WHAT IT DOES

What whois_check does on Osint Terminal

AI agents call whois_check to retrieve information from Osint Terminal without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`q`	string	—

Parameters from the server's own tool schema.

RISK

Why whois_check is rated Low

Even though whois_check only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs whois_check safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Osint Terminal, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For whois_check, this is the rule to start with:

whois_check Allowed

whois_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": {
    "whois_check": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Osint Terminal, apply this rule, and every whois_check call is checked against it from then on.
