Overview

AI-generated overview

Hosted MCP connector that lets Claude and ChatGPT read your Garmin health and fitness data through the official Garmin Health API with OAuth sign-in.

What you can do
  • Read daily wellness: steps, calories, heart rate, sleep stages and score, stress, Body Battery, HRV, with optional opt-in time series
  • List and inspect activities: runs, rides and swims with pace, distance, calories, lap splits, HR drift, pace stability, cadence and power
  • Read body composition from a smart scale and menstrual cycle snapshots, including phase and fertile window
  • Review weekly averages, directional changes and improvement trends
  • Refresh a date range of Garmin data, request recovery of a missing activity detail, and check profile, VO2max and fitness age
  • Manage subscription and account deletion, read setup and billing help, and acknowledge Garmin attribution
When to use it
Useful when you want to ask an assistant plain-language questions about your own Garmin sleep, training, body composition or cycle data without installing anything locally, and you prefer signing in on Garmin's own page over sharing your Garmin password.
Requirements
A remote Streamable HTTP endpoint added as a custom connector in Claude or found in the ChatGPT Apps Directory. OAuth 2.0 sign-in with a Garmin account is required. Cycle data needs cycle tracking enabled in Garmin Connect; body composition needs a compatible smart scale. No environment variables or headers are declared.
Before you install
Your Garmin health, activity, body composition and menstrual cycle data is sent to a third-party hosted service and synced automatically. The server can refresh data, open a billing portal, manage a paid subscription and delete the account, so confirm before letting an assistant act on those tools. A free tier exists, but the Basic plan is paid; historical data starts from the connection date unless imported from a Garmin export.

Installation

In SourceWeft

  1. Open Fitness AI Connector in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.fmp-projects%2Ffitness-ai-connector/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

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. 70,000+ users as of October 2026. Free tier available.

How it works

  1. Connect the app in ChatGPT (Apps Directory) or add the connector in Claude
  2. Sign in on Garmin's own page (OAuth 2.0 + PKCE) — we never see or store your password
  3. 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

Tools

The connector exposes 12 MCP tools:

  • get_user_profile — Garmin connection status, subscription tier, VO2max, and fitness age.
  • get_health_summary — Daily snapshot: steps, calories, heart rate, sleep stages & score, stress / Body Battery, HRV. Optional opt-in time series (heart rate, stress, Body Battery, sleep stages, SpO2, respiration).
  • get_activities — List activities (runs, rides, swims) with pace, distance, calories, and heart rate per activity.
  • get_activity_details — Lap splits, HR drift, pace stability, negative split ratio, cadence and power stats for one activity, plus optional per-second time series.
  • get_body_composition — Weight, BMI, body fat %, muscle mass, bone mass, body water % (smart scale required).
  • get_cycle_data — Menstrual cycle snapshots: phase, day in cycle, period start, cycle length (predicted vs actual), fertile window, with pregnancy semantics when applicable (cycle tracking must be enabled in Garmin Connect).
  • get_trends — Weekly averages, directional changes, and pattern detection ("am I improving?").
  • refresh_data — Re-fetch a range of Garmin data; dates before your connection date are skipped.
  • refetch_activity_detail — Request recovery of a missing activity detail.
  • manage_subscription — Billing portal and account deletion (30-day recovery).
  • get_help — Setup, troubleshooting, and billing FAQ answers.

How it compares

There are several ways to connect Garmin data to AI assistants. An honest comparison:

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.
