AI agents use move_page_item 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.
Moving a page item is a reversible modification operation that alters the document state but does not delete data or execute arbitrary code. It fits the Write category (creates or modifies data reversibly). Severity is medium because misuse could corrupt document layouts or user intent, but the change is undoable and does not directly destroy data, execute external code, or commit financial transactions.
From the tool's definition Tool name is 'move_page_item' with description 'Move a page item to a new position'. This operation modifies the spatial/layout properties of an existing object within an InDesign document, changing its position/location reversibly.
Documented attack patterns abuse exactly the kind of access move_page_item 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 move_page_item:
{
"version": "1",
"default": "deny",
"tools": {
"move_page_item": {
"limits": [
{
"counter": "move_page_item_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}move_page_item 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.

Move a page item to a new position. 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 move_page_item: 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.
move_page_item 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 move_page_item 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 move_page_item. 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.
move_page_item 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.
