create_gradient · Godot MCP: Risk & Policy

WHAT IT DOES

What create_gradient does on Godot

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

PARAMETERS

Parameter	Type	Required	Description
`path`	string	Yes	Output path (e.g. "gradients/fire.tres")
`colors`	object	—	Array of {offset, color} objects
`interpolation_mode`	object	—

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why create_gradient needs a policy

Creating a .tres resource file is a write operation that modifies the project filesystem by adding a new asset. While reversible (the file can be deleted), it persists changes to the project state. This is less severe than Execute (which could run arbitrary code) or Destructive (which cannot be undone), but more impactful than a pure Read operation.

From the tool's definition Tool creates a Gradient resource file (.tres format) in Godot. The description 'Create Gradient .tres' indicates the tool generates and saves a new resource asset.

Verdict

create_gradient Rate-limited

create_gradient 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_gradient

What does the create_gradient tool do? +

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

What parameters does create_gradient accept? +

create_gradient accepts 3 parameters: path, colors, interpolation_mode. Required: path. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on create_gradient? +

Register the Godot MCP server in PolicyLayer and add a rule for create_gradient: 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.

What risk level is create_gradient? +

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

Can I rate-limit create_gradient? +

Yes. Add a rate_limit block to the create_gradient 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_gradient completely? +

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

create_gradient 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.
