AI agents call list_shader_node_types to retrieve information from Godot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This tool retrieves information about available shader node types in Godot's VisualShader system. It is a read-only operation that queries existing data structures and returns organized results. There are no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an AI agent could only retrieve information it would typically access through normal API inspection.

Attacks that exploit this kind of access
List all VisualShader node types organized by category with input/output counts. It is categorised as a Read tool in the Godot MCP Server, which means it retrieves data without modifying state.
list_shader_node_types accepts 1 parameter: category. 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_shader_node_types: 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_shader_node_types 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_shader_node_types 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_shader_node_types. 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_shader_node_types 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.
list_shader_node_types is one line of Godot's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
