WHAT IT DOES

What list_device_categories does on Zype Com

AI agents call list_device_categories to retrieve information from Zype Com 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
`page`	number	—	page
`title`	string	—	title
`per_page`	number	—	per_page

Parameters from the server's own tool schema.

RISK

Why list_device_categories is rated Low

Even though list_device_categories 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 list_device_categories safely

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

list_device_categories Allowed

list_device_categories is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_device_categories": {}
  }
}

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

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