MCP Plugin not working with MCP Inspector

Hello
When running the official https://github.com/modelcontextprotocol/inspector for authentication, it is sending an OPTIONS request to the oauth registration endpoint (http://localhost:5173/api/auth/mcp/register), which is not defined by the plugin and returns a 404.
On the inspector, this ends the signin flow and it's not possible to use the inspector

I also noticed that the plugin is not defining a .well-known/oauth-protected-resource route, which the MCP clients are querying

I am using SvelteKit
