## Why add_post_process is rated Medium

This tool creates or modifies post-processing effects in the s&box game scene. These are reversible changes to visual rendering parameters—not deletions or irreversible alterations. An agent could misuse this to degrade visual quality or create disorienting effects, but the impact is limited to scene aesthetics and can be undone.

From the tool's own definition: "Tool name 'add_post_process' and description 'Add (or update) a post-processing effect on the scene' indicate creation or modification of scene visual effects."

## Use case

AI agents use add_post_process 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sbox:
