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. 20,000+ 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.
