+## Configuration
+
+You can configure Cyclops MCP server via env variables. Below is an example of adding the configuration for specifying the kubeconfig file the Cyclops MCP server should use when managing your Cyclops applications.
+
+```json
+{
+  "mcpServers": {
+    "mcp-cyclops": {
+      "command": "mcp-cyclops",
+      "env": {
+        "KUBECONFIG": "/path/to/your/kubeconfig"
+      }
+    }
+  }
+}
+
+```
