+### MCP Logging
+
+The SDK provides comprehensive logging capabilities following the [MCP logging specification](https://modelcontextprotocol.io/specification/2025-06-18/server/utilities/logging):
+
+- **Auto-injection**: `McpLogger` automatically injected into capability handlers
+- **Client-controlled filtering**: Clients can set log levels to control verbosity  
+- **Centralized logging**: All server logs flow to client for unified debugging
+- **Fallback support**: Compatible with existing PSR-3 loggers
+
+**Quick example:**
+```php
+#[McpTool(name: 'my_tool')]
+public function myTool(string $input, McpLogger $logger): array {
+    $logger->info('Tool called', ['input' => $input]);
+    return ['result' => 'processed'];
+}
+
+// Enable in server
+$server = Server::builder()
+    ->enableMcpLogging()  // Enable centralized logging
+    ->build();
+```
