Workshop enables developers to build and run custom Model Context Protocol (MCP) servers that connect external data sources directly into their development environment. Using JavaScript and the `@modelcontextprotocol/sdk`, it implements MCP servers that can fetch live data from public APIs such as Open-Meteo and AgroMonitoring. By defining `resource()` and `tool()` interfaces accessible via MCP URIs, it allows for structured responses within tools supporting MCP, such as VS Code, enhancing developer productivity.
