**Smart Defaults:**
- `*mcpServerUrl`: If not set, automatically uses ingress host (if enabled) or `http://localhost:8000` (for port-forward setups)
- `**publicIssuerUrl`: If not set, automatically defaults to `nextcloud.host` (which works when both clients and MCP server access Nextcloud at the same URL)

#### OAuth with Existing Secret (Pre-registered Client)

```bash
kubectl create secret generic nextcloud-oauth-creds \
--from-literal=clientId=my-oauth-client-id \
--from-literal=clientSecret=my-oauth-client-secret

### Example 3: OAuth with Document Processing and Dynamic Client Registration
This example shows OAuth without pre-registered credentials (using DCR) and optional URL values:
```yaml
nextcloud:

# mcpServerUrl will automatically use ingress host (https://mcp.example.com)
# publicIssuerUrl will automatically default to nextcloud.host
auth:
