Jan Sandbrink a4576cddcb Allow to configure MCP tool responses
This is an effort to give administrators more control
over the volume of data returned. While we don't want to limit
the actually useful part of the data, we suspect that some MCP
clients might pass both the content and the structured content
to the language model. Thus we allow admins to configure which
one will be generated.
