AI agents call delete_spread to permanently remove resources in InDesign UXP MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a spread in InDesign is an irreversible operation that destroys layout content, page arrangements, and associated design elements. This cannot be undone by the tool itself and represents a high blast radius if misused by an AI agent—an entire spread of work could be lost. This clearly falls under Destructive rather than Write, as it permanently removes data without possibility of reversal through the tool.
From the tool's definition Tool name is 'delete_spread' and description states 'Delete a spread'. The verb 'delete' combined with the action of removing a spread (a fundamental unit in InDesign documents containing multiple pages) indicates irreversible destruction of design work.
Documented attack patterns abuse exactly the kind of access delete_spread 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 delete_spread:
{
"version": "1",
"default": "deny",
"hide": [
"delete_spread"
]
}delete_spread disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a spread. It is categorised as a Destructive tool in the InDesign UXP MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the InDesign UXP MCP Server MCP server in PolicyLayer and add a rule for delete_spread: 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.
delete_spread is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_spread 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 delete_spread. 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.
delete_spread 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.
