"""
This is only a sample code snippet for a Gradio interface that connects to an MCP server. Server URL is set to local, it won't work on spaces.

This script initializes a Gradio interface for an agent that uses tools from the MCP server.
It connects to the MCP server, retrieves available tools, and sets up a chat interface where users can interact with the agent.
