add_paragraph · Wps MCP: Risk & Policy

WHAT IT DOES

What add_paragraph does on Wps

AI agents use add_paragraph 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 add_paragraph needs a policy

This tool creates or modifies document content reversibly. It does not delete data (not Destructive), execute arbitrary code (not Execute), move money (not Financial), or merely retrieve data (not Read). Write is the appropriate category. Severity is medium because an AI agent misusing this could generate unwanted or malicious text content in documents, but the effect is reversible via undo or deletion.

From the tool's definition Tool name 'add_paragraph' and description 'Add a paragraph to an existing document' indicate creation/modification of document content. The server enables 'create and edit WPS Office documents' via natural language commands.

Verdict

add_paragraph Rate-limited

add_paragraph 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.
