WHAT IT DOES

What copy_style does on Docx

AI agents use copy_style to create or update resources in Docx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment.

RISK

Why copy_style is rated Medium

Copying a style creates new data (a style definition) but does not destroy anything or execute arbitrary code. It is reversible (the new style can be deleted) and has no external side effects.

From the tool's definition Tool description states 'Deep-copy an existing style under a new name' — this creates a new style definition by duplicating an existing one, which is a reversible modification to document metadata.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs copy_style safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Docx, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For copy_style, this is the rule to start with:

copy_style Rate-limited

copy_style 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.
