Adding would put a customer's function app in a broken state with no clue how to fix it. The only way it would work is if customers know to include preview extension bundle. Which does not include mcp extension at the moment.

My recommendation here would be to wait until mcp extension is included in the GA bundle or is atleast part of the preview bundle and then add instructions as code comments in the .js file.
