Fitness AI Connector
Talk to your Garmin data in Claude and ChatGPT.
Connect your Garmin health and fitness data to Claude and ChatGPT through the official Garmin Health API. Hosted remote MCP server (Streamable HTTP) with OAuth 2.0 sign-in — your Garmin password is never shared. 12 tools: daily health summary (sleep, HRV, stress, Body Battery), activities with lap and time-series analysis, body composition, menstrual cycle tracking, trends, and on-demand data refresh. 15,000+ users as of September 2026. Free tier available.

How it works
- Connect the app in ChatGPT (Apps Directory) or add the connector in Claude
- Sign in on Garmin's own page (OAuth 2.0 + PKCE) — we never see or store your password
- Ask questions in plain language: "How did I sleep this week?", "Show the details of my latest run", "Am I improving?"
Your Garmin data syncs automatically via the Garmin Health API webhook/pull model. You can disconnect from your Garmin account settings or delete all data at any time.
What you can ask
| Area | Examples |
|---|---|
| Daily wellness | Steps, calories, heart rate, sleep stages & score, stress, Body Battery, HRV |
| Activities | Runs, rides, swims with pace, distance, calories, heart rate per activity |
| Activity details | Lap splits, HR drift, pace stability, negative splits, cadence & power stats |
| Body composition | Weight, BMI, body fat %, muscle mass (smart scale required) |
| Menstrual cycle | Cycle phase, day in cycle, fertile window, period tracking (opt-in in Garmin Connect) |
| Long-term trends | Weekly averages, directional changes, "am I improving?" comparisons |
| Profile & account | Connection status, VO2max, fitness age, subscription management |

How it compares
There are several ways to connect Garmin data to AI assistants. An honest comparison:
| Fitness AI Connector | Self-hosted OSS (e.g. garmin_mcp) | Hosted credential-based connectors | |
|---|---|---|---|
| Garmin access | Garmin Health API (official developer program) | Unofficial (reverse-engineered) API | Unofficial (reverse-engineered) API |
| Authentication | OAuth on Garmin's page; no password shared | Your Garmin email + password | Your Garmin email + password stored by operator |
| Setup | None (hosted) | Local install (Python/Node) | None (hosted) |
| Works on mobile / web chat | Yes | Desktop only (local process) | Yes |
| Historical data | From connection date onward (Garmin API policy) | Full history | Full history |
| Tool count | 12 focused tools | Up to 110+ tools | Varies |
| Price | Free tier; Basic $3/month | Free (self-managed) | Free |
| Continuity risk | Contract-backed API | Breaks when Garmin changes internal auth | Breaks when Garmin changes internal auth |
Self-hosted OSS is a great choice for developers who want maximum tool coverage and full local control. Fitness AI Connector is built for people who want a no-setup, no-password-sharing option that works in the ChatGPT and Claude apps, backed by the Garmin Health API.
