Create a group from specific page items by their indices
AI agents use create_group_from_items 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 creates a new grouping structure from existing items, which modifies the document's object hierarchy and layout organization. It is reversible (groups can be ungrouped), so it falls under Write rather than Destructive. The severity is medium because misuse could restructure a document's composition, affecting layout and design intent, but the change is undoable.
From the tool's definition Tool name 'create_group_from_items' and description 'Create a group from specific page items by their indices' indicate creation of a new structural element (grouping) in InDesign document.
Documented attack patterns abuse exactly the kind of access create_group_from_items 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 create_group_from_items:
{
"version": "1",
"default": "deny",
"tools": {
"create_group_from_items": {
"limits": [
{
"counter": "create_group_from_items_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_group_from_items 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 group from specific page items by their indices. 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 create_group_from_items: 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.
create_group_from_items 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_group_from_items 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_group_from_items. 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_group_from_items 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.
