WHAT IT DOES

What shader_create does on Godot Breakpoint

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

RISK

Why shader_create is rated Medium

This tool creates a new file resource (shader) in the Godot project. File creation is a reversible write operation—the file can be deleted or replaced. Although labeled 'DESTRUCTIVE' in the description, the confirmation gate means it requires explicit user acknowledgment before proceeding, preventing accidental creation.

From the tool's definition Tool description states it 'Create[s] a Shader resource with optional initial code and save it as a .gdshader file.' Creation of a new file is a write operation. The parenthetical note '(writes a file)' explicitly confirms the write nature.

RECOMMENDED RULE

The rule that runs shader_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For shader_create, this is the rule to start with:

shader_create Rate-limited

shader_create 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 shader_create

What does the shader_create tool do? +

Create a Shader resource with optional initial code and save it as a .gdshader file. DESTRUCTIVE (writes a file) — gated by confirmation. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on shader_create? +

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

What risk level is shader_create? +

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

Can I rate-limit shader_create? +

Yes. Add a rate_limit block to the shader_create 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 shader_create completely? +

Set action: deny in the PolicyLayer policy for shader_create. 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 shader_create? +

shader_create is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
