What It Does

This plugin connects DeepSeek Harness to Garmin Connect, exposing your wearable data as AI-callable tools. Once installed, the DeepSeek agent can automatically query your activities, sleep, steps, and heart rate to provide personalized fitness insights — all through natural language.

Registered Tools

Tool	Description	Example Args
`get_garmin_activities`	Fetch recent activities (runs, rides, swims…) with pace, HR, calories
`get_garmin_sleep`	Sleep score, duration, and stage breakdown (deep / light / REM)
`get_garmin_steps`	Daily step count, goal progress, and walking distance
`get_garmin_heart_rate`	Resting, max, and min heart rate for a given day	`{"startDate": "2023-10-01", "endDate": "2023-10-02"}`
`get_garmin_weight`	Body composition (weight, BMI, body fat %, muscle mass, etc.)	`{"startDate": "2023-10-01"}`
`get_garmin_workouts`	Planned workouts from your Garmin calendar	`{"limit": 10, "offset": 0}`
`get_garmin_profile`	User profile summary	`null`
`export_garmin_session`	Export a session token for password-free future logins	`null`
`get_running_skill_advice`	Expert running coaching: 8 core training skills with HR zones, practice methods & common mistakes	`{"query": "threshold", "includeRecentActivities": true}`
`create_garmin_workout`	Create a structured workout (warmup/interval/repeat/cooldown with pace & HR targets) that syncs to the watch	`{"name": "Threshold 3×8min", "steps": [...]}`

Quick Start

1. Install this plugin — from the npm registry (recommended)

npx --legacy-peer-deps=false @deepseek-ai/dsh plugin --profile web add dsh-plugin-garmin-connect

This single command installs the dependency and activates the plugin layer — the first run automatically initializes the web profile. You only need pnpm on your PATH:

npm install -g pnpm

--legacy-peer-deps=false makes npm resolve peer dependencies normally. If your npm config has legacy-peer-deps=true (it skips peer packages), dsh would fail to boot with ERR_MODULE_NOT_FOUND: Cannot find package '@deepseek-ai/cordis-plugin-group'. On machines without that setting the flag is a harmless no-op.

Verify the plugin layer is composed without booting:

npx --legacy-peer-deps=false @deepseek-ai/dsh --profile web --dump-config | grep -A 2 garmin-connect

Other install sources:

# Local checkout (development)
cd dsh-plugin-garmin-connect && npm install
npx --legacy-peer-deps=false @deepseek-ai/dsh plugin --profile web add .

# GitHub source install
npx --legacy-peer-deps=false @deepseek-ai/dsh plugin --profile web add github:<owner>/<repo>

2. Install the Harness CLI (if you haven't already)

npx --legacy-peer-deps=false @deepseek-ai/dsh web

The web UI starts at http://127.0.0.1:3080 by default. If you launch Harness via npx, keep using the same prefix for the commands below (npx --legacy-peer-deps=false @deepseek-ai/dsh …); if you have dsh installed globally, you can drop the npx @deepseek-ai/ prefix.

3. Configure Credentials

This plugin never stores passwords in config files or logs. Credentials are resolved through environment variables.

# Copy the template
cp .env.example .env

# Edit .env and fill in your Garmin credentials

Put the .env file in the directory you run dsh from (your workspace root) — the plugin loads it automatically.

Variable	Required	Description
`GARMIN_USERNAME`	✅	Your Garmin account email
`GARMIN_PASSWORD`	✅*	Account password
`GARMIN_SESSION_TOKEN`	✅*	Pre-authenticated token (alternative to password)
`GARMIN_REGION`	❌	`global` (default) or `cn` for Garmin China
`GARMIN_CACHE_TTL`	❌	Cache duration in seconds (default: `300`)
`GARMIN_LOG_LEVEL`	❌	`debug` \| `info` \| `warn` \| `error`
`GARMIN_ACTIVITY_DETAIL`	❌	Default detail for `get_garmin_activities`: `compact` (default, curated fields, saves context) or `full` (all raw Garmin fields)

* You need either GARMIN_PASSWORD or GARMIN_SESSION_TOKEN, not both.

⚠️ If your password contains # or other special characters, wrap it in double quotes — otherwise # and everything after it will be treated as a comment:
GARMIN_PASSWORD="my#secret!pass"

4. Run

npx --legacy-peer-deps=false @deepseek-ai/dsh web

Open http://127.0.0.1:3080. The plugin is loaded when Settings → Plugins → Plugin list shows plugin-garmin-connect as mounted & enabled. Then try: "How was my sleep last night?" or "Show me my last 5 runs."

