WHAT IT DOES

What calculate_combinations does on GadgetHumans API Hub

AI agents call calculate_combinations 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_combinations is rated Low

This is a read-only utility that takes numerical inputs and returns calculated results. It does not create, modify, delete, or execute any operations. The mathematical computation is deterministic and does not affect any data, files, or external systems. The blast radius of misuse is minimal since the outputs are harmless numerical results.

From the tool's definition The tool 'calculate_combinations' performs mathematical calculations of nCr (combinations) and nPr (permutations) — purely computational operations that retrieve or derive numerical results with no side effects, data modifications, or external state changes.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

calculate_combinations Allowed

calculate_combinations 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_combinations": {}
  }
}

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_combinations call is checked against it from then on.

FAQ

Questions about calculate_combinations

What does the calculate_combinations tool do? +

Calculate nCr (combinations) and nPr (permutations) for given 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 calculate_combinations? +

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

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

Can I rate-limit calculate_combinations? +

Yes. Add a rate_limit block to the calculate_combinations 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 calculate_combinations completely? +

Set action: deny in the PolicyLayer policy for calculate_combinations. 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 calculate_combinations? +

calculate_combinations 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.
