MCP OAuth Failing with status 500 error.

[gaelph]

Hi !

We are experiencing OAuth discovery/registration issues with the Alter client (from https://alterhq.com)

The client initiates the authentication process, but when going through the registration process, the request fails with a 500 status code and no other information.

The request being sent is:

POST https://api.supermemory.ai/api/auth/mcp/register
Content-Type: application/json

{
  "redirect_uris": [
    "alter:\/\/oauth\/mcp\/callback"
  ],
  "token_endpoint_auth_method": "none",
  "scope": "openid profile email offline_access",
  "grant_types": ["authorization_code","refresh_token"],
  "response_types": ["code"],
  "client_name":"Alter"
}
