rename_folder · PromptingBox MCP Server MCP: Risk & Policy

WHAT IT DOES

What rename_folder does on PromptingBox MCP Server

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

WHY IT NEEDS A POLICY

Why rename_folder needs a policy

Renaming a folder is a reversible write operation. It modifies metadata but does not execute code, delete data, move money, or cause irreversible changes. The impact is limited to folder organization within PromptingBox. Severity is low because misuse would only clutter the user's folder structure, which can be easily corrected.

From the tool's definition Tool description states "Rename an existing folder" — a modification operation that changes folder metadata. The name and description indicate this reversibly updates data (folder name) without deletion or execution of code.
