Close the active document. Use saveOptions to control unsaved-changes behavior.
AI agents use close_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 close_document does not permanently delete files from disk, it terminates the active document session and can discard unsaved edits based on the saveOptions parameter. This is a Write operation (reversible via undo in InDesign if changes were saved, or by reopening) rather than Destructive because the document file itself remains on disk and no data is permanently erased from storage.
From the tool's definition Tool closes the active document with a saveOptions parameter that controls whether unsaved changes are saved or discarded. This modifies document state irreversibly in memory and can affect the user's unsaved work depending on the saveOptions argument.
Documented attack patterns abuse exactly the kind of access close_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 close_document:
{
"version": "1",
"default": "deny",
"tools": {
"close_document": {
"limits": [
{
"counter": "close_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}close_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.

Close the active document. Use saveOptions to control unsaved-changes behavior. 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 close_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.
close_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 close_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 close_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.
close_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.
