Implementation Reference

• src/index.ts:160-193 (handler)

  The implementation of the get_activity_streams tool, which fetches time-series data from Strava for a given activity ID.

  server.tool(
    "get_activity_streams",
    "Get detailed time-series data (streams) for an activity: GPS coordinates, heartrate, power, cadence, altitude, etc.",
    {
      activity_id: z.number().describe("The Strava activity ID"),
      stream_types: z
        .array(
          z.enum([
            "time",
            "distance",
            "latlng",
            "altitude",
            "velocity_smooth",

    },
    async ({ activity_id, stream_types }) => {
      const keys = stream_types.join(",");
      const streams = await stravaFetch(
        `/activities/${activity_id}/streams?keys=${keys}&key_type=time`
      );
      return {
        content: [{ type: "text", text: JSON.stringify(streams, null, 2) }],
