Add hosting-like way to start application #31
Description
Is your feature request related to a problem? Please describe.
I want to start and run an MCP server as part of a larger integrated application.
So I don't want it to block the main process and be the primary/singular entry-point.
Describe the solution you'd like
A hosting-like way to start the MCP server without blocking the main thread.
Describe alternatives you've considered
Subsuming the logic inside my own application, which I don't love.
Additional context
I have working code on my machine, and I'll open a PR.
