Why it matters
Hosts and directories look on your domain first. A server nobody can find from your site only gets found by people who already know it.
How to pass
Publish a discovery entry under /.well-known that points to your MCP server and its server card.
Run it
Find mcp-well-known-discovery in the report. Add --md for a fix prompt you can paste into Claude Code, Codex or Cursor.
