Get the position of a node by its ID
AI agents call getNodePosition to retrieve information from Sketch without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns metadata (position coordinates) about a design element in a Sketch file. It is a read-only operation that retrieves information without side effects, state changes, or irreversible actions. No data is modified, executed, or destroyed. Misuse would at worst expose design layout information, presenting minimal security risk.
From the tool's definition Tool name 'getNodePosition' and description 'Get the position of a node by its ID' indicate a retrieval operation with no modification, deletion, or execution of external processes.
Documented attack patterns abuse exactly the kind of access getNodePosition gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sketch, and nothing reaches the server without passing your rules. This is the rule we recommend for getNodePosition:
{
"version": "1",
"default": "deny",
"tools": {
"getNodePosition": {}
}
}getNodePosition is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the position of a node by its ID. It is categorised as a Read tool in the Sketch MCP Server, which means it retrieves data without modifying state.
Register the Sketch MCP server in PolicyLayer and add a rule for getNodePosition: 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 Sketch. Nothing to install.
getNodePosition 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 getNodePosition 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 getNodePosition. 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.
getNodePosition is provided by the Sketch MCP server (mater1996/sketch-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sketch, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
