Adjust page layout with new dimensions and margins
AI agents use adjust_page_layout to create or update resources in InDesign UXP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your InDesign UXP MCP Server environment.
This tool modifies existing document properties (page dimensions and margins) in a reversible manner. These changes can be undone in InDesign and do not permanently destroy data or execute arbitrary code. The impact is scoped to layout properties within the current document. Severity is medium because incorrect dimensions/margins could require cleanup work but are not irreversible or critical system operations.
From the tool's definition Tool name 'adjust_page_layout' combined with description 'Adjust page layout with new dimensions and margins' indicates modification of document structure parameters.
Documented attack patterns abuse exactly the kind of access adjust_page_layout 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 adjust_page_layout:
{
"version": "1",
"default": "deny",
"tools": {
"adjust_page_layout": {
"limits": [
{
"counter": "adjust_page_layout_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}adjust_page_layout 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.

Adjust page layout with new dimensions and margins. It is categorised as a Write tool in the InDesign UXP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the InDesign UXP MCP Server MCP server in PolicyLayer and add a rule for adjust_page_layout: 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.
adjust_page_layout 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 adjust_page_layout 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 adjust_page_layout. 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.
adjust_page_layout 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.
