WHAT IT DOES

What calculate_bmi does on GadgetHumans API Hub

AI agents call calculate_bmi 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 calculate_bmi is rated Low

This is a mathematical utility that takes numeric inputs (weight and height) and returns a computed value (BMI). It has no side effects, does not modify any data, does not execute code or commands, and does not involve financial transactions. It fits the Read category as a data computation/retrieval tool with minimal security risk.

From the tool's definition Tool description states 'Calculate BMI (Body Mass Index) from weight and height' - a pure computation that retrieves a calculated result without modifying, deleting, or executing external operations.

RECOMMENDED RULE

The rule that runs calculate_bmi 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 calculate_bmi, this is the rule to start with:

calculate_bmi Allowed

calculate_bmi 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": {
    "calculate_bmi": {}
  }
}

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 calculate_bmi call is checked against it from then on.
