WHAT IT DOES

What ipv4_subnet does on GadgetHumans API Hub

AI agents call ipv4_subnet 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 ipv4_subnet is rated Low

The tool takes IPv4 subnet parameters as input and returns calculated network topology information. This is a read-only utility that queries/computes network information without modifying any systems, data, or triggering external actions. It belongs in the Read category (retrieves/queries data with no side effects).

From the tool's definition Tool performs calculations on IPv4 subnet information (network, broadcast, hosts) - a pure computational/query operation with no side effects, no data modification, and no external operations triggered.

RECOMMENDED RULE

The rule that runs ipv4_subnet 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 ipv4_subnet, this is the rule to start with:

ipv4_subnet Allowed

ipv4_subnet 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": {
    "ipv4_subnet": {}
  }
}

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 ipv4_subnet call is checked against it from then on.

FAQ

Questions about ipv4_subnet

What does the ipv4_subnet tool do? +

Calculate IPv4 subnet information: network, broadcast, hosts. 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 ipv4_subnet? +

Register the GadgetHumans API Hub MCP server in PolicyLayer and add a rule for ipv4_subnet: 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 ipv4_subnet? +

ipv4_subnet is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit ipv4_subnet? +

Yes. Add a rate_limit block to the ipv4_subnet 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 ipv4_subnet completely? +

Set action: deny in the PolicyLayer policy for ipv4_subnet. 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 ipv4_subnet? +

ipv4_subnet 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.
