A live-coding demo of building Model Context Protocol (MCP) tools using an agentic workflow to rapidly integrate the APIs your agents consume. We'll show how hot-reloading eliminates restart cycles that help you rapidly iterate on important annotations, like tool descriptions or arguments, or adding new API endpoints to be used in those tools.The entire stack is designed for iteration speed—change code, see results instantly, no deployment step. We'll cover the technical setup and show multiple iteration cycles in 15 minutes. Free to run, no account required
