patch_folder · Smokeball MCP: Risk & Policy

WHAT IT DOES

What patch_folder does on Smokeball

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

WHY IT NEEDS A POLICY

Why patch_folder needs a policy

Moving a folder to a different parent changes metadata and organizational state within the system. This is a Write operation because it modifies data structure reversibly—the folder can be moved again to restore prior state. It is not Execute (no external operations), Destructive (reversible), or Financial.

From the tool's definition patch_folder: Move a folder to a different parent. This operation modifies the organizational structure by relocating a folder, which is reversible but represents a data modification action.

Verdict

patch_folder Rate-limited

patch_folder 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.
