Delete a layer from an image. Parameters: - layer_name: Name of the layer to delete - layer_index: Position index of the layer (alternative to layer_name) - image_index: Target image index (default 0) Provide either layer_name or layer_index.

AI agents call delete_layer to permanently remove resources in Gimp — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of image layers cannot be undone through the tool's parameters and represents irreversible data loss. While the impact is scoped to a single layer within an image (not affecting the entire file system), this is the most severe category applicable. An AI agent could accidentally or maliciously delete important layers from user artwork.
From the tool's definition Tool name is 'delete_layer' and description states 'Delete a layer from an image.' The operation removes a layer irreversibly from an image file.
Documented attack patterns abuse exactly the kind of access delete_layer gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Gimp, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_layer:
{
"version": "1",
"default": "deny",
"hide": [
"delete_layer"
]
}delete_layer disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a layer from an image. Parameters: - layer_name: Name of the layer to delete - layer_index: Position index of the layer (alternative to layer_name) - image_index: Target image index (default 0) Provide either layer_name or layer_index. Defaults to active layer if neither given. Returns status dict. It is categorised as a Destructive tool in the Gimp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Gimp MCP server in PolicyLayer and add a rule for delete_layer: 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 Gimp. Nothing to install.
delete_layer is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_layer 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 delete_layer. 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.
delete_layer is provided by the Gimp MCP server (maorcc/gimp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Gimp, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
