THE RISK

Medium Risk

Why edit_text_frame needs a policy

This tool modifies existing document elements (text frame properties) within Adobe InDesign, which is a reversible write operation. It does not delete data (thus not Destructive), does not execute arbitrary code (thus not Execute), and does not involve financial transactions. The medium severity reflects that misuse could corrupt or alter document layouts, but changes can typically be undone in InDesign.

From the tool's definition Tool name 'edit_text_frame' combined with description 'Edit properties of an existing text frame' indicates modification of document content.

POLICY

How to control edit_text_frame

PolicyLayer is an MCP gateway — it sits between your AI agents and Indesign, and nothing reaches the server without passing your rules. This is the rule we recommend for edit_text_frame:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "edit_text_frame": {
      "limits": [
        {
          "counter": "edit_text_frame_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

edit_text_frame stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about edit_text_frame

What does the edit_text_frame tool do? +

Edit properties of an existing text frame. It is categorised as a Write tool in the Indesign MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on edit_text_frame? +

Register the Indesign MCP server in PolicyLayer and add a rule for edit_text_frame: 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. Nothing to install.

What risk level is edit_text_frame? +

edit_text_frame is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit edit_text_frame? +

Yes. Add a rate_limit block to the edit_text_frame 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.

How do I block edit_text_frame completely? +

Set action: deny in the PolicyLayer policy for edit_text_frame. 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.

What MCP server provides edit_text_frame? +

edit_text_frame is provided by the Indesign MCP server (lucdesign/indesign-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Indesign tool call.

Start from Indesign, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
