WHAT IT DOES

What proportion_calc does on GadgetHumans API Hub

AI agents call proportion_calc 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 proportion_calc is rated Low

This is a stateless mathematical utility that retrieves a computed result. It does not create, modify, delete, or execute any external operations. It matches the Read category as a pure query/calculation tool with no mutations or side effects.

From the tool's definition Tool performs mathematical calculation (solving proportions) with no side effects, data modification, or external operations. The operation is purely computational: given inputs in the form a:b = c:d, it returns the missing term.

RECOMMENDED RULE

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

proportion_calc Allowed

proportion_calc 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": {
    "proportion_calc": {}
  }
}

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 proportion_calc call is checked against it from then on.

FAQ

Questions about proportion_calc

What does the proportion_calc tool do? +

Solve proportion: find missing term in a:b = c:d. It is categorised as a Read tool in the GadgetHumans API Hub MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on proportion_calc? +

Register the GadgetHumans API Hub MCP server in PolicyLayer and add a rule for proportion_calc: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GadgetHumans API Hub. Nothing to install.

What risk level is proportion_calc? +

proportion_calc is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit proportion_calc? +

Yes. Add a rate_limit block to the proportion_calc rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block proportion_calc completely? +

Set action: deny in the PolicyLayer policy for proportion_calc. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides proportion_calc? +

proportion_calc is provided by the GadgetHumans API Hub MCP server (pypi:gadgethumans-api-hub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
