Ask about last night's sleep, HRV trends, Body Battery, stress, training load, weight, or a specific run, all from your real Garmin account. It runs on Garmin's official Personal API with a revocable key, so it never needs your Garmin password, and it's read-only. Published on PyPI as [`garmin-personal-mcp`](https://pypi.org/project/garmin-personal-mcp/) and in the official MCP Registry as `io.github.Mason-Levyy/garmin-personal-mcp`. <!-- mcp-name: io.github.Mason-Levyy/garmin-personal-mcp --> > **Unofficial project, official API.** This isn't made by Garmin, but it only > talks to Garmin's documented > [Personal API](https://developer.garmin.com/gc-developer-program/personal/personal-api) > through [Garmin's own Python client](https://github.com/garmin/connect-personal-api-python). ## How is this different from other Garmin MCP servers? Most Garmin MCP servers sign in with your Garmin password through the unofficial `garminconnect` library, which breaks whenever Garmin changes its login. In October 2026 Garmin opened a Personal API for individuals. This server uses it: - **No password, no scraping**: a revocable Personal API key you create in Garmin Connect, exchanged for short-lived tokens - **The whole Personal API**: every working endpoint in Garmin's reference has a tool, with every documented filter - **Any date range**: ranges longer than an endpoint allows (28 days for steps, 31 for sleep, and so on) are split into requests for you - **Model-sized responses**: all-day sample arrays are left out unless you ask for them - **Read-only**: the Personal API can't change your account, and neither can this server ## Quickstart 1. Save your Personal API key (one-time; see [Authentication](#authentication)): ```bash uvx garmin-personal-mcp auth ``` 2. Add the server to your client. The install buttons at the top do this in one click for Cursor and VS Code. **Claude Code** ```bash claude mcp add garmin -- uvx garmin-personal-mcp ``` Or install it as a plugin, which asks for your key in place of step 1: ``` /plugin install garmin-personal-mcp --marketplace Mason-Levyy/garmin-personal-mcp ``` **Claude Desktop** (`claude_desktop_config.json`), **Cursor** (`~/.cursor/mcp.json`), **Windsurf** (`~/.codeium/windsurf/mcp_config.json`), and **Cline** (`cline_mcp_settings.json`) all take the same entry: ```json { "mcpServers": { "garmin": { "command": "uvx", "args": ["garmin-personal-mcp"] } } } ``` <details> <summary><b>VS Code, Codex CLI, Gemini CLI</b></summary> VS Code (or use the button above): ```bash code --add-mcp '{"name":"garmin","command":"uvx","args":["garmin-personal-mcp"]}' ``` Codex CLI: ```bash codex mcp add garmin -- uvx garmin-personal-mcp ``` Gemini CLI: ```bash gemini mcp add garmin uvx garmin-personal-mcp ``` </details> 3. Ask it something: *"how did I sleep last night?"*, *"is my HRV trending down this month?"*, *"compare my last three long runs"*. Requires [uv](https://docs.astral.sh/uv/). Any MCP client that speaks stdio or streamable HTTP works, not just Claude. > **Finding this useful?** A ⭐ on > [GitHub](https://github.com/Mason-Levyy/garmin-personal-mcp) helps other > Garmin users find it. ## Authentication 1. Sign in to Garmin Connect on the web and open [Settings → Personal API](https://connect.garmin.com/app/settings/personalApiToken). 2. Create a key and choose how long it lasts (30 days to a year). Garmin shows it once. 3. Run `garmin-personal-mcp auth` and paste it at the hidden prompt. The server checks it with Garmin before saving it to `~/.config/garmin/connect-personal-api-key` with owner-only permissions. Where there's no terminal to prompt in (a script, or a shell an agent runs), pipe the key in instead, e.g. `pbpaste | garmin-personal-mcp auth`. `garmin-personal-mcp auth --check` reports whether the saved key still works, without prompting. Garmin emails you about a week before a key expires: create a new one and run `auth` again. No restart is needed; the server reads the key on every call. Instead of the key file you can set `GARMIN_PERSONAL_API_KEY`, which takes precedence. The key file and bearer-token cache are the same ones Garmin's `gc-personal` CLI uses, so a key saved by either works for both. ## Tools All tools take dates as `YYYY-MM-DD`. Range tools default to the 7 days ending today. Tools that return a list wrap it as `{"results": [...]}`. | Tool | What it returns | | --- | --- | | `garmin_get_day` | One day at a glance: summary, sleep, HRV, Body Battery, stress, and activities | | `garmin_get_daily_summary` | Every all-day wellness total for one date | | `garmin_get_daily_summaries` | Daily summaries across a range (trends over weeks or months) | | `garmin_get_steps` | Daily steps, distance, and goal | | `garmin_get_stress` | Daily stress level and time in each stress band | | `garmin_get_hydration` | Daily intake, goal, and sweat loss | | `garmin_get_body_battery` | Daily charge/drain and the events behind it; `chunks` for intraday lows/highs | | `garmin_get_heart_rate` | Resting/min/max HR, 7-day resting average, abnormal HR alerts; samples on request | | `garmin_get_spo2` | Pulse ox averages, hourly