How do I use Lighthouse Explorer MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Lighthouse Explorer MCP Server Show me the current network statistics and CC price in USD." That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.
