WHAT IT DOES

What heart_rate_zones does on GadgetHumans API Hub

AI agents call heart_rate_zones to retrieve information from GadgetHumans API Hub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why heart_rate_zones is rated Low

This tool performs a mathematical calculation based on input parameters (likely age, max heart rate, or exercise intensity) and returns computed heart rate zone recommendations. It has no side effects, does not create, modify, or delete data, and does not execute external operations or commit financial obligations. It is a pure computational utility consistent with the other utility APIs in this server.

From the tool's definition Tool name 'heart_rate_zones' and description 'Calculate target heart rate zones for exercise' indicate a read-only calculation operation that retrieves or computes fitness data without modifying any state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs heart_rate_zones safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GadgetHumans API Hub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For heart_rate_zones, this is the rule to start with:

heart_rate_zones Allowed

heart_rate_zones is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "heart_rate_zones": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GadgetHumans API Hub, apply this rule, and every heart_rate_zones call is checked against it from then on.