averages, acclimation; readings on request | | `garmin_get_wellness_activities` | Wellness activities with summary values and time in zones | | `garmin_get_sleep` | One night in full: score, stages, timings, overnight vitals | | `garmin_get_sleep_summaries` | Nightly sleep records across a range | | `garmin_get_hrv` | One night of HRV with every reading | | `garmin_get_hrv_summaries` | Nightly HRV, weekly average, baseline, and status across a range | | `garmin_get_weight` | Daily weight summaries, range average, and adjacent weigh-ins; every weigh-in with `include_all` | | `garmin_get_weight_goals` | Weight goals in effect and their target ranges | | `garmin_get_food_log` | Garmin Connect nutrition log: foods, nutrients, goals, meals | | `garmin_search_activities` | Activities with every filter Garmin supports (type, dates, distance, power, area, dives, ...) | | `garmin_get_activity` | One activity in full, with splits | | `garmin_get_activity_workouts` | The structured workout followed during an activity | | `garmin_download_activity` | Save an activity's original file (ZIP with the .fit) on the server's machine | | `garmin_get_profile` | Units, formats, time zone, and training-day preferences | | `garmin_get_heart_rate_zones` | Zone floors per sport and the HRs they're based on | | `garmin_get_fitness_age` | Fitness age, achievable fitness age, and its components | | `garmin_get_menstrual_cycle` | Cycle phase, day, fertile window, and predictions | | `garmin_get_menstrual_day` | One day's logged symptoms, flow, and cycle detail | Weights are in grams, distances in meters, and durations in seconds, as Garmin returns them. ## Remote / HTTP mode The default transport is stdio. For network clients: ```bash garmin-personal-mcp --http --host 127.0.0.1 --port 8491 ``` This serves streamable HTTP at `/mcp`. **There is no built-in authentication. Never expose it to the internet.** Bind to localhost and front it with something that authenticates for you: a VPN or tailnet (e.g. `tailscale serve`), an authenticating reverse proxy, or an OAuth-aware MCP gateway. Behind a proxy, pass `--allowed-host <proxy hostname>` (repeatable) so the DNS-rebinding check accepts its Host header. ## Configuration | Variable | Purpose | Default | | --- | --- | --- | | `GARMIN_PERSONAL_API_KEY` | Personal API key; overrides the saved key file | – | | `GARMIN_MCP_DOWNLOAD_DIR` | Where `garmin_download_activity` saves files; the tool can't write outside it | `~/Downloads/garmin` (platform downloads dir) | ## Troubleshooting - **"Garmin rejected the Personal API key"**: the key expired or was deleted. Create a new one and run `garmin-personal-mcp auth`. - **"No usable Garmin Personal API key was found"**: run `garmin-personal-mcp auth`, or set `GARMIN_PERSONAL_API_KEY` in the client config. - **`{"no_data": ...}`**: Garmin has nothing for that date yet (today's HRV before you've slept, for example), or your device doesn't record that metric. - **HTTP 400 on a long range**: an endpoint without a documented limit rejected the range. Ask for a shorter one. ## FAQ **Is this the official Garmin API?** Yes. It uses Garmin's Personal API, which anyone with a Garmin Connect account can enable without applying, through Garmin's Apache-licensed Python client. The project itself is independent. **Can it change my Garmin data?** No. The Personal API is read-only. The one tool that writes anything, `garmin_download_activity`, saves a file on your own machine. **Which MCP clients does it work with?** Any client that runs a stdio or streamable HTTP server, including Claude Desktop, Claude Code, Cursor, Windsurf, Cline, and VS Code. AI coding agents can follow [llms-install.md](https://github.com/Mason-Levyy/garmin-personal-mcp/blob/main/llms-install.md). **Where does my data go?** The server talks only to Garmin. Your key and bearer token stay in `~/.config/garmin/`. Tool results go to whichever MCP client and model you connect it to. **Can I use it for other people's accounts?** No. Garmin's Personal API is for your own data. Apps serving other users need Garmin's business developer program. ## How it works - `garmin-personal-mcp auth` saves the key; each call exchanges it for a bearer token through Garmin's `PersonalApiAuthenticator`, which caches the token until an hour before it expires. A token rejected early gets one retry with a fresh exchange. - Each tool maps to one endpoint on `personal.connectapi.garmin.com` (`garmin_get_day` combines several). Ranges longer than an endpoint's documented maximum are fetched in consecutive windows and concatenated. - Bulky per-minute sample arrays are dropped by default to keep responses readable for a model; `include_samples` or `chunks` bring them back. ## Development ```bash git clone https://github.com/Mason-Levyy/garmin-personal-mcp cd garmin-personal-mcp uv sync uv run pytest ``` Tests run against synthetic fixtures; no account needed. Lint and formatting are enforced with `ruff` (`uv run ruff check .`, `uv run ruff format .`). ## Contributing Issues and pull requests are welcome, especially when Garmin adds endpoints to the Personal API.
