Update all numbers (page numbers, chapter numbers, paragraph numbers) in a book
AI agents use update_all_numbers to create or update resources in InDesign UXP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your InDesign UXP MCP Server environment.
This tool modifies numbering fields across a multi-document book project. While reversible (a user can undo or run the tool again), it affects potentially large swaths of content in one operation. The high severity reflects the blast radius: an AI agent instructed to 'fix numbering' could inadvertently corrupt the numbering scheme in a complex book, requiring manual repair.
From the tool's definition Tool name 'update_all_numbers' and description 'Update all numbers (page numbers, chapter numbers, paragraph numbers) in a book' indicate modification of document content. The term 'update' is a reversible operation that changes existing data.
Documented attack patterns abuse exactly the kind of access update_all_numbers 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 update_all_numbers:
{
"version": "1",
"default": "deny",
"tools": {
"update_all_numbers": {
"limits": [
{
"counter": "update_all_numbers_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_all_numbers 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.

Update all numbers (page numbers, chapter numbers, paragraph numbers) in a book. It is categorised as a Write tool in the InDesign UXP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the InDesign UXP MCP Server MCP server in PolicyLayer and add a rule for update_all_numbers: 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.
update_all_numbers 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 update_all_numbers 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 update_all_numbers. 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.
update_all_numbers 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.
