- src/server.ts:104-109 (schema)Input schema defining optional 'date' parameter using Zod for validation.{ date: z .string() .optional() .describe("Date in YYYY-MM-DD format. If not specified, will use today."), },
- src/server.ts:102-147 (registration)Registration of the 'getActivities' tool on the MCP server, including schema and handler.server.tool( "getActivities", { date: z .string() .optional() .describe("Date in YYYY-MM-DD format.

- src/server.ts:44-64 (helper)Helper function to make authenticated HTTP requests to the Fitbit API and handle responses/errors.async function makeApiRequest(endpoint: string): Promise<any> { try { const url = `${baseUrl}${endpoint}`; const response = await fetch(url, { headers: { Authorization: `Bearer ${accessToken}`, Accept: "application/json", }, }); if (!response.ok) { throw new Error( `Fitbit API error: ${response.status} ${response.statusText}` ); } return await response.json(); } catch (error) { console.error(`Error making request to ${endpoint}:`, error); throw error; }
