Garmin Connect Personal API

Garmin Connect Personal API MCP

Not affiliated with or endorsed by Garmin. Garmin and Garmin Connect are trademarks of Garmin Ltd.

A read-only MCP server that gives AI assistants your own Garmin Connect training, recovery and health data through the official Garmin Connect Personal API. Run it on your own computer, or host it on your own Cloudflare account to use it from anywhere.

AI agents: to set this up for a user, follow docs/AGENT-SETUP.md.

Setup

You need a Garmin Connect Personal API key, which you create in Garmin Connect on the web.

Run locally

The quickest way, for Claude Code, Claude Desktop, Cursor, VS Code and other clients that run local servers. Needs Node.js 22+.

Paste this into your coding agent:

Connect @hannta/garmin-connect-personal-api-mcp

Or do it yourself: docs/LOCAL.md.

Host on Cloudflare

For Claude on the web and on mobile, and any other client that connects to remote servers with OAuth. The free plan is enough, apart from one known limitation.

• One click:

  

• Manual: follow docs/DEPLOY.md.

Then connect your MCP client, such as Claude, ChatGPT, Cursor or VS Code.

Good to know

• Range tools default to the last 7 days. If a range is too long for one Garmin request, the error says the maximum and the assistant splits it into several calls.
• Output is metric, with the unit in every field name. Dates are YYYY-MM-DD in your time zone; sleep and HRV are keyed by the wake-up date.
• Location, sexual activity and sex drive data are never returned.
• Known limitation: garmin_get_activity_laps can fail on long activities on the Cloudflare free plan. See Known limitations.

Development

Requires Node.js 24+.

npm install
cp .dev.vars.example .dev.vars   # then add GARMIN_API_KEY and OWNER_PASSPHRASE
npm run check                     # typecheck, lint, format check, tests
npm run today                     # print today's recovery data using your key
npm run dev                       # MCP server at http://localhost:8787/mcp
npm run build                     # local server in dist/cli.mjs

To try the local server, connect the MCP Inspector to it and sign in with OWNER_PASSPHRASE.
