What set_physics_layers does on Godot
AI agents use set_physics_layers to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
mask | integer | — | Collision mask (1-32) |
path | string | Yes | Node with collision object |
layer | integer | — | Collision layer (1-32) |
Parameters from the server's own tool schema.
Why set_physics_layers is rated Medium
This tool modifies physics configuration on a node (collision layers and masks), which affects game behavior but is reversible—properties can be changed back. It does not execute code, delete data, or cause financial impact. The 'set' operation classifies it as Write.
From the tool's definition Tool name 'set_physics_layers' and description 'Set physics collision layers and masks on a node' indicate modification of node properties in a Godot game engine context.

The rule that runs set_physics_layers safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_physics_layers, this is the rule to start with:
set_physics_layers 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, apply this rule, and every set_physics_layers call is checked against it from then on.
Questions about set_physics_layers
Set physics collision layers and masks on a node. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
set_physics_layers accepts 3 parameters: mask, path, layer. Required: path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for set_physics_layers: 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. Nothing to install.
set_physics_layers 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 set_physics_layers 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 set_physics_layers. 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.
set_physics_layers is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
