Why set_pattern_name needs a policy

Renaming is a reversible write operation that changes a property of an existing resource (pattern name). It does not execute external code, delete data, move funds, or have destructive effects. The blast radius is minimal—a user can simply rename it again. This fits the Write category.

From the tool's definition Tool function is to 'Rename a pattern piece' - a metadata update operation that modifies but does not irreversibly delete data.

Documented attack patterns abuse exactly the kind of access set_pattern_name gives an agent:

POLICY

How to control set_pattern_name

PolicyLayer is an MCP gateway — it sits between your AI agents and CLO3D MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for set_pattern_name:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_pattern_name": {
      "limits": [
        {
          "counter": "set_pattern_name_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_pattern_name stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register CLO3D MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about set_pattern_name

What does the set_pattern_name tool do? +

Rename a pattern piece. It is categorised as a Write tool in the CLO3D MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_pattern_name? +

Register the CLO3D MCP Server MCP server in PolicyLayer and add a rule for set_pattern_name: 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 CLO3D MCP Server. Nothing to install.

What risk level is set_pattern_name? +

set_pattern_name is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_pattern_name? +

Yes. Add a rate_limit block to the set_pattern_name 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 set_pattern_name completely? +

Set action: deny in the PolicyLayer policy for set_pattern_name. 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 set_pattern_name? +

set_pattern_name is provided by the CLO3D MCP Server MCP server (ubani-studio/clo3d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every CLO3D MCP Server tool call.

Start from CLO3D MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
