Hi,
I'm trying to connect cursor.com web agents (not cursor local) to jira. In cursor.com you can connect to MCP servers

When I click on Login it's asking me to authorise the app, but on the second screen I get this blocking error

I am a Jira admin, but there's so many admin pages and apps that I don't know where to do this. Please could someone direct me to the right page?
Thanks
