Hi — connecting Remember The Milk MCP from Grok Bot with:
https://www.rememberthemilk.com/mcp

Problem: The connector shows needs authentication, but no auth card appears. Sign-in never starts; the error is:
Redirect URIs must use HTTPS (except loopback addresses)

Tried: Exact URL above; removed and re-added the MCP server once — same error. Endpoint is reachable (auth-required responses). Notion and Google Calendar MCP in the same app work fine.

Is this a known redirect-URI issue for some MCP hosts, or is there a required setup for Grok Bot / Cursor-style clients?

Thanks.
