+"""
+This example shows how to reject any request without a valid token passed in the Authorization header.
+
+In order to configure the auth header, the config file for the MCP server should looks like this:
+```json
+{
+  "mcpServers": {
+    "remote-example": {
+      "command": "npx",
+      "args": [
+        "mcp-remote",
+        "http://localhost:8000/mcp",
+        "--header",
+        "Authorization:${AUTH_HEADER}"
+      ]
+    },
+    "env": {
+      "AUTH_HEADER": "Bearer <your-token>"
+    }
+  }
+}
+```
