AI agents use export_pdf 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.
This tool creates/writes a new file output (PDF) that persists, which is a reversible modification (the PDF can be deleted, the original InDesign document remains unmodified). It does not execute arbitrary code, trigger external operations with unpredictable effects, or irreversibly destroy data.
From the tool's definition Tool name 'export_pdf' and description 'Export document to PDF' indicate creation of a new file artifact (PDF output) from the current InDesign document state.
Documented attack patterns abuse exactly the kind of access export_pdf 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 export_pdf:
{
"version": "1",
"default": "deny",
"tools": {
"export_pdf": {
"limits": [
{
"counter": "export_pdf_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}export_pdf 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.
Free to start. No card required.
Export document to PDF. 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 export_pdf: 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.
export_pdf 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 export_pdf 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 export_pdf. 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.
export_pdf 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.
