create_particles · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_particles does on Godot MCP Server

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

WHY IT NEEDS A POLICY

Why create_particles needs a policy

This tool creates a new particle system node in the Godot scene, which modifies the game project state. This is a Write category action because it creates new data structures (scene nodes) that can be undone/removed. It has medium severity because while it modifies the game project, the changes are reversible and localized to particle system effects without affecting critical game logic or data.

From the tool's definition Tool description states 'Add a GPUParticles3D or CPUParticles2D node to the scene.' The action of adding/creating a node to a game scene is a write operation that modifies the scene structure reversibly.

Verdict

create_particles Rate-limited

create_particles 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.

FAQ

Questions about create_particles

What does the create_particles tool do? +

Add a GPUParticles3D or CPUParticles2D node to the scene. It is categorised as a Write tool in the Godot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_particles? +

Register the Godot MCP Server MCP server in PolicyLayer and add a rule for create_particles: 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 MCP Server. Nothing to install.

What risk level is create_particles? +

create_particles is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_particles? +

Yes. Add a rate_limit block to the create_particles 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.

How do I block create_particles completely? +

Set action: deny in the PolicyLayer policy for create_particles. 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.

What MCP server provides create_particles? +

create_particles is provided by the Godot MCP Server MCP server (neondeex/godotmcp-pro-free-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
