THE RISK

Critical Risk

This tool permanently removes user health data (weight measurements) from Garmin Connect. The action is irreversible and cannot be undone through the tool's API. While the blast radius is limited to one user's weight history (not system-wide), the destruction of personal health records is a serious consequence if triggered unintentionally by an AI agent.

From the tool's definition Tool name is 'delete_weigh_ins' and description states 'Delete weight measurements for a specific date' with option to 'delete_all' measurements for the day.

HOW TO CONTROL DELETE_WEIGH_INS

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_weigh_ins"
  ]
}

delete_weigh_ins disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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