Implementation Reference
- src/services/noaa-service.ts:114-120 (handler)Core handler function that fetches meteorological data from NOAA API by calling fetchDataApi with the provided parameters including the product type.
async getMeteorologicalData(params: Record<string, any>): Promise<any> { const { product, ...rest } = params; return this.fetchDataApi({ ...rest, product }); } - src/interfaces/noaa.ts:84-97 (schema)Zod schema defining input parameters for the get_meteorological_data tool, including station, product, date parameters, with validation refinement.
export const GetMeteorologicalDataSchema = z.object({ station: StationSchema, product: z.string().min(1).describe('Product (air_temperature, wind, etc.)'), date: DateSchema, begin_date: BeginDateSchema, end_date: EndDateSchema, range: RangeSchema, units: UnitsSchema, time_zone: TimeZoneSchema, format: FormatSchema, }).refine( data => (data.date || (data.begin_date && data.end_date) || (data.begin_date && data.range) || (data.end_date && data.range) || data.range), { message: "You must provide either 'date', 'begin_date' and 'end_date', 'begin_date' and 'range', 'end_date' and 'range', or just 'range'" } ); - src/server/mcp-server.ts:74-81 (registration)Tool registration in McpServer class: defines the MCPTool object with name, description, schema, and handler delegating to NoaaService.
const getMeteorologicalData: MCPTool = { name: "get_meteorological_data", description: "Get meteorological data", inputSchema: GetMeteorologicalDataSchema, handler: async (params) => { return this.noaaService.getMeteorologicalData(params); } }; - src/tools/water-tools.ts:140-165 (registration)Alternative tool registration using FastMCP server.addTool, with inline Zod parameters schema and execute handler calling NoaaService.
