"openid" scope being sent when connecting to MCP server #22851
Description
Describe the problem/error/question
We are using the "MCP Client" action to connect to our MCP server. We are setting "use dynamic client registration" = true. The auth url that is generated includes a query param of "scope=openid" even though i did not set this. I also do not have a way to change this unless i set "use dynamic client registration" = false. We do not want to do that as our customers will not know all of the other pieces of info to input in that case.
What is the error message (if any)?
(from Guru's oauth screen): Authentication failed: The 'scope' parameter is invalid, the supported scope is 'default'
