What mp_setup_webrtc_peer does on Godot Breakpoint
AI agents use mp_setup_webrtc_peer to create or update resources in Godot Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Breakpoint environment.
Why mp_setup_webrtc_peer is rated Medium
This tool generates (writes/creates) a GDScript helper script for configuring WebRTC multiplayer. It creates new code/configuration rather than reading existing data, executing commands, or destroying anything. The severity is medium because generated networking code could introduce security misconfigurations if misused, but the action itself is a reversible write operation.

The rule that runs mp_setup_webrtc_peer safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mp_setup_webrtc_peer, this is the rule to start with:
mp_setup_webrtc_peer 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 Godot Breakpoint, apply this rule, and every mp_setup_webrtc_peer call is checked against it from then on.
