List all object styles in the document
AI agents call list_object_styles 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 retrieves existing object style metadata from an InDesign document without creating, modifying, deleting, or executing any operations. It is a pure read operation with no side effects. Severity is low because enumeration of styles poses minimal risk even if misused by an agent.
From the tool's definition Tool name is 'list_object_styles' and description states 'List all object styles in the document'—a retrieval operation with no modification, deletion, or execution.
Documented attack patterns abuse exactly the kind of access list_object_styles 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_object_styles:
{
"version": "1",
"default": "deny",
"tools": {
"list_object_styles": {}
}
}list_object_styles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all object styles in the document. 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_object_styles: 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_object_styles 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_object_styles 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_object_styles. 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_object_styles 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.
