AI agents call get_document_styles to retrieve information from InDesign 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 style information from an InDesign document. It performs a read-only query operation that does not create, modify, delete, or execute any actions. The outcome is purely informational, with no blast radius if misused — an AI agent cannot cause harm by reading styles. Confidence is high because the name and description are explicit and unambiguous.
From the tool's definition Tool is named 'get_document_styles' and described as 'Get all styles in the document' — a retrieval operation that queries document metadata without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_document_styles gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and InDesign MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_document_styles:
{
"version": "1",
"default": "deny",
"tools": {
"get_document_styles": {}
}
}get_document_styles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all styles in the document. It is categorised as a Read tool in the InDesign MCP Server MCP Server, which means it retrieves data without modifying state.
Register the InDesign MCP Server MCP server in PolicyLayer and add a rule for get_document_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 MCP Server. Nothing to install.
get_document_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 get_document_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 get_document_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.
get_document_styles is provided by the InDesign MCP Server MCP server (zachshallbetter/indesign-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from InDesign MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
