WHAT IT DOES

What port_check does on GadgetHumans API Hub

AI agents call port_check 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 port_check is rated Low

This tool performs reconnaissance by testing port availability, which is a read-only diagnostic operation. While port scanning can inform malicious activity, the tool itself does not execute commands, modify data, or trigger external changes. It falls clearly into the Read category as it only queries and reports network state.

From the tool's definition Tool description states 'Check if a network port is open on a host' — a pure query operation that retrieves network status information with no side effects, modification, or code execution.

RECOMMENDED RULE

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

port_check Allowed

port_check 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": {
    "port_check": {}
  }
}

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 port_check call is checked against it from then on.

How do I enforce a policy on port_check? +

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

Can I rate-limit port_check? +

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

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

port_check 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.
