Why listPages needs a policy

This tool queries and returns information about pages in a Sketch design file without creating, modifying, deleting, or executing any operations. It is purely informational retrieval, matching the Read category definition.

From the tool's definition Tool name is 'listPages' and description states it 'List all pages in the Sketch document' — a retrieval operation with no modification or side effects.

POLICY

How to control listPages

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 listPages:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "listPages": {}
  }
}

listPages is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Sketch — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about listPages

What does the listPages tool do? +

List all pages in the Sketch document. It is categorised as a Read tool in the Sketch MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on listPages? +

Register the Sketch MCP server in PolicyLayer and add a rule for listPages: 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.

What risk level is listPages? +

listPages is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit listPages? +

Yes. Add a rate_limit block to the listPages 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.

How do I block listPages completely? +

Set action: deny in the PolicyLayer policy for listPages. 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.

What MCP server provides listPages? +

listPages 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.

Enforce policy on every Sketch tool call.

Start from Sketch, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
