Ability to customize the .well-known/ directory contents

Since authenticated MCP servers use OAuth, the MCP client must be able to determine the authentication provider for the server by calling the .well-known path on the server.

I wanted to know if there is a new or hidden way to customize the .well-known/ directory contents, or the Supabase team intends to support it in the near future? Because without OAuth, the ability t…
