"""
Blender MCP example for mcp_use.

This example demonstrates how to use the mcp_use library with MCPClient
to connect an LLM to Blender through MCP tools via WebSocket.
The example assumes you have installed the Blender MCP addon from:
https://github.com/ahujasid/blender-mcp

Make sure the addon is enabled in Blender preferences and the WebSocket
server is running before executing this script.

Special thanks to https://github.com/ahujasid/blender-mcp for the server.
