Implementation Reference
- src/tools/health.tools.ts:35-47 (registration)Registration of the 'get_steps_chart' tool with the MCP server. Defines description, input schema, and handler.
server.registerTool( 'get_steps_chart', { description: 'Get detailed intraday step data throughout the day (step chart)', inputSchema: dateParamSchema.shape, }, async ({ date }) => { const data = await client.getStepsChart(date); return { content: [{ type: 'text' as const, text: JSON.stringify(data, null, 2) }], }; }, ); - src/tools/health.tools.ts:41-46 (handler)The handler function that executes the tool logic: calls client.getStepsChart(date) and returns JSON-stringified data.
async ({ date }) => { const data = await client.getStepsChart(date); return { content: [{ type: 'text' as const, text: JSON.stringify(data, null, 2) }], }; }, - src/client/garmin.client.ts:262-265 (helper)The client method 'getStepsChart' that sends the request to the Garmin API endpoint.
async getStepsChart(date?: string): Promise<unknown> { const resolvedDate = date ?? todayString(); return this.request(`${STEPS_CHART_ENDPOINT}/${this.displayName}?date=${resolvedDate}`); } - src/dtos/date-params.dto.ts:8-12 (schema)The input schema (dateParamSchema) used by the tool: an optional date string in YYYY-MM-DD format.
export const dateParamSchema = z.object({ date: dateString .optional() .describe('Date in YYYY-MM-DD format. Defaults to today if not provided'), }); - The API endpoint constant STEPS_CHART_ENDPOINT = '/wellness-service/wellness/dailySummaryChart'.
export const STEPS_CHART_ENDPOINT = '/wellness-service/wellness/dailySummaryChart';
