How do I use Example 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., "@Example MCP Server show me how to add this server to Claude Desktop" 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.
