How do I use FeelFit 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., "@FeelFit MCP Server What's my latest weight and body fat percentage?" 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.
