create_document · Wps MCP: Risk & Policy

WHAT IT DOES

What create_document does on Wps

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

WHY IT NEEDS A POLICY

Why create_document needs a policy

This tool creates a new document, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. While document creation is a write action, the severity is medium rather than low because creating documents could be used to generate large numbers of files, clutter workspaces, or create misleading content if an AI agent is compromised.

From the tool's definition Tool name 'create_document' and description 'Create a new WPS Word document' indicate creation of new data/files.
