What particles_set_emitting does on Godot Breakpoint
AI agents use particles_set_emitting 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 particles_set_emitting is rated Medium
This tool modifies scene state reversibly (particles emitting property can be toggled on/off and undone), making it a Write operation rather than Execute or Destructive. The 'undoable' qualifier confirms reversibility. Severity is medium because while an agent could spam particle emission to degrade performance or confuse scene state, the change is non-destructive and easily recoverable.
From the tool's definition Tool description states it toggles a property ('Toggle whether a GPUParticles2D/3D is emitting') and explicitly notes '(undoable)', indicating the change is reversible through undo functionality.
Attacks that exploit this kind of access
The rule that runs particles_set_emitting 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 particles_set_emitting, this is the rule to start with:
particles_set_emitting 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 particles_set_emitting call is checked against it from then on.
Questions about particles_set_emitting
Toggle whether a GPUParticles2D/3D is emitting in the edited scene (undoable). In-scene and undoable — not gated. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for particles_set_emitting: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot Breakpoint. Nothing to install.
particles_set_emitting is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the particles_set_emitting rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for particles_set_emitting. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
particles_set_emitting is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
