set_particle_property · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What set_particle_property does on Godot MCP Server

AI agents use set_particle_property 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 set_particle_property needs a policy

This tool modifies particle node properties in the Godot editor, which is a reversible change (properties can be changed back). It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read).

From the tool's definition Tool name 'set_particle_property' and description 'Set a single property on a particle node' indicate modification of game object state. The verb 'set' and action of property modification are characteristic of Write operations that reversibly change data.

Verdict

set_particle_property Rate-limited

set_particle_property 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 set_particle_property

What does the set_particle_property tool do? +

Set a single property on a particle node. 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 set_particle_property? +

Register the Godot MCP Server MCP server in PolicyLayer and add a rule for set_particle_property: 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 set_particle_property? +

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

Can I rate-limit set_particle_property? +

Yes. Add a rate_limit block to the set_particle_property 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 set_particle_property completely? +

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

set_particle_property 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.
