AI agents use create_text_frame to create or update resources in InDesign MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your InDesign MCP Server environment.
This tool creates new content (a text frame) within a document, which is a reversible modification. It does not execute arbitrary code, delete data, or move money. While it modifies the document state, the action is not destructive—text frames can be removed or edited.
From the tool's definition Tool name 'create_text_frame' and description 'Create a text frame on the active page' indicate creation of a new design element within an InDesign document.
Documented attack patterns abuse exactly the kind of access create_text_frame 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 create_text_frame:
{
"version": "1",
"default": "deny",
"tools": {
"create_text_frame": {
"limits": [
{
"counter": "create_text_frame_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} create_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 text frame on the active page. It is categorised as a Write tool in the InDesign MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the InDesign MCP Server MCP server in PolicyLayer and add a rule for create_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 MCP Server. Nothing to install.
create_text_frame is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_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.
Set action: deny in the PolicyLayer policy for create_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.
create_text_frame 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.
