AI agents use particle to create or update resources in Godot Devtool — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Devtool environment.
This tool creates particle emitter nodes in a Godot project, which modifies the project state reversibly. While node creation can be undone (standard undo/redo in Godot), it is a write operation that adds new scene elements. It does not execute arbitrary code, delete data irreversibly, or commit financial transactions.
From the tool's definition The tool description states 'Create and list basic Godot particle emitter nodes'. The 'create' verb indicates the tool writes/adds new nodes to a Godot project; 'list' is a read operation but the primary action is creation.
Documented attack patterns abuse exactly the kind of access particle gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Godot Devtool, and nothing reaches the server without passing your rules. This is the rule we recommend for particle:
{
"version": "1",
"default": "deny",
"tools": {
"particle": {
"limits": [
{
"counter": "particle_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}particle 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.
Free to start. No card required.
Create and list basic Godot particle emitter nodes. It is categorised as a Write tool in the Godot Devtool MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Devtool MCP server in PolicyLayer and add a rule for particle: 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 Devtool. Nothing to install.
particle 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 particle 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 particle. 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.
particle is provided by the Godot Devtool MCP server (wangdiandao/godot-devtool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
