Garmin MCP

Give your AI agent your Garmin Body Battery, training readiness, sleep, HRV and activities.
Local-first MCP server — tokens never leave your machine.

⚡ One-command install with Delx Wellness for Hermes: npx -y delx-wellness-hermes setup — preconfigures this connector and the full Delx Wellness stack in a dedicated Hermes profile.

Or wire it standalone into Claude Desktop / Cursor / ChatGPT Desktop — see the install section below. Runnable examples live in the Delx Agent Workbench.

Public proof: Garmin MCP is tracked in the Delx Open Source Growth Snapshot alongside downloads, stars and next-action priorities. If it saves you Garmin Connect and MCP setup time, star this repo so other training-focused agent builders can find it faster.

First useful prompt: Use garmin_connection_status, then garmin_daily_summary, then give me a 5-line operating brief for today.

Garmin MCP

Give your AI agent your Garmin Body Battery, training readiness, sleep, HRV and activities — local-first, tokens never leave your machine.

Unofficial project. Not affiliated with, endorsed by or supported by Garmin. This is not official Garmin Health API partnership access — it uses the unofficial Garmin Connect personal-token mode.

• Install one connector — npx -y garmin-mcp-unofficial setup
• Run it in Claude · Cursor · ChatGPT · Hermes · OpenClaw — runnable examples
• Local-first — your Garmin tokens never leave the machine (privacy)
• Which connector should I use? — pick one in the Delx Wellness front door

Part of Delx Wellness, a registry of local-first wellness MCP connectors.

Quickstart in 60 seconds

No Garmin developer app is required. setup only writes local MCP configuration; it does not ask for your Garmin password.

npx -y garmin-mcp-unofficial setup            # writes local config
npx -y garmin-mcp-unofficial auth             # built-in login, prompts for credentials locally (no Python needed)
npx -y garmin-mcp-unofficial doctor           # verifies you're ready

Or one shot: npx -y garmin-mcp-unofficial setup --auth

auth runs a self-contained Node login and prompts locally for Garmin email, password and MFA when needed. The MCP does not store your Garmin password — only Garmin Connect tokens, saved at ~/.garmin-mcp/garmin_tokens.json with user-only permissions. See the auth quickstart walkthrough for real terminal output, or docs/quickstart.md for the full flow.

If Garmin returns HTTP 429, a Cloudflare challenge, or an auth message that says Garmin SSO omitted responseStatus.type, stop retrying for a while. Repeated headless login attempts can make the private endpoint throttle harder. Use docs/auth.md for the safe recovery path.

Then add this to your MCP client config:

{
  "mcpServers": {
    "garmin": {
      "command": "npx",
      "args": ["-y", "garmin-mcp-unofficial"]
    }
  }
}

Try it with your agent

Use garmin_connection_status to check setup, then run garmin_daily_summary.
Give me a 5-line operating brief for today.

Call garmin_weekly_summary with response_format=json. Identify my biggest
recovery/sleep/stress bottleneck and give me a next-week plan.

Use the garmin_intraday_investigation prompt for date=today, focus=stress.
Don't claim Garmin can prove anything it can't.

Tools

Start with garmin_connection_status, then garmin_daily_summary (daily readiness, sleep, load) or garmin_weekly_summary (scorecard, bottlenecks, next-week plan). The server also exposes per-day signals (sleep, HRV, stress, Body Battery, training readiness, heart rate, SpO2, respiration, intensity minutes, hydration), activities, profile/devices and weight, plus prompts and resources.

See docs/tools.md for the full tool list, prompts, resources, data-availability matrix, configuration, Hermes setup and development notes.

Privacy & what runs offline

• GARMIN_PRIVACY_MODE defaults to summary (more conservative than other Delx Wellness connectors) because the auth model is unofficial.
• In structured mode, normalized aliases are additive: complete upstream Garmin fields and nested DTOs remain available after secret/GPS redaction.
• Activity date ranges preserve the supplied calendar date and reject invalid values before contacting Garmin Connect.
• Garmin Connect tokens are stored at ~/.garmin-mcp/garmin_tokens.json with user-only permissions and are never returned by tools. Your Garmin password is never stored — only short-lived tokens persist locally.
• The MCP client never sees Garmin credentials or tokens. Local cache is opt-in via GARMIN_CACHE=sqlite.
• This is not medical advice. The server exposes user-authorized data for personal AI workflows, not diagnosis or treatment.

See docs/privacy.md for the full privacy model.

Want to see a connector like this drive a real end-to-end decision? The shared, reproducible proof lives in delx-living-body:

npx -y delx-living-body demo

It answers the anchor question — "Should I train hard today?" — by combining recovery, sleep and training-load signals across the Delx Wellness connectors.
