AI agents use create_table 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.
Creating a table modifies document content (a Write operation) but is reversible—the table can be deleted or the document reverted. It does not execute arbitrary code, destroy data irreversibly, or involve financial transactions.
From the tool's definition Tool name 'create_table' with description 'Create a table' indicates content creation within an InDesign document. This is a reversible operation that adds a new table element to a document.
Documented attack patterns abuse exactly the kind of access create_table 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 create_table:
{
"version": "1",
"default": "deny",
"tools": {
"create_table": {
"limits": [
{
"counter": "create_table_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_table 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 table. 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 create_table: 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.
create_table 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_table 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_table. 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_table 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.
