Get complete document structure with all pages and their hierarchies
AI agents call getDocumentStructure 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.
The tool retrieves and analyzes structural information from a Sketch design file. It reads document metadata and page hierarchies without side effects, data modification, code execution, or resource-destructive operations. This is a straightforward information retrieval task with minimal risk, appropriate to the Read category with low severity.
From the tool's definition Tool name and description indicate retrieval of document structure information: 'Get complete document structure with all pages and their hierarchies'.
Documented attack patterns abuse exactly the kind of access getDocumentStructure 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 getDocumentStructure:
{
"version": "1",
"default": "deny",
"tools": {
"getDocumentStructure": {}
}
}getDocumentStructure is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get complete document structure with all pages and their hierarchies. 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 getDocumentStructure: 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.
getDocumentStructure 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 getDocumentStructure 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 getDocumentStructure. 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.
getDocumentStructure 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.
