What get_physics_material does on Godot
AI agents call get_physics_material to retrieve information from Godot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
path | string | Yes | Node path in the scene tree (e.g. 'Player/Sprite2D'). Use just the node name for root-level children (e.g. 'Player'), or empty string '' for the scene root itse |
Parameters from the server's own tool schema.
Why get_physics_material is rated Low
This tool retrieves/queries physics material properties from a node without modifying, executing, or deleting anything. It is a read-only operation that poses minimal risk in the context of an AI agent interacting with a Godot game engine MCP server.
From the tool's definition Tool name is 'get_physics_material' and description states 'Get the physics material properties of a node' — 'get' is a retrieve operation with no side effects.

The rule that runs get_physics_material 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 get_physics_material, this is the rule to start with:
get_physics_material is read-only, so it stays allowed. 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 get_physics_material call is checked against it from then on.
Questions about get_physics_material
Get the physics material properties of a node. It is categorised as a Read tool in the Godot MCP Server, which means it retrieves data without modifying state.
get_physics_material accepts 1 parameter: path. 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 get_physics_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. Nothing to install.
get_physics_material is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_physics_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.
Set action: deny in the PolicyLayer policy for get_physics_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.
get_physics_material 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.
