Why generate_layers needs a policy

The description is empty, so the exact behavior cannot be determined. Based on the name 'generate_layers' in the context of a Live2D automation server, it likely creates layered art assets (a Write operation), but without a description this is uncertain. Sibling tools suggest a pipeline for PSD/mesh/model generation, so this probably writes layer data.

From the tool's definition Tool name is 'generate_layers'; description is empty or uninformative.

POLICY

How to control generate_layers

PolicyLayer is an MCP gateway — it sits between your AI agents and Live2D Automation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_layers:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_layers": {
      "limits": [
        {
          "counter": "generate_layers_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_layers gets a rate cap, and everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about generate_layers

What does the generate_layers tool do? +

generate_layers. It is categorised as a Other tool in the Live2D Automation MCP Server MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on generate_layers? +

Register the Live2D Automation MCP Server MCP server in PolicyLayer and add a rule for generate_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 Live2D Automation MCP Server. Nothing to install.

What risk level is generate_layers? +

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

Can I rate-limit generate_layers? +

Yes. Add a rate_limit block to the generate_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.

How do I block generate_layers completely? +

Set action: deny in the PolicyLayer policy for generate_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.

What MCP server provides generate_layers? +

generate_layers is provided by the Live2D Automation MCP Server MCP server (j621111/live2d-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Live2D Automation MCP Server tool call.

Start from Live2D Automation MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
