WHAT IT DOES

What set_text_case does on Docx

AI agents use set_text_case 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 set_text_case is rated Medium

This tool modifies document content by transforming the case (capitalization) of text within a run. While reversible through undo or reapplying the transformation, it is a write operation that alters the document state.

From the tool's definition Tool name 'set_text_case' and description 'Set text case transformation on a run' indicate modification of text formatting within a Word document run (a continuous sequence of text with consistent formatting).

Attacks that exploit this kind of access

RECOMMENDED RULE

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

set_text_case Rate-limited

set_text_case 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.
