Apply Gaussian blur as a destructive filter operation. Parameters: - radius: Blur radius in pixels (default 5.0) - layer_name: Target layer; defaults to active layer - image_index: Target image index (default 0) Returns status dict.
AI agents use apply_gaussian_blur to create or update resources in Gimp — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gimp environment.
Despite the description using the word 'destructive,' this tool modifies pixel data on a layer in GIMP — an image editing operation that is reversible via undo within GIMP. It creates or modifies data (blurs pixels) but does not irreversibly delete or overwrite data in the sense of permanent data loss; GIMP's undo history can reverse it. This maps most closely to Write.

Documented attack patterns abuse exactly the kind of access apply_gaussian_blur 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 apply_gaussian_blur:
{
"version": "1",
"default": "deny",
"tools": {
"apply_gaussian_blur": {
"limits": [
{
"counter": "apply_gaussian_blur_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}apply_gaussian_blur 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.

Apply Gaussian blur as a destructive filter operation. Parameters: - radius: Blur radius in pixels (default 5.0) - layer_name: Target layer; defaults to active layer - image_index: Target image index (default 0) Returns status dict. It is categorised as a Write tool in the Gimp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Gimp MCP server in PolicyLayer and add a rule for apply_gaussian_blur: 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.
apply_gaussian_blur is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the apply_gaussian_blur 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 apply_gaussian_blur. 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.
apply_gaussian_blur 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.
