AI agents use export_images 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.
Export operations generate new files (image outputs) from existing document pages. While reversible (exported files can be deleted), this is a write operation that produces new artifacts. Severity is medium because uncontrolled exports could flood storage or create unintended intellectual property exposure.
From the tool's definition Tool: 'export_images' with description 'Export pages as images'. This creates new image files from InDesign pages, constituting data creation/output without deletion or reversal issues.
Documented attack patterns abuse exactly the kind of access export_images 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 export_images:
{
"version": "1",
"default": "deny",
"tools": {
"export_images": {
"limits": [
{
"counter": "export_images_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}export_images 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.

Export pages as images. 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 export_images: 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.
export_images 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 export_images 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 export_images. 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.
export_images 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.
