How to control get_activities ↓

AI agents call get_activities to retrieve information from Garmin Connect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool only queries and retrieves historical fitness data without side effects. It performs a read-only operation on the user's Garmin Connect data, analogous to a search or fetch operation. No data is created, modified, deleted, or executed. The pagination mechanism does not change this classification.

From the tool's definition Tool retrieves activity summaries including type, duration, distance, calories, and heart rate with no modification, deletion, or execution. The description indicates a query operation with 'Returns activity summaries' and 'Get recent activities'.

Documented attack patterns abuse exactly the kind of access get_activities gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin Connect, and nothing reaches the server without passing your rules. This is the rule we recommend for get_activities:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_activities": {}
  }
}

get_activities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Garmin Connect — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
