Show HN: The Ultimate MCP Client Over the past couple weeks, l've been really immersed in learning about MCP, a new protocol for equipping any LLM with a set of tools that can run on your own machine or a remote server you control and give all kinds of superpowers to Al agents to do things like search, etc. As part of that research, l've already built one very fleshed-out and useful MCP server that l've shared here (I've added much more to it recently though!), the LLM Gateway MCP Server, which lets you use a big model to delegate to a cheaper model (and many more things in addition to that, like running automated multi-round LLM Tournaments, which I also posted about recently on X). To actually use these MCP servers though, you need an MCP client. Most people seem to be using the Claude Desktop app. I tried this and got it to work just fine, but it was a bit annoying to set up and there were lots of things I didn't like about it. I wanted something better. So two days ago I began work on what I call the Ultimate MCP Client. After ~24 hours of work, it's working and ready and I'm really proud of how amazingly well it turned out. This is going to be a workhorse tool for me personally. It's pure python and all in a single large .py file which can be deployed as a self-contained uv script if you want. It offers all kinds of features and very rich console output for use interactively in a terminal, along with a CLI. But it can also be used in the background. That kind of background functionality, orchestrating and coordinating several MCP servers nicely, is how I mostly intend on using it. But once I saw how nice the interactive terminal experience was, I realized that I could slap a FastAPl server on top of it and make a web GUl. Because I hate unneeded complexity so much, I made the WebGUl a single self-contained HTML file you can just open in your browser (similar to my Your-Source-to-Prompt tool), and it looks awesome using Alpine and Daisy and other nice Ul libraries, all loaded via CDN. https://ift.tt/4WBc3lw April 10, 2025 at 02:26AM
