Garmin Connect CLI

This skill provides read access to Garmin Connect health and fitness data through the gc CLI.

Setup

1. Install via Homebrew tap:

   brew tap voydz/homebrew-tap
   brew install garmin-cli
   

2. Authentication:

   gc login --email user@example.com --password secret
   # With MFA:
   gc login --email user@example.com --password secret --mfa 123456
   

3. Verify connection:

   gc status
   

Date Shortcuts

Most commands accept a date shortcut as first argument:

• today — current date
• yesterday — previous date
• week — last 7 days (returns a date range)
• month — last 30 days (returns a date range)
• YYYY-MM-DD — specific date

Alternatively use --date, --start/--end flags.

Output

All data commands support:

• --format json for machine-readable output (default: table)
• --output FILE to write to a file

Always use --format json when parsing output programmatically.
