create_shader · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_shader does on Godot MCP Server

AI agents use create_shader to create or update resources in Godot MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot MCP Server environment.

WHY IT NEEDS A POLICY

Why create_shader needs a policy

Creating a shader file modifies the project by adding new content, but the operation is reversible (the file can be deleted or edited). This is a Write operation rather than Execute because it merely creates a file artifact without running code or triggering external side effects.

From the tool's definition Tool name 'create_shader' and description 'Create a new shader file' indicate file creation, a reversible write operation.

Verdict

create_shader Rate-limited

create_shader 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.

FAQ

Questions about create_shader

What does the create_shader tool do? +

Create a new shader file. It is categorised as a Write tool in the Godot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_shader? +

Register the Godot MCP Server MCP server in PolicyLayer and add a rule for create_shader: 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 MCP Server. Nothing to install.

What risk level is create_shader? +

create_shader is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_shader? +

Yes. Add a rate_limit block to the create_shader 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.

How do I block create_shader completely? +

Set action: deny in the PolicyLayer policy for create_shader. 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.

What MCP server provides create_shader? +

create_shader is provided by the Godot MCP Server MCP server (neondeex/godotmcp-pro-free-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
