Can we support in memory virtual MCP Server?

Is your feature request related to a problem? Please describe.
We want to start a mcp server in Web environment. However, due to the lack of a Node.js runtime in the browser, we are unable to launch the server directly. This limitation prevents us from simulating or interacting with the MCP server in-browser.

Describe the solution you'd like
We would like a virtual MCP server implementation that can run entirely in memory within a web environment. Ideally, this server should be lightweight, browser-compatible and capable of being initialized, paused, and resumed as needed. This would allow us to simulate server behavior without relying on a Node.js backend.

it's not documented but you can use the in memory transport in the browser.

I've also just open sourced my own in browser transports if you want to use those.
