This Java-based tool demonstrates a Model Context Protocol (MCP) server implementation, specifically focusing on a weather service. It integrates with a fast-agent, leveraging the Model Context Protocol to determine which tools to call based on user prompts. The demo showcases how an agent can use Claude Sonnet 3.7, fetch lat/long data via web search and then utilize this weather service via HTTP SSE to summarize forecasts and determine the warmest city. It avoids heavy reliance on Spring, offering a lightweight solution for developers interested in MCP implementations.
