Garmin MCP App

What it does

Garmin MCP App bridges your Garmin Connect account directly to Claude Desktop. Ask Claude anything about your fitness data — daily steps, sleep, heart rate, workouts, training load — and it renders interactive charts right inside the conversation. The app authenticates you via a secure in-chat login form, then reads your Garmin Connect data on demand.

Key features

• Interactive health charts — visualise steps, heart rate zones, sleep stages, stress, body battery, and HRV in real-time charts
• Workout analysis — view activity details, per-km/mile pace splits, and HR time-in-zones
• Training insights — training readiness scores, VO2 Max trends, race predictions, and training load breakdown
• Workout management — create, update, delete, and schedule structured workouts on your Garmin calendar
• Privacy-first design — credentials never leave your machine; OAuth tokens stored locally at ~/.garminconnect/ with 0600 permissions; Claude LLM never sees your email or password
