AI agents use word_setPaperSize to create or update resources in MCP Office Interop Word Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Office Interop Word Server environment.
This tool creates or modifies document metadata/settings (paper size) without destroying data or executing arbitrary code. The change is reversible—a user can easily set the paper size to a different value. While it affects document properties, it does not delete content, execute external operations, or involve financial transactions.
From the tool's definition The tool 'word_setPaperSize' modifies document properties by setting the paper size using WdPaperSize enum values. This is a reversible configuration change to an active Word document.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Office Interop Word Server, and nothing reaches the server without passing your rules. This is the rule we recommend for word_setPaperSize:
{
"version": "1",
"default": "deny",
"tools": {
"word_setPaperSize": {
"limits": [
{
"counter": "word_setpapersize_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}word_setPaperSize 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.
