What list_physics_materials does on Godot
AI agents call list_physics_materials 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.

Why list_physics_materials is rated Low
This tool retrieves or enumerates PhysicsMaterials from the Godot engine, which is a read-only operation with no side effects. It does not create, modify, delete, execute code, or perform financial operations. The low severity reflects minimal blast radius if misused—an agent could only discover what physics materials exist in the project.
From the tool's definition Tool name 'list_physics_materials' and description 'List PhysicsMaterials' indicate a retrieval operation with the verb 'list', which queries existing data without modification.

The rule that runs list_physics_materials 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 list_physics_materials, this is the rule to start with:
list_physics_materials 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 list_physics_materials call is checked against it from then on.
Questions about list_physics_materials
list_physics_materials is a read tool on the Godot MCP server. It is categorised as a Read tool in the Godot MCP Server, which means it retrieves data without modifying state.
list_physics_materials accepts 1 parameter: 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 list_physics_materials: 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.
list_physics_materials 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 list_physics_materials 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 list_physics_materials. 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.
list_physics_materials is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
