AI agents use ungroup 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.
The tool modifies document state by ungrouping objects, which is a Write operation (reversible restructuring). It has medium severity because ungrouping can change layout and object relationships in ways an AI might not intend, but it is not destructive (can be undone) and does not delete data. In the context of an InDesign document manipulation server, this is a typical document edit operation.
From the tool's definition ungroup — 'releasing all its items' modifies the document structure by dissolving a group container, which is a reversible structural change to the document.
Documented attack patterns abuse exactly the kind of access ungroup 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 ungroup:
{
"version": "1",
"default": "deny",
"tools": {
"ungroup": {
"limits": [
{
"counter": "ungroup_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ungroup 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.

Ungroup a group, releasing all its items. 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 ungroup: 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.
ungroup 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 ungroup 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 ungroup. 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.
ungroup 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.
