Is your feature request related to a problem? Please describe.
The problem is that other tools may not have access to the location that the screenshot is being saved. I want the location to be predictable and consistent so that other tools can pick up that temporary file and use them.

Describe the solution you'd like
A new argument for take_screenshot that allows you to set the path for the output

Describe alternatives you've considered
An alternative would be to be able to force call to take_screenshot to return a base64 string instead of writing a file

Additional context
This would allow other MCPs to take action on this file or allow other tools in a chain to find the screenshots and use them
