Create a new section in the document
AI agents use create_document_section to create or update resources in InDesign MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your InDesign MCP Server environment.
The tool modifies the document by adding a new section, which is a reversible Write operation. It does not execute arbitrary code (Execute), delete content (Destructive), or involve financial transactions (Financial). The severity is medium because document modifications in a design tool like InDesign can affect the final output and workflows, but the change is easily undone via undo/revision control.
From the tool's definition create_document_section creates a new section in the document. This is a modification operation that adds a new structural element to the document. It follows the Write pattern of reversible creation/modification.
Documented attack patterns abuse exactly the kind of access create_document_section gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and InDesign MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_document_section:
{
"version": "1",
"default": "deny",
"tools": {
"create_document_section": {
"limits": [
{
"counter": "create_document_section_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_document_section 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.

Create a new section in the document. It is categorised as a Write tool in the InDesign MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the InDesign MCP Server MCP server in PolicyLayer and add a rule for create_document_section: 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 MCP Server. Nothing to install.
create_document_section 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 create_document_section 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 create_document_section. 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.
create_document_section is provided by the InDesign MCP Server MCP server (zachshallbetter/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 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
