Open a document from Adobe Creative Cloud
AI agents use open_cloud_document 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.
While 'open' by itself is a read action, in the context of InDesign's UXP plugin bridge where this is part of a tool suite with ~130 tools covering document manipulation, opening a document prepares it for modification and editing.
From the tool's definition Opens a document from Adobe Creative Cloud, which loads the document into the active editing session, making it available for modification. The description indicates it retrieves and activates a document for potential write operations.
Documented attack patterns abuse exactly the kind of access open_cloud_document 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 open_cloud_document:
{
"version": "1",
"default": "deny",
"tools": {
"open_cloud_document": {
"limits": [
{
"counter": "open_cloud_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}open_cloud_document 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.

Open a document from Adobe Creative Cloud. 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 open_cloud_document: 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.
open_cloud_document 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 open_cloud_document 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 open_cloud_document. 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.
open_cloud_document 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.
