What steps can reproduce the bug?
Try to authenticate the remote MCP server using an Entra Client
What is the expected behavior?
The user should be able to pass a scope in config.toml. For example, [mcp_servers.x] could receive an oauth_scopes that is a vector of strings that should be requested in the token. I tested this approach locally and it works.
