Implementation Reference
- src/index.js:389-454 (handler)The primary handler function for the 'get_uv_forecast' tool. It fetches UV forecast data from the IPMA API, resolves location names, groups data by date, limits to recent dates and locations, categorizes UV levels (Baixo, Moderado, Alto, Muito Alto, Extremo), formats a markdown report, and returns it as MCP text content. Handles errors with McpError.

inputSchema: { type: "object", properties: {} } - src/index.js:90-97 (registration)Registration of the 'get_uv_forecast' tool in the ListToolsRequestSchema response, including name, description, and input schema.
{ name: "get_uv_forecast", description: "Obter previsão do índice UV", inputSchema: { type: "object", properties: {} } } - src/index.js:118-119 (registration)Dispatch registration in the CallToolRequestSchema handler's switch statement, mapping the tool name to the getUVForecast method call.
