set_layer_properties
AI agents use set_layer_properties 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.
This tool modifies vector graphic layers by adjusting their properties (e.g., visibility, opacity, blend mode, name). Such changes are Write-class because they alter document state reversibly—properties can be changed back or undone.
From the tool's definition Tool name is 'set_layer_properties' which implies modifying layer properties in Inkscape. The description is empty, limiting direct evidence, but the verb 'set' and context of a graphics editing tool indicate reversible modifications to document structure.
Documented attack patterns abuse exactly the kind of access set_layer_properties 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 set_layer_properties:
{
"version": "1",
"default": "deny",
"tools": {
"set_layer_properties": {
"limits": [
{
"counter": "set_layer_properties_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_layer_properties 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.

set_layer_properties. 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 set_layer_properties: 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.
set_layer_properties 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 set_layer_properties 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 set_layer_properties. 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.
set_layer_properties 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.
