Implementation Reference
- src/server.ts:388-423 (handler)The handler function for the getFoodLogs tool. It uses formatDate to prepare the date, calls makeApiRequest to fetch food logs from the Fitbit API endpoint `/user/-/foods/log/date/{date}.json`, formats the response with meals and summary, and returns it as MCP content or an error response.async ({ date }) => { try { const formattedDate = formatDate(date); const endpoint = `/user/-/foods/log/date/${formattedDate}.json`; const data = await makeApiRequest(endpoint); return { content: [ { type: "text", text: JSON.stringify( { date: formattedDate, meals: data.foods || [], summary: data.summary || {}, }, null, 2 ), }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error: ${ error instanceof Error ? error.message : String(error) }`, }, ], isError: true, }; } }
- src/server.ts:382-387 (schema)Zod input schema for the getFoodLogs tool, defining an optional 'date' string parameter.{ date: z .string() .optional() .describe("Date in YYYY-MM-DD format. If not specified, will use today."), },
- src/server.ts:380-424 (registration)Registration of the getFoodLogs tool on the MCP server instance using server.tool(name, schema, handler).server.tool( "getFoodLogs", { date: z .string() .optional() .describe("Date in YYYY-MM-DD format. If not specified, will use today."), }, async ({ date }) => { try { const formattedDate = formatDate(date); const endpoint = `/user/-/foods/log/date/${formattedDate}.json`; const data = await makeApiRequest(endpoint); return { content: [ { type: "text", text: JSON.stringify( { date: formattedDate, meals: data.foods || [], summary: data.summary || {}, }, null, 2 ), }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error: ${ error instanceof Error ? error.message : String(error) }`, }, ], isError: true, }; } } );
- src/server.ts:44-65 (helper)Helper function makeApiRequest used by the getFoodLogs handler to perform authenticated GET requests to the Fitbit API.async function makeApiRequest(endpoint: string): Promise<any> { try { const url = `${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; } }
- src/server.ts:68-72 (helper)Helper function formatDate used by the getFoodLogs handler to normalize the date parameter or default to today.function formatDate(date?: string): string { if (date) return date; const today = new Date(); return today.toISOString().split("T")[0]; // YYYY-MM-DD }
