What add_forest_poi does on Sbox
AI agents use add_forest_poi to create or update resources in Sbox, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sbox environment.
Why add_forest_poi is rated Medium
This tool creates new data within the game engine by adding a POI entry to a generator system. The action is reversible (POIs can be removed or modified), so it falls under Write rather than Execute or Destructive. Severity is medium because misuse could clutter the game world with unwanted POIs, but the effect is limited in scope and not catastrophic.
From the tool's definition Tool description states 'Add a point of interest (clearing) to ForestGenerator.POIs' and 'Returns the index of the new POI', indicating creation/modification of game world data structure.
Attacks that exploit this kind of access
The rule that runs add_forest_poi safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sbox, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_forest_poi, this is the rule to start with:
add_forest_poi 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Sbox, apply this rule, and every add_forest_poi call is checked against it from then on.
