I've been using the unofficial Garmin APIs as well, but instead of an MCP I wrote an app that waits until my watch syncs after I wake up and then grabs all of yesterdays data and puts it into a Notion db.

It's been working great. The Claude morning brief compares my sleep, HRV, training status, calendar, and weather and then tells me when and how hard to workout that day.
