Is your feature request related to a problem? Please describe.

When the MCP opens the browser it provides arguments I don't want like --disable-extensions. I'd like to be able to alter the command used to run the browser.

Describe the solution you'd like

Make the browser command configurable, or allow opting out of certain flags being set.

Describe alternatives you've considered

I tried using --chromeArg with --enable-extensions but I don't think this does anything.