5. Integration Test (optional)

After configuring .env, you can run the integration test to verify all API connections:

npm run test:integration

Security

Your credentials never leave your machine.

Credential Resolution Order

1. Plugin config values (set on the plugin row in a profile patch / `--patch` overlay)
   ↓ fallback
2. Environment variables (.env / shell)
   ↓ fallback
3. Schema defaults

Best Practices

Practice	Status
Passwords loaded exclusively from `process.env`	✅
`.env` is in `.gitignore`	✅
Secrets marked with `role('secret')` in Cordis schema — excluded from trajectory logs	✅
Session token support — avoids storing password entirely	✅
Tool outputs never include raw credentials	✅
In-memory cache reduces API calls (rate-limit protection)	✅

Recommended: Use Session Tokens

For maximum security, log in once with a password, then export and store only the session token:

You (to DeepSeek agent): "Export my Garmin session token"

# Agent calls: export_garmin_session
# → Returns a token string

# Add to .env:
GARMIN_SESSION_TOKEN=<the-token>
# Remove the password:
# GARMIN_PASSWORD=

Use with Other AI Coding Agents (MCP)

This plugin also ships as a standalone MCP (Model Context Protocol) server, so you can use the same Garmin tools with Claude Desktop, Codex CLI, Cursor, Windsurf, and any other MCP-compatible client — no DeepSeek Harness required.

Claude Desktop

Edit ~/.claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "garmin-connect": {
      "command": "npx",
      "args": ["-y", "dsh-plugin-garmin-connect", "garmin-connect-mcp"],
      "env": {
        "GARMIN_USERNAME": "your@email.com",
        "GARMIN_PASSWORD": "yourpassword",
        "GARMIN_REGION": "global"
      }
    }
  }
}

Restart Claude Desktop. You'll see a 🔌 icon indicating the tools are loaded. Try: "Show my last 5 runs" or "Create a threshold workout and sync to my watch".

Cursor / Windsurf

Open Settings → MCP Servers → Add Server
Name: garmin-connect
Type: stdio
Command: npx -y dsh-plugin-garmin-connect garmin-connect-mcp
Add environment variables: GARMIN_USERNAME, GARMIN_PASSWORD, GARMIN_REGION

OpenAI Codex CLI

Add to your .codex/config.json:

{
  "mcpServers": {
    "garmin-connect": {
      "command": "npx",
      "args": ["-y", "dsh-plugin-garmin-connect", "garmin-connect-mcp"],
      "env": {
        "GARMIN_USERNAME": "your@email.com",
        "GARMIN_PASSWORD": "yourpassword"
      }
    }
  }
}

Local Development / Manual Run

# Clone and build
git clone https://github.com/Likenttt/garmin-connect-plugin-for-dsh.git
cd dsh-plugin-garmin-connect && npm install && npm run build

# Run the MCP server (stdin/stdout)
GARMIN_USERNAME=xxx GARMIN_PASSWORD=xxx node lib/mcp.js

The MCP server exposes all 10 tools (activities, sleep, steps, heart rate, weight, workouts, profile, session export, running skills, and workout creation) through standard MCP protocol.

Publishing & Distribution

The package is a standard dsh bundle: package.json declares dsh.bundle.patch → cordis.patch.yml, and files ships the compiled lib/, both READMEs, and the patch file.

npm run build   # prepublishOnly also runs this automatically
npm publish

After publishing, users install with a single command:

npx --legacy-peer-deps=false @deepseek-ai/dsh plugin --profile web add dsh-plugin-garmin-connect

Distribution notes:

npm registry (recommended) — the tarball ships prebuilt lib/, so no build permission is needed at install time.
Local checkout — npx --legacy-peer-deps=false @deepseek-ai/dsh plugin --profile web add . links the source directory; run npm install first.
GitHub installs — npx --legacy-peer-deps=false @deepseek-ai/dsh plugin --profile web add github:<owner>/<repo> fetches sources and runs the package's prepare script to build them (self-contained, pinned TypeScript via npx); pnpm ≥ 10 refuses to run the script until you allow it — dsh prints the exact allowBuilds key for the profile's pnpm-workspace.yaml.
Add the dsh-plugin topic to your GitHub repository for discoverability.
