Why get_spread_content_summary needs a policy

This tool retrieves and summarizes information about design content within an InDesign spread. It performs no mutations, destructive operations, code execution, or financial transactions. It is a straightforward read operation with minimal security risk—the worst case being exposure of design document content, which has low blast radius.

From the tool's definition Tool name 'get_spread_content_summary' and description 'Get a summary of content on a spread' indicate a retrieval operation. The verb 'get' and 'summary' clearly denote querying/reading existing data without modification, deletion, or execution of code.

POLICY

How to control get_spread_content_summary

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_spread_content_summary:

policy.json

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

get_spread_content_summary is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register InDesign MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
