List layers in current document / 現在のドキュメントのレイヤーを一覧表示
AI agents call affinity_list_layers to retrieve information from MCP Affinity Designer Server 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 layer data from an open Affinity Designer document. It performs no side effects, does not modify, delete, or execute any operations—it simply enumerates existing layers. This is a straightforward Read operation with minimal risk if misused by an AI agent, as it cannot alter document state.
From the tool's definition Tool name 'affinity_list_layers' and description 'List layers in current document' indicate a read-only query operation that retrieves layer information without modification.
Documented attack patterns abuse exactly the kind of access affinity_list_layers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Affinity Designer Server, and nothing reaches the server without passing your rules. This is the rule we recommend for affinity_list_layers:
{
"version": "1",
"default": "deny",
"tools": {
"affinity_list_layers": {}
}
}affinity_list_layers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the MCP Affinity Designer Server MCP server in PolicyLayer and add a rule for affinity_list_layers: 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 MCP Affinity Designer Server. Nothing to install.
affinity_list_layers 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 affinity_list_layers 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 affinity_list_layers. 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.
affinity_list_layers is provided by the MCP Affinity Designer Server MCP server (szgk/mcp-affinity-designer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Affinity Designer Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
