I figured out the issue from scouting logs, but how do I change the search URL to the proper one? That URL generates a 404, which I can confirm in the browser. How do I A) find the right URL and B) ensure it's used when trying to find MCP server?

I figured it out: It was being overridden by a setting in my Github Organization. For anyone else having this issue, make sure you have the correct registry URL in your Github Org. The proper URL is
curl "https://registry.modelcontextprotocol.io/v0.1/servers?limit=100"
