# AUTH_PROVIDER_AVAILABLE

**What it means.** This app implements its own login, but the platform already signs people in.

**What to do.** Remove the auth library and read the signed-in user with getUser(request) from @uarpie/sdk. Invited people are signed in by the platform before the app runs. This is a warning; deploy continues.

- HTTP status: 422
- Retryable after applying the fix: yes

Every failure from the CLI or an MCP tool has this shape:

```json
{
  "ok": false,
  "code": "AUTH_PROVIDER_AVAILABLE",
  "message": "This app implements its own login, but the platform already signs people in.",
  "fix": "Remove the auth library and read the signed-in user with getUser(request) from @uarpie/sdk. Invited people are signed in by the platform before the app runs. This is a warning; deploy continues.",
  "file": "<where to edit, when known>",
  "retryable": true,
  "docs": "https://docs.uarpie.app/errors/AUTH_PROVIDER_AVAILABLE"
}
```

Apply `fix` (edit `file` when it is given), then run the same command again.
