toggle_save_datapack · OPanel MCP: Risk & Policy

WHAT IT DOES

What toggle_save_datapack does on OPanel MCP

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

WHY IT NEEDS A POLICY

Why toggle_save_datapack needs a policy

Toggling a datapack changes server configuration state but is reversible (can be toggled back on). This is a modification action that fits Write rather than Execute (no arbitrary code execution) or Destructive (changes are not permanent/irreversible). Severity is medium because misconfiguration could degrade server performance or functionality, but the effect is localized to one datapack and reversible.

From the tool's definition Tool description states 'Enable or disable a datapack' — this modifies the state of server configuration (datapack settings) reversibly without permanently deleting data or executing arbitrary code.
