+      (MCP) client that communicates with the Brave Search MCP Server. The
+      application shows how to build an MCP client that enables natural language
+      interactions with Brave Search, allowing you to perform internet searches
+      through a conversational interface. This example uses the official Go SDK
+      for Model Context Protocol servers and clients, to set up the MCP client.
