WHAT IT DOES

What density_calc does on GadgetHumans API Hub

AI agents call density_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 density_calc is rated Low

This is a mathematical utility that retrieves results based on user-supplied parameters. It does not create, modify, delete data, execute code, move money, or trigger external operations. The calculation output has no persistent state changes or irreversible consequences, making it a Read category tool with low severity.

From the tool's definition Tool performs calculations on provided numerical inputs (density, mass, or volume) with no side effects, data modification, or external operations. Description indicates pure computation: 'Calculate density, mass, or volume given any two values.'

Attacks that exploit this kind of access

RECOMMENDED RULE

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

density_calc Allowed

density_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": {
    "density_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 density_calc call is checked against it from then on.

FAQ

Questions about density_calc

What does the density_calc tool do? +

Calculate density, mass, or volume given any two values. 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 density_calc? +

Register the GadgetHumans API Hub MCP server in PolicyLayer and add a rule for density_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 density_calc? +

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

Can I rate-limit density_calc? +

Yes. Add a rate_limit block to the density_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 density_calc completely? +

Set action: deny in the PolicyLayer policy for density_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 density_calc? +

density_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.
