Get the bounding rectangle of the current selection. Parameters: - image_index: Target image index (default 0) Returns: {has_selection, x, y, width, height}
AI agents call get_selection_bounds to retrieve information from Gimp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves information about an existing selection's bounding box coordinates and dimensions. It performs no modifications to the image, executes no external operations, and has no side effects. It is a pure read operation that returns data about the current state of GIMP. Confidence is high because the intent is unambiguous from both name and description.
From the tool's definition Tool name 'get_selection_bounds' and description 'Get the bounding rectangle of the current selection' indicate a query operation that retrieves selection metadata without modifying or executing operations on image data.
Documented attack patterns abuse exactly the kind of access get_selection_bounds 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 get_selection_bounds:
{
"version": "1",
"default": "deny",
"tools": {
"get_selection_bounds": {}
}
}get_selection_bounds is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the bounding rectangle of the current selection. Parameters: - image_index: Target image index (default 0) Returns: {has_selection, x, y, width, height}. It is categorised as a Read tool in the Gimp MCP Server, which means it retrieves data without modifying state.
Register the Gimp MCP server in PolicyLayer and add a rule for get_selection_bounds: 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.
get_selection_bounds is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_selection_bounds 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 get_selection_bounds. 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.
get_selection_bounds 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.
