AI agents use create_layer to create or update resources in Inkscape — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Inkscape environment.
Creating a layer in Inkscape is a write operation that modifies the document structure but is fully reversible (layers can be deleted). The operation has no external side effects, does not execute arbitrary code, and does not destroy data irreversibly. Low severity due to limited blast radius—even if misused, the consequence is easily undone.
From the tool's definition Tool name 'create_layer' in Inkscape context indicates creation of a new layer, which is a reversible structural modification to a graphics document.
Documented attack patterns abuse exactly the kind of access create_layer gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Inkscape, and nothing reaches the server without passing your rules. This is the rule we recommend for create_layer:
{
"version": "1",
"default": "deny",
"tools": {
"create_layer": {
"limits": [
{
"counter": "create_layer_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_layer 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.

create_layer. It is categorised as a Write tool in the Inkscape MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Inkscape MCP server in PolicyLayer and add a rule for create_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 Inkscape. Nothing to install.
create_layer 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 create_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 create_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.
create_layer is provided by the Inkscape MCP server (sandraschi/inkscape-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Inkscape, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
