Implementation Reference
- src/index.ts:208-232 (handler)The handler function for get_race_predictions tool. Fetches the latest 5 race predictions from Supabase 'race_predictions' table, formats times with formatTime helper, returns latest predictions for common distances and a brief history.
async function getRacePredictions() { const { data, error } = await supabase .from("race_predictions") .select("*") .order("calendar_date", { ascending: false }) .limit(5); if (error) throw error; const latest = data?.[0]; return { latest_date: latest?.calendar_date || null, predictions: { "5k": formatTime(latest?.race_time_5k), "10k": formatTime(latest?.race_time_10k), half_marathon: formatTime(latest?.race_time_half), marathon: formatTime(latest?.race_time_marathon), }, history: data?.map((r) => ({ date: r.calendar_date, "5k": formatTime(r.race_time_5k), "10k": formatTime(r.race_time_10k), })), }; } - src/index.ts:368-373 (schema)Schema definition for the get_race_predictions tool in the listTools response, including name, description, and empty input schema (no parameters required).
{ name: "get_race_predictions", description: "Get predicted race times for 5K, 10K, half marathon, and marathon based on current fitness", inputSchema: { type: "object", properties: {} }, }, - src/index.ts:417-419 (registration)Registration of the get_race_predictions tool in the CallToolRequestHandler switch statement, mapping the tool name to the handler function.
case "get_race_predictions": result = await getRacePredictions(); break; - src/index.ts:28-39 (helper)Helper function used by getRacePredictions to format seconds into readable time strings (e.g., "1:23:45").
function formatTime(seconds: number | null): string { if (!seconds) return "N/A"; const hrs = Math.floor(seconds / 3600); const mins = Math.floor((seconds % 3600) / 60); const secs = Math.round(seconds % 60); if (hrs > 0) { return `${hrs}:${mins.toString().padStart(2, "0")}:${secs .toString() .padStart(2, "0")}`; } return `${mins}:${secs.toString().padStart(2, "0")}`; }
