Set layout preferences for the document
AI agents use set_document_layout_preferences 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 document layout preferences, which are configuration settings that can be changed back or undone in InDesign. It is not a destructive operation (preferences can be reset), not an execute operation (it doesn't run arbitrary code or trigger external processes), and not a read operation (it changes state).
From the tool's definition Tool name 'set_document_layout_preferences' and description 'Set layout preferences for the document' indicate modification of document configuration settings.

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

Register the InDesign UXP MCP Server MCP server in PolicyLayer and add a rule for set_document_layout_preferences: 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.
set_document_layout_preferences 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 set_document_layout_preferences 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 set_document_layout_preferences. 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.
set_document_layout_preferences 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.
