garth-mcp-server

Garmin Connect MCP server based on garth.

Usage

Related MCP server: garmin-connect-mcp

Install

{
  "mcpServers": {
    "Garth - Garmin Connect": {
      "command": "uvx",
      "args": [
        "garth-mcp-server"
      ],
      "env": {
        "GARTH_TOKEN": "<output of `uvx garth login`>"
      }
    }
  }
}

Make sure the path for the uvx command is fully scoped as MCP doesn't use the same PATH your shell does. On macOS, it's typically /Users/{user}/.local/bin/uvx.

Tool Filtering

By default, all 30 tools are exposed. To reduce context size for LLM usage, you can filter tools using environment variables.

Enable specific tools only (whitelist)

{
  "mcpServers": {
    "Garth - Garmin Connect": {
      "command": "uvx",
      "args": ["garth-mcp-server"],

        "GARTH_ENABLED_TOOLS": "get_activities,get_activity_details,daily_steps,nightly_sleep"
      }
    }
  }
}

Disable specific tools (blacklist)

"env": {
  "GARTH_TOKEN": "<token>",
  "GARTH_DISABLED_TOOLS": "get_gear,get_gear_stats,get_device_settings,get_connectapi_endpoint"
}

Tool names are case-insensitive and comma-separated. If GARTH_ENABLED_TOOLS is set, GARTH_DISABLED_TOOLS is ignored.
