WHAT IT DOES

What create_style does on Docx

AI agents use create_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 create_style is rated Medium

Creating a style is a write operation that modifies document structure reversibly. While styles can affect document appearance and behavior, they are not financial transactions, do not execute code, and can be deleted or modified later.

From the tool's definition Tool name is 'create_style' which by definition creates new content (a style definition). Server description confirms 'editing...Microsoft Word documents' and 'document manipulation'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_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 create_style, this is the rule to start with:

create_style Rate-limited

create_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.
