Close the current document
AI agents use close_document to create or update resources in Indesign — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Indesign environment.
This tool modifies application state by closing a document, making it a Write operation rather than Read (no side effects). It is not Destructive because closing a document does not irreversibly delete data—the file remains. It is not Execute because it doesn't run arbitrary code.
From the tool's definition close_document closes the current document, which modifies the application state. The tool does not irreversibly delete data if the document is saved, but it affects the document's open/closed state and may affect unsaved changes depending on implementation.
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, 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 current document. It is categorised as a Write tool in the Indesign MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Indesign 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. 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 MCP server (lucdesign/indesign-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Indesign, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
