What create_docx does on Docx
AI agents use create_docx 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.
Why create_docx is rated Medium
Creating a new document is a write operation—it generates new data and persists it to storage, but is fully reversible (the file can be deleted). There is no code execution, destructive action, or financial implication. The blast radius is minimal since the operation only creates an empty document with no side effects. Severity is low because accidental misuse (creating unwanted blank documents) causes minimal harm.
From the tool's definition Tool name is 'create_docx' and description states 'Create a new blank Word document.' This is a document creation operation that modifies the file system by adding a new file.
Attacks that exploit this kind of access
The rule that runs create_docx 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_docx, this is the rule to start with:
create_docx 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Docx, apply this rule, and every create_docx call is checked against it from then on.
