 - ✅ **Zero Infrastructure**: No servers to deploy or maintain
 - ✅ **Direct API Calls**: Native performance, no proxy overhead  
 - ✅ **Automatic Conversion**: OpenAPI schemas → UTCP tools
+- ✅ **Selective Authentication**: Only protected endpoints get auth, public endpoints remain accessible
 - ✅ **Authentication Preserved**: API keys, OAuth2, Basic auth supported
 - ✅ **Multi-format Support**: JSON, YAML, OpenAPI 2.0/3.0
 - ✅ **Batch Processing**: Convert multiple APIs simultaneously
