Get a list of categories with filtering options
AI agents call list-categories to retrieve information from WordPress MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation to retrieve category data from WordPress. The verb 'Get a list' and 'filtering options' are characteristic of read-only operations that do not modify, execute, or delete any data. No authentication bypass, data exfiltration of sensitive user information, or ability to enumerate private posts is evident from the description alone, making this a standard low-risk read operation.
From the tool's definition Tool name 'list-categories' and description 'Get a list of categories with filtering options' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list-categories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and WordPress MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-categories:
{
"version": "1",
"default": "deny",
"tools": {
"list-categories": {}
}
}list-categories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
