AI agents call list_page_items to retrieve information from InDesign UXP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about page items without creating, modifying, deleting, or executing any operations. It is a passive read operation on an InDesign document's page structure, posing minimal security risk.
From the tool's definition Tool name 'list_page_items' and description 'List all page items on a specific page' indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_page_items gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and InDesign UXP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_page_items:
{
"version": "1",
"default": "deny",
"tools": {
"list_page_items": {}
}
}list_page_items is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all page items on a specific page. It is categorised as a Read tool in the InDesign UXP MCP Server MCP Server, which means it retrieves data without modifying state.
Register the InDesign UXP MCP Server MCP server in PolicyLayer and add a rule for list_page_items: 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 InDesign UXP MCP Server. Nothing to install.
list_page_items is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_page_items 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.
Set action: deny in the PolicyLayer policy for list_page_items. 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.
list_page_items is provided by the InDesign UXP MCP Server MCP server (theloniuser/indesign-uxp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
