WHAT IT DOES

What create_particle_material does on Godot MCP Unified

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

WHY IT NEEDS A POLICY

Why create_particle_material needs a policy

This tool creates a new ParticleProcessMaterial resource, which is a reversible write operation. The material can be modified or deleted afterward. It does not execute arbitrary code, delete existing data irreversibly, move funds, or perform destructive actions.

From the tool's definition Tool name 'create_particle_material' and description 'Create a ParticleProcessMaterial resource' indicate creation of a new resource/asset within the Godot Engine editor.

Verdict

create_particle_material Rate-limited

create_particle_material 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_particle_material

What does the create_particle_material tool do? +

Create a ParticleProcessMaterial resource for configuring GPU particle behavior. It is categorised as a Write tool in the Godot MCP Unified 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_particle_material? +

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

What risk level is create_particle_material? +

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

Can I rate-limit create_particle_material? +

Yes. Add a rate_limit block to the create_particle_material 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_particle_material completely? +

Set action: deny in the PolicyLayer policy for create_particle_material. 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_particle_material? +

create_particle_material is provided by the Godot MCP Unified MCP server (pierrealexandreguillemin-a11y/godot-mcp-unified). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
