Get detailed information about a node by its ID
AI agents call getNodeInfo 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 retrieves metadata about a design element (node) in a Sketch file. It queries and returns information without modifying, executing, or deleting anything. The operation is read-only and safe—misuse would only expose design information, not compromise the file or system.
From the tool's definition Tool name 'getNodeInfo' and description 'Get detailed information about a node by its ID' indicate a retrieval operation.
Documented attack patterns abuse exactly the kind of access getNodeInfo 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 getNodeInfo:
{
"version": "1",
"default": "deny",
"tools": {
"getNodeInfo": {}
}
}getNodeInfo is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about 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 getNodeInfo: 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.
getNodeInfo 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 getNodeInfo 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 getNodeInfo. 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.
getNodeInfo 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.
