Close an image, optionally saving as XCF first. Parameters: - image_index: Index of the image to close (default 0) - save_first: If True, save as XCF before closing (default False) Returns status dict.
AI agents use close_image 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.
While closing an image might seem merely destructive (removing it from GIMP's state), the save_first parameter makes this tool primarily a Write operation—it creates or modifies XCF files on disk. The close action itself is reversible through reopening.
From the tool's definition Tool description states 'Close an image, optionally saving as XCF first' with parameter 'save_first' that triggers a save operation. The save operation modifies the filesystem by writing an XCF file, which is a reversible write action.
Documented attack patterns abuse exactly the kind of access close_image 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 close_image:
{
"version": "1",
"default": "deny",
"tools": {
"close_image": {
"limits": [
{
"counter": "close_image_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}close_image 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.

Close an image, optionally saving as XCF first. Parameters: - image_index: Index of the image to close (default 0) - save_first: If True, save as XCF before closing (default False) 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 close_image: 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.
close_image 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 close_image 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 close_image. 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.
close_image 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.
