly easy to do whatever you want there.

I'm a little confused. I'm trying to configure and use the dart MCP server from cursor. Is that supported on Flutter stable? It worked just fine last week when I tried it.
