Why generate_mac_address needs a policy

This tool generates a random MAC address locally. It doesn't read external data, write/modify any state, execute commands, delete anything, or involve financial operations. It's a pure local computation/generation utility with no side effects.

POLICY

How to control generate_mac_address

PolicyLayer is an MCP gateway — it sits between your AI agents and IT Tools MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_mac_address:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_mac_address": {
      "limits": [
        {
          "counter": "generate_mac_address_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_mac_address gets a rate cap, and everything else on the server is denied unless you say otherwise.
